The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction. The wall assembly is combination of six inch Structurally Insulated Panels (SIPs) and 2x6 stick frame construction filled with blown in insulation. The roof assembly is a combination of twelve inch SIPs and 2x12 stick frame construction filled with batt insulation. The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

Reimagining an Urban Classic Perched high above San Francisco’s Cow Hollow neighborhood, this meticulously reimagined residence represents a thoughtful transformation of a classic urban home into a contemporary, light-filled sanctuary. The project involved a comprehensive renovation paired with both vertical and horizontal expansion, dramatically increasing the home’s footprint while enhancing its relationship to sweeping views of the Bay, the Palace of Fine Arts, and the surrounding hillside neighborhoods. The design strategy focused on opening the home to light, air, and vistas—elements often constrained in the dense urban fabric of San Francisco. By extending the structure upward and outward, the architects created a dynamic four-level residence that unfolds gradually, culminating in expansive living spaces and rooftop terraces oriented toward panoramic city and water views. Architecture that Frames the View At the heart of the design is a careful orchestration of sightlines and natural light. Large black-framed windows punctuate the façade and interior spaces, deliberately positioned to capture iconic San Francisco vistas while flooding the home with daylight. The architecture prioritizes openness, allowing rooms to flow seamlessly while maintaining a strong visual connection to the surrounding landscape. A dramatic skylight above the central stairwell anchors the vertical circulation of the home. This architectural gesture not only brings daylight deep into the interior but also reinforces the sense of spatial continuity between floors. Warm Modern Interiors Inside, the home balances architectural clarity with warm materiality. Wide-plank oak floors run throughout the residence, creating visual cohesion and grounding the interiors with natural warmth. Custom walnut millwork—integrated shelving, cabinetry, and wall panels—introduces depth and texture while complementing the clean lines of the architecture. The interiors are intentionally restrained yet richly layered. Contemporary furnishings, sculptural lighting, and curated artwork add personality while maintaining the calm, sophisticated palette that defines the home. The Social Heart of the Home The main living level serves as the social centerpiece of the residence. An open-plan kitchen, dining area, and lounge space unfold toward the view, creating an environment that feels both expansive and intimate. A sculptural marble island anchors the kitchen, functioning as both workspace and gathering hub. Surrounded by walnut cabinetry and professional-grade appliances, the kitchen merges elegance with functionality. Above, a cascading chandelier introduces a sense of vertical movement, reflecting the home’s emphasis on light and architectural rhythm. Living areas are arranged to encourage conversation and connection. Generous seating, layered rugs, and thoughtful lighting define distinct zones within the open plan while maintaining uninterrupted sightlines toward the cityscape beyond. Private Retreats Above the City Upper levels of the home are dedicated to quieter, more intimate spaces. The primary suite is conceived as a private retreat, where expansive windows frame treetop views and invite natural light throughout the day. The accompanying bathroom continues the home’s refined material palette. Marble surfaces, warm wood cabinetry, and brushed brass fixtures create a spa-like environment that balances luxury with tranquility. Additional bedrooms and flexible living spaces offer comfort for family and guests, each designed with the same attention to light, proportion, and material richness. Spaces for Entertaining Lower levels provide additional areas for gathering and entertaining. A lounge and bar area offer a relaxed setting for hosting, while custom wine storage adds a sophisticated touch for collectors and enthusiasts. These spaces transition easily to outdoor areas, reinforcing the home’s emphasis on indoor-outdoor living. A Rooftop Above the Neighborhood The transformation extends beyond the interior to include thoughtfully designed outdoor spaces. A landscaped rear yard introduces greenery and privacy at ground level, offering a serene urban escape. Above it all, the rooftop terrace becomes the crown jewel of the residence. Elevated above the neighborhood, it provides sweeping views of the San Francisco Bay and the Palace of Fine Arts. Comfortable seating areas, lush planters, and open sky create an ideal setting for outdoor entertaining, sunset gatherings, or quiet moments overlooking the city. A Contemporary Urban Sanctuary The completed residence demonstrates the power of thoughtful renovation and expansion within a historic urban neighborhood. By combining contemporary architecture, warm materiality, and an intentional relationship to the surrounding landscape, the project transforms a traditional San Francisco home into a modern sanctuary above the city.

From Mid-Century Classic to the Present An iconic design updated with comfort, function, and flow for today. A Remodel That Balances Past and Present What started as a desire to update a classic Eichler soon became an exploration of how Mid-Century Modern design can successfully evolve for today. The client, a tech professional with a passion for scuba diving and underwater photography, wanted a home that would both honor its original character and feel tailored to his daily life. A lifelong technology enthusiast, he still owns the very first Mac desktop he saved up for as a teenager working at Radio Shack, a detail that underscores his appreciation for design that melds function and form. Honoring Separation While Expanding Possibility Unlike many contemporary remodels where walls are opened up to create expansive living spaces, this project took a more restrained approach. The client valued the defined rooms of the original plan and wanted to preserve as much wall space as possible for displaying his large-format underwater photography. The emphasis was not on dramatic spatial reinvention, but on thoughtful refinements. Klopf Architecture shaped a gallery-like backdrop while also expanding the primary suite, modernizing materials and fixtures throughout the home, and improving the functionality and layout of the kitchen. The finished home feels at once timeless and renewed, an Eichler that continues to inspire while fully supporting the lifestyle of its present-day owner. A major turning point came mid-design. The original project brief had not included an addition, but as the reconfiguration of the primary bedroom and bath unfolded, it became clear that an expansion was the best approach to achieve the client’s vision of a more spacious suite. Fortunately, the adjustment came at a stage when revisions were still manageable and was integrated seamlessly, showing how thoughtful course corrections can strengthen a project rather than hinder it. Navigating Challenges With Precision The design development included multiple conceptual rounds, balancing preservation with subtle expansion. During construction, an existing post previously thought to be load-bearing turned out not to be. The structural engineer was able to pivot quickly, and both the post and the cross beam that had been intended to replace it could be omitted, allowing the original rhythm of the Eichler beam bays to be preserved. Sustainability was not just a checklist item, but a way to align the home with the client’s values of simplicity, efficiency, and long-term functionality. R-38 roof insulation reduced energy usage, solar panels with battery storage provided independence and resilience, and passive comfort strategies eliminated the need forenergy-intensive air conditioning. An electric vehicle charger and an on-demand hot water recirculation system (with call buttons as opposed to having constant circulation) add to the home’s long-term efficiency factors. Together, these moves created a home that is quieter, more comfortable, and better equipped for the future, qualities that supported the client’s pragmatic approach to design and living lightly. Details That Respect the Eichler DNA The remodel carries forward the Eichler’s original spirit while introducing new layers of modern livability. Originally, the house was approached along a deep, narrow walk, with the garage on one side and the house on the other, leaving the front door tucked far back within this chasm-like space. By pulling the entry forward, the design reshaped the arrival experience, creating a clearer threshold and a natural drop-off zone for bags, shoes, and keys. This shift also made room for a custom bench at the entry that extends seamlessly through the glass sidelight. The bench and drop-off zone now work together as a single, integrated sequence that supports everyday living while offering a tactile reminder of Eichler’s philosophy of connectedness. At the client’s request, Klopf reintroduced a classic Eichler gesture by extending the exterior siding into the entry and living room. The detail reinforces a sense of indoor/outdoor continuity while providing a subtle architectural surface that allows the client’s photography to take visual precedence. The signature concrete masonry wall at the front was reconstructed using blocks sourced to match the originals, now strengthened with rebar for seismic resilience while maintaining a private outdoor courtyard, visually extending the kitchen outward. A decorative trellis element, a detail borrowed from a neighboring Eichler, restores a familiar mid-century modern architectural motif. At the courtyard entry door, a custom etched glass sidelight with an ocean-themed design featuring kelp and jellyfish serves as a subtle homage to the client’s passion for deep-sea diving. Landscaping became an integral part of the overall transformation. The homeowner engaged landscape architect Randi Johnsen of Third Nature Studio to shape a series of calm, inviting outdoor rooms that read as a natural extension of the interiors. While technically outside of the core construction scope, the landscape design proved central to achieving a sense of completeness and connectedness across the property. Such whole-property considerations often emerge as design ideas take shape, underscoring the importance of flexibility in planning and budgeting, as well as close collaboration among the design team starting early in the process. The Value of Evolving Scope As with many custom residential projects, the scope evolved during the design process. What began as a targeted remodel grew to include a new/expanded primary suite, a rebuilt CMU patio wall for strength and longevity, and a solar panel array and battery storage for energy resilience and carbon-reduction. Each thoughtful decision represented a conscious investment in the home’s performance and character, rather than a cost overrun. The result was a project delivered on schedule, tailored precisely to the client’s lifestyle, and positioned to add long-term value both functionally and aesthetically. By embracing scope evolution as an opportunity rather than a challenge, and relying on good design paired with transparent communication, this remodel demonstrates how Eichler homes can be adapted for contemporary living without erasing their DNA.

At the client’s request, Klopf reintroduced a classic Eichler gesture by extending the exterior siding into the entry and living room. The detail reinforces a sense of indoor/outdoor continuity while providing a subtle architectural surface that allows the client’s photography to take visual precedence. The signature concrete masonry wall at the front was reconstructed using blocks sourced to match the originals, now strengthened with rebar for seismic resilience while maintaining a private outdoor courtyard, visually extending the kitchen outward. A decorative trellis element, a detail borrowed from a neighboring Eichler, restores a familiar mid-century modern architectural motif. At the courtyard entry door, a custom etched glass sidelight with an ocean-themed design featuring kelp and jellyfish serves as a subtle homage to the client’s passion for deep-sea diving. Landscaping became an integral part of the overall transformation. The homeowner engaged landscape architect Randi Johnsen of Third Nature Studio to shape a series of calm, inviting outdoor rooms that read as a natural extension of the interiors. While technically outside of the core construction scope, the landscape design proved central to achieving a sense of completeness and connectedness across the property. Such whole-property considerations often emerge as design ideas take shape, underscoring the importance of flexibility in planning and budgeting, as well as close collaboration among the design team starting early in the process. The Value of Evolving Scope As with many custom residential projects, the scope evolved during the design process. What began as a targeted remodel grew to include a new/expanded primary suite, a rebuilt CMU patio wall for strength and longevity, and a solar panel array and battery storage for energy resilience and carbon-reduction. Each thoughtful decision represented a conscious investment in the home’s performance and character, rather than a cost overrun. The result was a project delivered on schedule, tailored precisely to the client’s lifestyle, and positioned to add long-term value both functionally and aesthetically. By embracing scope evolution as an opportunity rather than a challenge, and relying on good design paired with transparent communication, this remodel demonstrates how Eichler homes can be adapted for contemporary living without erasing their DNA.

Reimagining an Urban Classic Perched high above San Francisco’s Cow Hollow neighborhood, this meticulously reimagined residence represents a thoughtful transformation of a classic urban home into a contemporary, light-filled sanctuary. The project involved a comprehensive renovation paired with both vertical and horizontal expansion, dramatically increasing the home’s footprint while enhancing its relationship to sweeping views of the Bay, the Palace of Fine Arts, and the surrounding hillside neighborhoods. The design strategy focused on opening the home to light, air, and vistas—elements often constrained in the dense urban fabric of San Francisco. By extending the structure upward and outward, the architects created a dynamic four-level residence that unfolds gradually, culminating in expansive living spaces and rooftop terraces oriented toward panoramic city and water views. Architecture that Frames the View At the heart of the design is a careful orchestration of sightlines and natural light. Large black-framed windows punctuate the façade and interior spaces, deliberately positioned to capture iconic San Francisco vistas while flooding the home with daylight. The architecture prioritizes openness, allowing rooms to flow seamlessly while maintaining a strong visual connection to the surrounding landscape. A dramatic skylight above the central stairwell anchors the vertical circulation of the home. This architectural gesture not only brings daylight deep into the interior but also reinforces the sense of spatial continuity between floors. Warm Modern Interiors Inside, the home balances architectural clarity with warm materiality. Wide-plank oak floors run throughout the residence, creating visual cohesion and grounding the interiors with natural warmth. Custom walnut millwork—integrated shelving, cabinetry, and wall panels—introduces depth and texture while complementing the clean lines of the architecture. The interiors are intentionally restrained yet richly layered. Contemporary furnishings, sculptural lighting, and curated artwork add personality while maintaining the calm, sophisticated palette that defines the home. The Social Heart of the Home The main living level serves as the social centerpiece of the residence. An open-plan kitchen, dining area, and lounge space unfold toward the view, creating an environment that feels both expansive and intimate. A sculptural marble island anchors the kitchen, functioning as both workspace and gathering hub. Surrounded by walnut cabinetry and professional-grade appliances, the kitchen merges elegance with functionality. Above, a cascading chandelier introduces a sense of vertical movement, reflecting the home’s emphasis on light and architectural rhythm. Living areas are arranged to encourage conversation and connection. Generous seating, layered rugs, and thoughtful lighting define distinct zones within the open plan while maintaining uninterrupted sightlines toward the cityscape beyond. Private Retreats Above the City Upper levels of the home are dedicated to quieter, more intimate spaces. The primary suite is conceived as a private retreat, where expansive windows frame treetop views and invite natural light throughout the day. The accompanying bathroom continues the home’s refined material palette. Marble surfaces, warm wood cabinetry, and brushed brass fixtures create a spa-like environment that balances luxury with tranquility. Additional bedrooms and flexible living spaces offer comfort for family and guests, each designed with the same attention to light, proportion, and material richness. Spaces for Entertaining Lower levels provide additional areas for gathering and entertaining. A lounge and bar area offer a relaxed setting for hosting, while custom wine storage adds a sophisticated touch for collectors and enthusiasts. These spaces transition easily to outdoor areas, reinforcing the home’s emphasis on indoor-outdoor living. A Rooftop Above the Neighborhood The transformation extends beyond the interior to include thoughtfully designed outdoor spaces. A landscaped rear yard introduces greenery and privacy at ground level, offering a serene urban escape. Above it all, the rooftop terrace becomes the crown jewel of the residence. Elevated above the neighborhood, it provides sweeping views of the San Francisco Bay and the Palace of Fine Arts. Comfortable seating areas, lush planters, and open sky create an ideal setting for outdoor entertaining, sunset gatherings, or quiet moments overlooking the city. A Contemporary Urban Sanctuary The completed residence demonstrates the power of thoughtful renovation and expansion within a historic urban neighborhood. By combining contemporary architecture, warm materiality, and an intentional relationship to the surrounding landscape, the project transforms a traditional San Francisco home into a modern sanctuary above the city.

The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction. The wall assembly is combination of six inch Structurally Insulated Panels (SIPs) and 2x6 stick frame construction filled with blown in insulation. The roof assembly is a combination of twelve inch SIPs and 2x12 stick frame construction filled with batt insulation. The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

From Mid-Century Classic to the Present An iconic design updated with comfort, function, and flow for today. A Remodel That Balances Past and Present What started as a desire to update a classic Eichler soon became an exploration of how Mid-Century Modern design can successfully evolve for today. The client, a tech professional with a passion for scuba diving and underwater photography, wanted a home that would both honor its original character and feel tailored to his daily life. A lifelong technology enthusiast, he still owns the very first Mac desktop he saved up for as a teenager working at Radio Shack, a detail that underscores his appreciation for design that melds function and form. Honoring Separation While Expanding Possibility Unlike many contemporary remodels where walls are opened up to create expansive living spaces, this project took a more restrained approach. The client valued the defined rooms of the original plan and wanted to preserve as much wall space as possible for displaying his large-format underwater photography. The emphasis was not on dramatic spatial reinvention, but on thoughtful refinements. Klopf Architecture shaped a gallery-like backdrop while also expanding the primary suite, modernizing materials and fixtures throughout the home, and improving the functionality and layout of the kitchen. The finished home feels at once timeless and renewed, an Eichler that continues to inspire while fully supporting the lifestyle of its present-day owner. A major turning point came mid-design. The original project brief had not included an addition, but as the reconfiguration of the primary bedroom and bath unfolded, it became clear that an expansion was the best approach to achieve the client’s vision of a more spacious suite. Fortunately, the adjustment came at a stage when revisions were still manageable and was integrated seamlessly, showing how thoughtful course corrections can strengthen a project rather than hinder it. Navigating Challenges With Precision The design development included multiple conceptual rounds, balancing preservation with subtle expansion. During construction, an existing post previously thought to be load-bearing turned out not to be. The structural engineer was able to pivot quickly, and both the post and the cross beam that had been intended to replace it could be omitted, allowing the original rhythm of the Eichler beam bays to be preserved. Sustainability was not just a checklist item, but a way to align the home with the client’s values of simplicity, efficiency, and long-term functionality. R-38 roof insulation reduced energy usage, solar panels with battery storage provided independence and resilience, and passive comfort strategies eliminated the need forenergy-intensive air conditioning. An electric vehicle charger and an on-demand hot water recirculation system (with call buttons as opposed to having constant circulation) add to the home’s long-term efficiency factors. Together, these moves created a home that is quieter, more comfortable, and better equipped for the future, qualities that supported the client’s pragmatic approach to design and living lightly. Details That Respect the Eichler DNA The remodel carries forward the Eichler’s original spirit while introducing new layers of modern livability. Originally, the house was approached along a deep, narrow walk, with the garage on one side and the house on the other, leaving the front door tucked far back within this chasm-like space. By pulling the entry forward, the design reshaped the arrival experience, creating a clearer threshold and a natural drop-off zone for bags, shoes, and keys. This shift also made room for a custom bench at the entry that extends seamlessly through the glass sidelight. The bench and drop-off zone now work together as a single, integrated sequence that supports everyday living while offering a tactile reminder of Eichler’s philosophy of connectedness.

From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

Reimagining an Urban Classic Perched high above San Francisco’s Cow Hollow neighborhood, this meticulously reimagined residence represents a thoughtful transformation of a classic urban home into a contemporary, light-filled sanctuary. The project involved a comprehensive renovation paired with both vertical and horizontal expansion, dramatically increasing the home’s footprint while enhancing its relationship to sweeping views of the Bay, the Palace of Fine Arts, and the surrounding hillside neighborhoods. The design strategy focused on opening the home to light, air, and vistas—elements often constrained in the dense urban fabric of San Francisco. By extending the structure upward and outward, the architects created a dynamic four-level residence that unfolds gradually, culminating in expansive living spaces and rooftop terraces oriented toward panoramic city and water views. Architecture that Frames the View At the heart of the design is a careful orchestration of sightlines and natural light. Large black-framed windows punctuate the façade and interior spaces, deliberately positioned to capture iconic San Francisco vistas while flooding the home with daylight. The architecture prioritizes openness, allowing rooms to flow seamlessly while maintaining a strong visual connection to the surrounding landscape. A dramatic skylight above the central stairwell anchors the vertical circulation of the home. This architectural gesture not only brings daylight deep into the interior but also reinforces the sense of spatial continuity between floors. Warm Modern Interiors Inside, the home balances architectural clarity with warm materiality. Wide-plank oak floors run throughout the residence, creating visual cohesion and grounding the interiors with natural warmth. Custom walnut millwork—integrated shelving, cabinetry, and wall panels—introduces depth and texture while complementing the clean lines of the architecture. The interiors are intentionally restrained yet richly layered. Contemporary furnishings, sculptural lighting, and curated artwork add personality while maintaining the calm, sophisticated palette that defines the home. The Social Heart of the Home The main living level serves as the social centerpiece of the residence. An open-plan kitchen, dining area, and lounge space unfold toward the view, creating an environment that feels both expansive and intimate. A sculptural marble island anchors the kitchen, functioning as both workspace and gathering hub. Surrounded by walnut cabinetry and professional-grade appliances, the kitchen merges elegance with functionality. Above, a cascading chandelier introduces a sense of vertical movement, reflecting the home’s emphasis on light and architectural rhythm. Living areas are arranged to encourage conversation and connection. Generous seating, layered rugs, and thoughtful lighting define distinct zones within the open plan while maintaining uninterrupted sightlines toward the cityscape beyond. Private Retreats Above the City Upper levels of the home are dedicated to quieter, more intimate spaces. The primary suite is conceived as a private retreat, where expansive windows frame treetop views and invite natural light throughout the day. The accompanying bathroom continues the home’s refined material palette. Marble surfaces, warm wood cabinetry, and brushed brass fixtures create a spa-like environment that balances luxury with tranquility. Additional bedrooms and flexible living spaces offer comfort for family and guests, each designed with the same attention to light, proportion, and material richness. Spaces for Entertaining Lower levels provide additional areas for gathering and entertaining. A lounge and bar area offer a relaxed setting for hosting, while custom wine storage adds a sophisticated touch for collectors and enthusiasts. These spaces transition easily to outdoor areas, reinforcing the home’s emphasis on indoor-outdoor living. A Rooftop Above the Neighborhood The transformation extends beyond the interior to include thoughtfully designed outdoor spaces. A landscaped rear yard introduces greenery and privacy at ground level, offering a serene urban escape. Above it all, the rooftop terrace becomes the crown jewel of the residence. Elevated above the neighborhood, it provides sweeping views of the San Francisco Bay and the Palace of Fine Arts. Comfortable seating areas, lush planters, and open sky create an ideal setting for outdoor entertaining, sunset gatherings, or quiet moments overlooking the city. A Contemporary Urban Sanctuary The completed residence demonstrates the power of thoughtful renovation and expansion within a historic urban neighborhood. By combining contemporary architecture, warm materiality, and an intentional relationship to the surrounding landscape, the project transforms a traditional San Francisco home into a modern sanctuary above the city.
