Klopf Architecture
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.

ZeroEnergy DesignThis renovated brick rowhome in Boston’s South End offers a modern aesthetic within a historic structure, creative use of space, exceptional thermal comfort, a reduced carbon footprint, and a passive stream of income.
DESIGN PRIORITIES. The goals for the project were clear - design the primary unit to accommodate the family’s modern lifestyle, rework the layout to create a desirable rental unit, improve thermal comfort and introduce a modern aesthetic. We designed the street-level entry as a shared entrance for both the primary and rental unit. The family uses it as their everyday entrance - we planned for bike storage and an open mudroom with bench and shoe storage to facilitate the change from shoes to slippers or bare feet as they enter their home. On the main level, we expanded the kitchen into the dining room to create an eat-in space with generous counter space and storage, as well as a comfortable connection to the living space. The second floor serves as master suite for the couple - a bedroom with a walk-in-closet and ensuite bathroom, and an adjacent study, with refinished original pumpkin pine floors. The upper floor, aside from a guest bedroom, is the child's domain with interconnected spaces for sleeping, work and play. In the play space, which can be separated from the work space with new translucent sliding doors, we incorporated recreational features inspired by adventurous and competitive television shows, at their son’s request.
MODERN MEETS TRADITIONAL. We left the historic front facade of the building largely unchanged - the security bars were removed from the windows and the single pane windows were replaced with higher performing historic replicas. We designed the interior and rear facade with a vision of warm modernism, weaving in the notable period features. Each element was either restored or reinterpreted to blend with the modern aesthetic. The detailed ceiling in the living space, for example, has a new matte monochromatic finish, and the wood stairs are covered in a dark grey floor paint, whereas the mahogany doors were simply refinished. New wide plank wood flooring with a neutral finish, floor-to-ceiling casework, and bold splashes of color in wall paint and tile, and oversized high-performance windows (on the rear facade) round out the modern aesthetic.
RENTAL INCOME. The existing rowhome was zoned for a 2-family dwelling but included an undesirable, single-floor studio apartment at the garden level with low ceiling heights and questionable emergency egress. In order to increase the quality and quantity of space in the rental unit, we reimagined it as a two-floor, 1 or 2 bedroom, 2 bathroom apartment with a modern aesthetic, increased ceiling height on the lowest level and provided an in-unit washer/dryer. The apartment was listed with Jackie O'Connor Real Estate and rented immediately, providing the owners with a source of passive income.
ENCLOSURE WITH BENEFITS. The homeowners sought a minimal carbon footprint, enabled by their urban location and lifestyle decisions, paired with the benefits of a high-performance home. The extent of the renovation allowed us to implement a deep energy retrofit (DER) to address air tightness, insulation, and high-performance windows. The historic front facade is insulated from the interior, while the rear facade is insulated on the exterior. Together with these building enclosure improvements, we designed an HVAC system comprised of continuous fresh air ventilation, and an efficient, all-electric heating and cooling system to decouple the house from natural gas. This strategy provides optimal thermal comfort and indoor air quality, improved acoustic isolation from street noise and neighbors, as well as a further reduced carbon footprint. We also took measures to prepare the roof for future solar panels, for when the South End neighborhood’s aging electrical infrastructure is upgraded to allow them.
URBAN LIVING. The desirable neighborhood location allows the both the homeowners and tenant to walk, bike, and use public transportation to access the city, while each charging their respective plug-in electric cars behind the building to travel greater distances.
OVERALL. The understated rowhouse is now ready for another century of urban living, offering the owners comfort and convenience as they live life as an expression of their values.

Dream Coast BuildersDuring this kitchen renovation, we reconfigured the entire layout to support a more fluid, open-concept kitchen experience. The expanded island was constructed to anchor daily living and gather guests, complementing the clean geometry of modern kitchen cabinets and integrated modern kitchen appliances. Warm materials soften the strong architectural lines, contributing to a luxury home design that feels inviting while retaining modern kitchen design sophistication. We incorporated modular kitchen ideas to improve storage and movement, ensuring the homeowners enjoy both beauty and efficiency. This reimagined space showcases the craftsmanship behind luxury custom homes and reflects our commitment to modern luxury living. The result brings together modern kitchen remodel strategies with home remodeling ideas tailored for contemporary coastal architecture.
ZeroEnergy DesignThis modern green home offers both a vacation destination on Cape Cod near local family members and an opportunity for rental income.
FAMILY ROOTS. A West Coast couple living in the San Francisco Bay Area sought a permanent East Coast vacation home near family members living on Cape Cod. As academic professionals focused on sustainability, they sought a green, energy efficient home that was well-aligned with their values. With no green homes available for sale on Cape Cod, they decided to purchase land near their family and build their own.
SLOPED SITE. Comprised of a 3/4 acre lot nestled in the pines, the steeply sloping terrain called for a plan that embraced and took advantage of the slope. Of equal priority was optimizing solar exposure, preserving privacy from abutters, and creating outdoor living space. The design accomplished these goals with a simple, rectilinear form, offering living space on the both entry and lower/basement levels. The stepped foundation allows for a walk-out basement level with light-filled living space on the down-hill side of the home. The traditional basement on the eastern, up-hill side houses mechanical equipment and a home gym. The house welcomes natural light throughout, captures views of the forest, and delivers entertainment space that connects indoor living space to outdoor deck and dining patio.
MODERN VISION. The clean building form and uncomplicated finishes pay homage to the modern architectural legacy on the outer Cape. Durable and economical fiber cement panels, fixed with aluminum channels, clad the primary form. Cedar clapboards provide a visual accent at the south-facing living room, which extends a single roof plane to cover the entry porch.
SMART USE OF SPACE. On the entry level, the “L”-shaped living, dining, and kitchen space connects to the exterior living, dining, and grilling spaces to effectively double the home’s summertime entertainment area. Placed at the western end of the entry level (where it can retain privacy but still claim expansive downhill views) is the master suite with a built-in study. The lower level has two guest bedrooms, a second full bathroom, and laundry. The flexibility of the space—crucial in a house with a modest footprint—emerges in one of the guest bedrooms, which doubles as home office by opening the barn-style double doors to connect it to the bright, airy open stair leading up to the entry level. Thoughtful design, generous ceiling heights and large windows transform the modest 1,100 sf* footprint into a well-lit, spacious home. *(total finished space is 1800 sf)
RENTAL INCOME. The property works for its owners by netting rental income when the owners are home in San Francisco. The house especially caters to vacationers bound for nearby Mayo Beach and includes an outdoor shower adjacent to the lower level entry door. In contrast to the bare bones cottages that are typically available on the Cape, this home offers prospective tenants a modern aesthetic, paired with luxurious and green features. Durable finishes inside and out will ensure longevity with the heavier use that comes with a rental property.
COMFORT YEAR-ROUND. The home is super-insulated and air-tight, with mechanical ventilation to provide continuous fresh air from the outside. High performance triple-paned windows complement the building enclosure and maximize passive solar gain while ensuring a warm, draft-free winter, even when sitting close to the glass. A properly sized air source heat pump offers efficient heating & cooling, and includes a carefully designed the duct distribution system to provide even comfort throughout the house. The super-insulated envelope allows us to significantly reduce the equipment capacity, duct size, and airflow quantities, while maintaining unparalleled thermal comfort.
ENERGY EFFICIENT. The building’s shell and mechanical systems play instrumental roles in the home’s exceptional performance. The building enclosure reduces the most significant energy glutton: heating. Continuous super-insulation, thorough air sealing, triple-pane windows, and passive solar gain work together to yield a miniscule heating load. All active energy consumers are extremely efficient: an air source heat pump for heating and cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation (ERV), and high efficiency appliances. The result is a home that uses 70% less energy than a similar new home built to code requirements.
OVERALL. The home embodies the owners’ goals and values while comprehensively enabling thermal comfort, energy efficiency, a vacation respite, and supplementary income.

Bellingham Bay BuildersThe 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.

The objective of this award-winning gut renovation was to create a spatially dynamic, light-filled, and energy-efficient home with a strong connection to Long Island Sound. The design strategy is straightforward: a gabled roof covers a central “spine” corridor that terminates with cathedral ceilinged spaces at both ends. The relocated approach and entry deposit visitors into the front hall with its curvilinear, cantilevered stair. A two-story, windowed family gathering space lies ahead – a straight shot to the water beyond.
The design challenge was to utilize the existing house footprint and structure, while raising the top of foundation walls to exceed new flood regulations, reconfiguring the spatial organization, and using innovative materials to produce a tight thermal envelope and contemporary yet contextually appropriate facades.
John Webb Construction and DesignThis countryside farmhouse was remodeled and added on to by removing an interior wall separating the kitchen from the dining/living room, putting an addition at the porch to extend the kitchen by 10', installing an IKEA kitchen cabinets and custom built island using IKEA boxes, custom IKEA fronts, panels, trim, copper and wood trim exhaust wood, wolf appliances, apron front sink, and quartz countertop. The bathroom was redesigned with relocation of the walk-in shower, and installing a pottery barn vanity. the main space of the house was completed with luxury vinyl plank flooring throughout. A beautiful transformation with gorgeous views of the Willamette Valley.

In the play space, which can be separated from the work space with new translucent sliding doors, we incorporated recreational features inspired by adventurous and competitive television shows, at their son’s request.
MODERN MEETS TRADITIONAL. We left the historic front facade of the building largely unchanged - the security bars were removed from the windows and the single pane windows were replaced with higher performing historic replicas. We designed the interior and rear facade with a vision of warm modernism, weaving in the notable period features. Each element was either restored or reinterpreted to blend with the modern aesthetic. The detailed ceiling in the living space, for example, has a new matte monochromatic finish, and the wood stairs are covered in a dark grey floor paint, whereas the mahogany doors were simply refinished. New wide plank wood flooring with a neutral finish, floor-to-ceiling casework, and bold splashes of color in wall paint and tile, and oversized high-performance windows (on the rear facade) round out the modern aesthetic.
RENTAL INCOME. The existing rowhome was zoned for a 2-family dwelling but included an undesirable, single-floor studio apartment at the garden level with low ceiling heights and questionable emergency egress. In order to increase the quality and quantity of space in the rental unit, we reimagined it as a two-floor, 1 or 2 bedroom, 2 bathroom apartment with a modern aesthetic, increased ceiling height on the lowest level and provided an in-unit washer/dryer. The apartment was listed with Jackie O'Connor Real Estate and rented immediately, providing the owners with a source of passive income.
ENCLOSURE WITH BENEFITS. The homeowners sought a minimal carbon footprint, enabled by their urban location and lifestyle decisions, paired with the benefits of a high-performance home. The extent of the renovation allowed us to implement a deep energy retrofit (DER) to address air tightness, insulation, and high-performance windows. The historic front facade is insulated from the interior, while the rear facade is insulated on the exterior. Together with these building enclosure improvements, we designed an HVAC system comprised of continuous fresh air ventilation, and an efficient, all-electric heating and cooling system to decouple the house from natural gas. This strategy provides optimal thermal comfort and indoor air quality, improved acoustic isolation from street noise and neighbors, as well as a further reduced carbon footprint. We also took measures to prepare the roof for future solar panels, for when the South End neighborhood’s aging electrical infrastructure is upgraded to allow them.
URBAN LIVING. The desirable neighborhood location allows the both the homeowners and tenant to walk, bike, and use public transportation to access the city, while each charging their respective plug-in electric cars behind the building to travel greater distances.
OVERALL. The understated rowhouse is now ready for another century of urban living, offering the owners comfort and convenience as they live life as an expression of their values.

ZeroEnergy DesignThis renovated brick rowhome in Boston’s South End offers a modern aesthetic within a historic structure, creative use of space, exceptional thermal comfort, a reduced carbon footprint, and a passive stream of income.
DESIGN PRIORITIES. The goals for the project were clear - design the primary unit to accommodate the family’s modern lifestyle, rework the layout to create a desirable rental unit, improve thermal comfort and introduce a modern aesthetic. We designed the street-level entry as a shared entrance for both the primary and rental unit. The family uses it as their everyday entrance - we planned for bike storage and an open mudroom with bench and shoe storage to facilitate the change from shoes to slippers or bare feet as they enter their home. On the main level, we expanded the kitchen into the dining room to create an eat-in space with generous counter space and storage, as well as a comfortable connection to the living space. The second floor serves as master suite for the couple - a bedroom with a walk-in-closet and ensuite bathroom, and an adjacent study, with refinished original pumpkin pine floors. The upper floor, aside from a guest bedroom, is the child's domain with interconnected spaces for sleeping, work and play.

ZeroEnergy DesignThis modern green home offers both a vacation destination on Cape Cod near local family members and an opportunity for rental income.
FAMILY ROOTS. A West Coast couple living in the San Francisco Bay Area sought a permanent East Coast vacation home near family members living on Cape Cod. As academic professionals focused on sustainability, they sought a green, energy efficient home that was well-aligned with their values. With no green homes available for sale on Cape Cod, they decided to purchase land near their family and build their own.
SLOPED SITE. Comprised of a 3/4 acre lot nestled in the pines, the steeply sloping terrain called for a plan that embraced and took advantage of the slope. Of equal priority was optimizing solar exposure, preserving privacy from abutters, and creating outdoor living space. The design accomplished these goals with a simple, rectilinear form, offering living space on the both entry and lower/basement levels. The stepped foundation allows for a walk-out basement level with light-filled living space on the down-hill side of the home. The traditional basement on the eastern, up-hill side houses mechanical equipment and a home gym. The house welcomes natural light throughout, captures views of the forest, and delivers entertainment space that connects indoor living space to outdoor deck and dining patio.
MODERN VISION. The clean building form and uncomplicated finishes pay homage to the modern architectural legacy on the outer Cape. Durable and economical fiber cement panels, fixed with aluminum channels, clad the primary form. Cedar clapboards provide a visual accent at the south-facing living room, which extends a single roof plane to cover the entry porch.
SMART USE OF SPACE. On the entry level, the “L”-shaped living, dining, and kitchen space connects to the exterior living, dining, and grilling spaces to effectively double the home’s summertime entertainment area. Placed at the western end of the entry level (where it can retain privacy but still claim expansive downhill views) is the master suite with a built-in study. The lower level has two guest bedrooms, a second full bathroom, and laundry. The flexibility of the space—crucial in a house with a modest footprint—emerges in one of the guest bedrooms, which doubles as home office by opening the barn-style double doors to connect it to the bright, airy open stair leading up to the entry level. Thoughtful design, generous ceiling heights and large windows transform the modest 1,100 sf* footprint into a well-lit, spacious home. *(total finished space is 1800 sf)
RENTAL INCOME. The property works for its owners by netting rental income when the owners are home in San Francisco. The house especially caters to vacationers bound for nearby Mayo Beach and includes an outdoor shower adjacent to the lower level entry door. In contrast to the bare bones cottages that are typically available on the Cape, this home offers prospective tenants a modern aesthetic, paired with luxurious and green features. Durable finishes inside and out will ensure longevity with the heavier use that comes with a rental property.
COMFORT YEAR-ROUND. The home is super-insulated and air-tight, with mechanical ventilation to provide continuous fresh air from the outside. High performance triple-paned windows complement the building enclosure and maximize passive solar gain while ensuring a warm, draft-free winter, even when sitting close to the glass. A properly sized air source heat pump offers efficient heating & cooling, and includes a carefully designed the duct distribution system to provide even comfort throughout the house. The super-insulated envelope allows us to significantly reduce the equipment capacity, duct size, and airflow quantities, while maintaining unparalleled thermal comfort.
ENERGY EFFICIENT. The building’s shell and mechanical systems play instrumental roles in the home’s exceptional performance. The building enclosure reduces the most significant energy glutton: heating. Continuous super-insulation, thorough air sealing, triple-pane windows, and passive solar gain work together to yield a miniscule heating load. All active energy consumers are extremely efficient: an air source heat pump for heating and cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation (ERV), and high efficiency appliances. The result is a home that uses 70% less energy than a similar new home built to code requirements.
OVERALL. The home embodies the owners’ goals and values while comprehensively enabling thermal comfort, energy efficiency, a vacation respite, and supplementary income.
