Our inspiration for this home was an updated and refined approach to Frank Lloyd Wright’s “Prairie-style”; one that responds well to the harsh Central Texas heat. By DESIGN we achieved soft balanced and glare-free daylighting, comfortable temperatures via passive solar control measures, energy efficiency without reliance on maintenance-intensive Green “gizmos” and lower exterior maintenance. The client’s desire for a healthy, comfortable and fun home to raise a young family and to accommodate extended visitor stays, while being environmentally responsible through “high performance” building attributes, was met. Harmonious response to the site’s micro-climate, excellent Indoor Air Quality, enhanced natural ventilation strategies, and an elegant bug-free semi-outdoor “living room” that connects one to the outdoors are a few examples of the architect’s approach to Green by Design that results in a home that exceeds the expectations of its owners.

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.

The owners of this home came to us with a plan to build a new high-performance home that physically and aesthetically fit on an infill lot in an old well-established neighborhood in Bellingham. The Craftsman exterior detailing, Scandinavian exterior color palette, and timber details help it blend into the older neighborhood. At the same time the clean modern interior allowed their artistic details and displayed artwork take center stage. We started working with the owners and the design team in the later stages of design, sharing our expertise with high-performance building strategies, custom timber details, and construction cost planning. Our team then seamlessly rolled into the construction phase of the project, working with the owners and Michelle, the interior designer until the home was complete. The owners can hardly believe the way it all came together to create a bright, comfortable, and friendly space that highlights their applied details and favorite pieces of art.

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.

The West Town GreenStar Retrofit is a historic landmarked two-flat in Ukranian Village that was converted to an efficient, healthy, and modern single-family home, while keeping interior and exterior historic character details. Special emphasis was put on indoor air quality and indoor-outdoor connections. The design focuses on non-toxic materials, good ventilation, low energy and water use, and the biophilic health advantages of light and views of nature. The kitchen, work, and family zones have views of the sun-filled south garden, an oasis in the urban environment containing native plants and fruit trees, rain garden, vegetable garden, chicken coop, apiary, and a patio. Outdoor connection and daylighting are also optimized through the skylight on the top level which spills light down the staircase. The energy strategy began with thorough retrofit insulation and air sealing, and included high performance windows and doors, solar thermal (hot water) and solar photovoltaic (electricity production) systems which support electric vehicle (EV) charging and high-efficiency smart lighting and appliances. HVAC is supplied by a combination of radiant heat, mini-split heat pumps, and a conditioning energy recovery ventilation system (CERV).

Notice the fun pocket windows along the west-facing wall. They were specifically designed to minimize the amount of glaring western sunlight entering the home and provide snippets of views of the beautiful hillside behind. They serve two other important functions: senses of security and privacy. The homeowners can see from their kitchen and living room small views of the road and who is entering their driveway, but drivers-by cannot see in. The Crimson Bluffs Home is a sustainable smaller home with 360 degree views of the Missouri River and various mountain ranges. Energy-efficiency strategies include long-lasting building materials, passive cooling, ample natural day lighting, high insulation values, advanced framing, and a combined heating approach of passive solar heat gain and radiant hydronic floor heating, a strategy we call “Sun Smart Radiant Heating.” Also notice the tiled radiant hydronic floor soaking up the sun's natural energy on this February 15th day. The passively collected heat is actively distributed throughout the first floor by the radiant floor in a strategy we call "Sun Smart Radiant Heat." Greenovision Home Design

The SIX is a 52-unit affordable housing project provides a home, support services and rehabilitation for disabled veterans. It is located in the MacArthur Park area of Los Angeles. McArthur Park has one of the highest densities in the USA with over 38,000 people per square mile and a total population of 120,000 people in 2.72 square miles. Offering shelter and comfort, the SIX breaks the prescriptive mold of the traditional shelter by creating public and private "zones" in which private space is deemphasized, in favor of large public areas. The organization of the space is intended to transform the way people live-away from a reclusive, isolating layout towards a community-oriented, interactive space. The ground level contains offices, support spaces for the veterans, bike storage and parking while the second level has a large public courtyard. Surrounded by four levels of housing units with balconies wrapped with a wood screen made from recycle planking the courtyard has large openings with green roofs that visually connects the space to the street on the lower level beyond. This allows the tenants to enjoy a secured open space while still connecting to the larger community. The uppermost level has a green roof, large public patio and edible garden with panoramic views of the area. The SIX distinguishes itself from most conventionally developed projects in that it incorporates energy efficient measures that exceed standard practice, optimize building performance, and ensure reduced energy use during all phases of construction and occupancy. The planning and design emerged from close consideration and employment of passive design strategies. These strategies include: locating and orienting the building to control solar cooling loads; shaping and orienting the building for exposure to prevailing winds; shaping the building to induce buoyancy for natural ventilation; designing windows to maximize day lighting; shading south facing windows and minimizing west-facing glazing; designing windows to maximize natural ventilation; utilizing low flow fixtures and storm water management; shaping and planning the interior to enhance daylight and natural air flow distribution. These passive strategies alone make this building 50% more efficient than a conventionally designed structure.

The "secret ingredient" in organic container gardens: worm castings with live worms. Red compost worms convert organic nutrients in potting soils into plant-available form, and the last chamber of the worm gut is loaded with beneficial bacteria and fungi that boost plant immunity, cycle nutrients, and increase the water-holding capacity of the potting soil.

The stairs leading to the bottom floor. The stairs were designed and built by Mark's Lumber of Clancy, MT and were installed by Dan Harrigfeld. The custom welded ties for securing the railing to the stairs were fabricated by a high school student from Townsend High School as part of a shop class assignment. The steel was leftover from the exterior custom awnings (fabricated by Mark Pelletier). Most materials of this home were carefully selected to be either recycled or sustainable/long-lasting.The inclusion of this student into the construction of this home really illustrates how the Crimson Bluffs Home was a community project. Like it takes a village to raise a child, it also takes a village to build a house!
