A uniform and cohesive look adds simplicity to the overall aesthetic, supporting the minimalist design of this boathouse. The A5s is Glo’s slimmest profile, allowing for more glass, less frame, and wider sightlines. The concealed hinge creates a clean interior look while also providing a more energy-efficient air-tight window. The increased performance is also seen in the triple pane glazing used in both series. The windows and doors alike provide a larger continuous thermal break, multiple air seals, high-performance spacers, Low-E glass, and argon filled glazing, with U-values as low as 0.20. Energy efficiency and effortless minimalism create a breathtaking Scandinavian-style remodel.

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.

Wide sweeping windows up to 13’ and full-lite doors were installed throughout the home preserving the unobstructed views from the home. Additionally, four 12’ wide Lift and Slide doors were installed in the living room and dining room. Increased natural light, fewer framing members, and the ability to open the door wide for indoor/outdoor living are just a few of the benefits of such large sliding doors. The rear of the home takes full advantage of the expansive marine landscape with full height windows and doors.
Glo A5h and A5s Series were selected with concealed hinges. The Glo A5h, hidden sash, ensures that operational windows share the same profile thickness as fixed units. A uniform and cohesive look adds simplicity to the overall aesthetic, supporting the minimalist design. The A5s is Glo’s slimmest profile, allowing for more glass, less frame, and wider sight lines. The concealed hinge creates a clean interior look while also providing a more energy efficient air-tight window. The increased performance is also seen in the triple pane glazing used in both series. The windows and doors alike provide a larger continuous thermal break, multiple air seals, high performance spacers, low-e glass, and argon filled glazing, with U-values as low as 0.20.

This 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.

The kitchen in this Passive House-inspired new build combines sleek modern design with cutting-edge energy efficiency. Featuring high-performance appliances, custom millwork, and sustainable materials, it offers a functional yet stylish space. Thoughtfully designed for comfort and durability, the kitchen includes optimized lighting, excellent air quality, and precision craftsmanship to complement the home's eco-friendly ethos.

Solar systems are at an all time low and the state and federal governments are offering a number of programs to help you install solar systems on your house. Once the solar systems are installed, you’ll will not only save a lot of money from the hefty electric bills in Los Angeles but your home’s value will also increase.

A properly insulated property will prevent the flow of heat from the property or into the property because heat tends to naturally flow into cooler areas. We are committed to helping both residential and commercial building owners in Los Angeles achieve excellent insulation for their properties.

This LEED Platinum certified house reflects the homeowner's desire for an exceptionally healthy and comfortable living environment, within a traditional neighborhood.
INFILL SITE. The family, who moved from another area of Wellesley, sought out this property to be within walking distance of the high school and downtown area. An existing structure on the tight lot was removed to make way for the new home. 84% of the construction waste, from both the previous structure and the new home, was diverted from a landfill. ZED designed to preserve the existing mature trees on the perimeter of the property to minimize site impacts, and to maintain the character of the neighborhood as well as privacy on the site.
EXTERIOR EXPRESSION. The street facade of the home relates to the local New England vernacular. The rear uses contemporary language, a nod to the family’s Californian roots, to incorporate a roof deck, solar panels, outdoor living space, and the backyard swimming pool. ZED’s careful planning avoided to the need to face the garage doors towards the street, a common syndrome of a narrow lot.
THOUGHTFUL SPACE. Homes with dual entries can often result in duplicate and unused spaces. In this home, the everyday and formal entry areas are one and the same; the front and garage doors share the entry program of coat closets, mudroom storage with bench for removing your shoes, and a laundry room with generous closets for the children's sporting equipment. The entry area leads directly to the living space, encompassing the kitchen, dining and sitting area areas in an L-shaped open plan arrangement. The kitchen is placed at the south-west corner of the space to allow for a strong connection to the dining, sitting and outdoor living spaces. A fire pit on the deck satisfies the family’s desire for an open flame while a sealed gas fireplace is used indoors - ZED’s preference after omitting gas burning appliances completely from an airtight home. A small study, with a window seat, is conveniently located just off of the living space. A first floor guest bedroom includes an accessible bathroom for aging visitors and can be used as a master suite to accommodate aging in place.
HEALTHY LIVING. The client requested a home that was easy to clean and would provide a respite from seasonal allergies and common contaminants that are found in many indoor spaces. ZED selected easy to clean solid surface flooring throughout, provided ample space for cleaning supplies on each floor, and designed a mechanical system with ventilation that provides a constant supply of fresh outdoor air. ZED selected durable materials, finishes, cabinetry, and casework with low or no volatile organic compounds (VOCs) and no added urea formaldehyde.
YEAR-ROUND COMFORT. The home is super insulated and air-tight, paired with high performance triple-paned windows, to ensure it is draft-free throughout the winter (even when in front of the large windows and doors). ZED designed a right-sized heating and cooling system to pair with the thermally improved building enclosure to ensure year-round comfort. The glazing on the home maximizes passive solar gains, and facilitates cross ventilation and daylighting.
ENERGY EFFICIENT. As one of the most energy efficient houses built to date in Wellesley, the home highlights a practical solution for Massachusetts. First, the building enclosure reduces the largest energy requirement for typical houses (heating). Super-insulation, exceptional air sealing, a thermally broken wall assembly, triple pane windows, and passive solar gain combine for a sizable heating load reduction. Second, within the house only efficient systems consume energy. These include an air source heat pump for heating & cooling, a heat pump hot water heater, LED lighting, energy recovery ventilation, and high efficiency appliances. Lastly, photovoltaics provide renewable energy help offset energy consumption. The result is an 89% reduction in energy use compared to a similar brand new home built to code requirements.
RESILIENT. The home will fare well in extreme weather events. During a winter power outage, heat loss will be very slow due to the super-insulated and airtight envelope– taking multiple days to drop to 60 degrees even with no heat source. An engineered drainage system, paired with careful the detailing of the foundation, will help to keep the finished basement dry. A generator will provide full operation of the all-electric house during a power outage.
OVERALL. The home is a reflection of the family goals and an expression of their values, beautifully enabling health, comfort, safety, resilience, and utility, all while respecting the planet.

Located in, Summit Park, Park City UT lies one of the most efficient houses in the country. The Summit Haus – designed and built by Chris Price of PCD+B, is an exploration in design and construction of advanced high performance housing. Seeing a rising demand for sustainable housing along with rising Carbon emissions leading to global warming, this house strives to show that sensible, good design can create spaces adequate for today’s housing demands while adhering to strict standards. The house was designed to meet the very rigid Passiv House rating system – 90% more efficient than a typical home in the area.
The house itself was intended to nestle neatly into the 45 degree sloped site and to take full advantage of the limited solar access and views. The views range from short, highly wooded views to a long corridor out towards the Uinta Mountain range towards the east. The house was designed and built based off Passiv Haus standards, and the framing and ventilation became critical elements to maintain such minimal energy requirements.
