Set on a narrow hillside lot overlooking the San Francisco Bay in Point Richmond, California, Bay Heirloom is a Mid-Century Modern family home restored, modernized and adapted for contemporary living. Oriented south-southwest toward the Marin Headlands, with views of the Golden Gate Bridge, the residence captures shifting Bay light throughout the day, from fog-muted mornings to vivid, glowing sunsets.
The home was built by Karlyn Neel’s grandfather, the owner of the construction company Flo-Crete, one of the Bay Area’s early concrete pumping firms. Flo-Crete completed the foundation and structural concrete work, with family photographs documenting the original cinderblock walls and pours. The firm also contributed to major regional infrastructure projects, including the Transbay BART tube and Candlestick Park, situating the house within a broader legacy of Bay Area construction. Growing up, Neel spent considerable time in the home, developing an early appreciation for mid-century modern principles. Instead of parting with this family heirloom, she purchased the home from her grandfather’s estate.
While her grandfather continued to live in the Point Richmond house, Neel purchased a Mid-Century Modern residence in Palm Desert. In contrast to the Bay Area’s cool temperatures, salt air, and persistent winds, the desert home is shaped by heat and sun and requires a different material response. A substantial renovation she led there emphasized thermal performance, filtered light, and restrained detailing. The experience later informed the restoration of her Bay Area family home.
What began as a modest Mid-Century Modern update expanded when decades of exposure to marine conditions revealed leaks and significant structural and seismic deficiencies. Neel was determined to honor her grandfather’s perseverance and without hesitation pivoted to a much more intensive project. Addressing these challenges required close coordination between Neel, Klopf Architecture and Kasten Builders, with architectural restraint and construction precision guiding each intervention. Rather than alter the home’s defining features, the project focused on reinforcing the structure from within. Discreet beams were embedded along the rear facade and in an upstairs wall, strengthening the building while maximizing the wall of glass facing the Bay and opening the wall between the kitchen and the living space. These structural interventions allowed the space to open fully to the Bay without visual interruption, with the kitchen repositioned as the social and functional core of an open, continuous living space. The building envelope was updated using weather- and corrosion-resistant materials appropriate to the marine environment.
The house unfolds vertically from the street, beginning with a modest garage level and workshop, with the main living spaces located below. Original slate flooring at the entry was preserved, along with select furnishings and artwork collected by Neel’s grandfather, anchoring the restored interior in its past. A restrained palette of black accents and pale, natural finishes replaces darker wood tones, reinforcing openness and calm. A naturally illuminated stair connects to the lowest level, where a former basement was transformed into a guest suite and family room opening onto a deck. From there, steps lead directly to a small concrete boat ramp at the water’s edge.
Throughout the project, decisions were guided by continuity rather than transformation for its own sake. Lessons drawn from both desert and coastal climates informed a material strategy rooted in performance and restraint. Bay Heirloom stands as a measured evolution of a family house, structurally renewed and carefully modernized, grounded in the discipline and care that first shaped it.

This 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.

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.

Gardening opportunities are sharply defined by the seasons in New England’s variable climate. Our team was tasked with expanding the growing season for Newtonville, Massachusetts homeowners. The clients envisioned a structure that could perform double duty by serving as both a fully functional four season greenhouse as well as a comfortable home extension. The resulting 24’ x 11’ hybrid addition stunningly captures the sun’s rays while keeping the elements at bay.
The project required careful architectural planning. Working in close collaboration with the team at Legault Design LLC of Concord, MA, Sunspace fabricated a custom aluminum framework that complements the home’s existing aesthetic. Our aluminum products have terrific strength-to-weight ratios allowing for slender profile lines that maximize glass areas without sacrificing structural integrity. Aluminum framing is also inherently resistant to the high humidity levels typical of a working greenhouse. This was doubly important given the space’s dual purpose.
Another key to this greenhouse’s performance is found in its glazing. A glass structure intended for year-round habitation demands intelligent thermal management. We outfitted the enclosure with Cardinal Low-E 366 high-performance glass. Cardinal’s 1” thick insulated units, filled with argon gas, act as a crucial thermal barrier. These units also feature a specialized coating blocking 95% of damaging UV rays, enabling them to retain heat in the winter while reflecting it during the summer. The best modern glass technology allows spaces like this one to remain temperate sanctuaries in any environmental condition.
This greenhouse’s design incorporates three expansive 42” x 60” awning windows to encourage natural airflow, and the 10′ folding glass wall system dissolves the boundary between the interior and exterior yard when fully opened. The seamless indoor-outdoor flow is perfect for summer entertaining or simply letting the space breathe. The space is instantly adaptable to the needs of the moment, whether shielding the home from harsh snows or thrown open to invite a summer breeze.

McKeesport Downtown Housing, formerly a YMCA, is an 84-unit SRO for people at risk of homelessness. The old brick and terracotta building was important historically for McKeesport. The decision to design the project to Passive House criteria actually went a long way to making the pro-forma work. This project was the first large scale retrofit to be designed to meet Passive House Standards in the US. Another major concern of the project team was to maintain the historic charm of the building.
Space was at a premium and a reorganization of space allowed for making larger resident rooms. Through a community process with various stakeholders, amenities were identified and added to the project, including a community room, a bike storage area, exterior smoking balconies, single-user rest rooms, a bed bug room for non-toxic treatment of bed bugs, and communal kitchens to provide healthy options for food. The renovation includes new additional lighting, air-conditioning, make-up air and ventilation systems, an elevator, and cooking facilities. A cold-weather shelter, 60-day emergency housing, bridge housing, and section 8 apartment rentals make up the housing programs within the shelter. Thoughtful Balance designed the interiors, and selected the furniture for durability and resistance to bed bugs.
The project team worked closely with Zola Windows to specify a unique uPVC window that not only offers passive house performance levels at an affordable cost, but also harmonizes with the building’s historic aesthetic. Zola’s American Heritage SDH (simulated double hung) from the popular, budget-friendly Thermo uPVC line was specified for the project. The windows implemented in this project feature a lower tilt & turn window and a fixed upper for maximum airtightness and thermal performance. The implementation of these windows helped the project team achieve a very significant energy consumption reduction of at least 75%.

The shell is engineered from high-performance athletic fabric with added benefits of breathability and moisture wicking, fused with technical performance fiber fill. Team up the Pro•Sleep Comforter & Mattress pad with SHEEX® performance sheets to transform your bed into a high-performance zone.

McKeesport Downtown Housing, formerly a YMCA, is an 84-unit SRO for people at risk of homelessness. The old brick and terracotta building was important historically for McKeesport. The decision to design the project to Passive House criteria actually went a long way to making the pro-forma work. This project was the first large scale retrofit to be designed to meet Passive House Standards in the US. Another major concern of the project team was to maintain the historic charm of the building.
Space was at a premium and a reorganization of space allowed for making larger resident rooms. Through a community process with various stakeholders, amenities were identified and added to the project, including a community room, a bike storage area, exterior smoking balconies, single-user rest rooms, a bed bug room for non-toxic treatment of bed bugs, and communal kitchens to provide healthy options for food. The renovation includes new additional lighting, air-conditioning, make-up air and ventilation systems, an elevator, and cooking facilities. A cold-weather shelter, 60-day emergency housing, bridge housing, and section 8 apartment rentals make up the housing programs within the shelter. Thoughtful Balance designed the interiors, and selected the furniture for durability and resistance to bed bugs.
The project team worked closely with Zola Windows to specify a unique uPVC window that not only offers passive house performance levels at an affordable cost, but also harmonizes with the building’s historic aesthetic. Zola’s American Heritage SDH (simulated double hung) from the popular, budget-friendly Thermo uPVC line was specified for the project. The windows implemented in this project feature a lower tilt & turn window and a fixed upper for maximum airtightness and thermal performance. The implementation of these windows helped the project team achieve a very significant energy consumption reduction of at least 75%.

Gardening opportunities are sharply defined by the seasons in New England’s variable climate. Our team was tasked with expanding the growing season for Newtonville, Massachusetts homeowners. The clients envisioned a structure that could perform double duty by serving as both a fully functional four season greenhouse as well as a comfortable home extension. The resulting 24’ x 11’ hybrid addition stunningly captures the sun’s rays while keeping the elements at bay.
The project required careful architectural planning. Working in close collaboration with the team at Legault Design LLC of Concord, MA, Sunspace fabricated a custom aluminum framework that complements the home’s existing aesthetic. Our aluminum products have terrific strength-to-weight ratios allowing for slender profile lines that maximize glass areas without sacrificing structural integrity. Aluminum framing is also inherently resistant to the high humidity levels typical of a working greenhouse. This was doubly important given the space’s dual purpose.
Another key to this greenhouse’s performance is found in its glazing. A glass structure intended for year-round habitation demands intelligent thermal management. We outfitted the enclosure with Cardinal Low-E 366 high-performance glass. Cardinal’s 1” thick insulated units, filled with argon gas, act as a crucial thermal barrier. These units also feature a specialized coating blocking 95% of damaging UV rays, enabling them to retain heat in the winter while reflecting it during the summer. The best modern glass technology allows spaces like this one to remain temperate sanctuaries in any environmental condition.
This greenhouse’s design incorporates three expansive 42” x 60” awning windows to encourage natural airflow, and the 10′ folding glass wall system dissolves the boundary between the interior and exterior yard when fully opened. The seamless indoor-outdoor flow is perfect for summer entertaining or simply letting the space breathe. The space is instantly adaptable to the needs of the moment, whether shielding the home from harsh snows or thrown open to invite a summer breeze.
