Rather than starting with an outcome in mind, this 1,400 square foot residence began from a polemic place - exploring shared conviction regarding the concentrated power of living with a smaller footprint. From the gabled silhouette to passive ventilation, the home captures the nostalgia for the past with the sustainable practices of the future. While the exterior materials contrast a calm, minimal palette with the sleek lines of the gabled silhouette, the interior spaces embody a playful, artistic spirit. From the hand painted De Gournay wallpaper in the master bath to the rugged texture of the over-grouted limestone and Portuguese cobblestones, the home is an experience that encapsulates the unexpected and the timeless.

Project Goal: Utilize an unfinished story and a half-space to give each daughter a bedroom on the second floor along with a new full bath. Challenge 1: The sloped ceilings in the area presented a challenge to how we could most cost-effectively add a bathroom within building code limits. Solution 1: We’ve come across this challenge often when trying to fit a bathroom in sloped ceiling spaces and the budget or roof doesn't support adding a dormer. In these cases, we built out what we call a "vanity soffit", a tall soffit spanning from higher on the angled portion down to a comfortable height above the faucet bringing the upper portion of the flat wall forward. Its width typically depends on lighting needs and other considerations in the space. The vanity soffit allows the vanity to drop back to the original wall maintaining floor space and clearances while also providing just enough additional height for a practical mirror. For further flexibility, we typically recommend a pivoting mirror. Challenge 2: Homeowners were told the floor structure was sound to finish for living space. Due to the spans, the first-floor ceiling joists did not meet the requirements to be second-floor floor joists. Solution 2: In order to provide a solid base for the new living space, we consulted our engineer. The existing 2x6 members spanned beyond the distance they could while still structurally supporting the new living space floor. We determined throughout most of the space we needed to add in (“sister”) 2 additional 2x6 joists between the existing joists. This additional work also took place during an unseasonably warm spell in June yet we persevered. So proud of our hard-working team.

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.
