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.

ZeroEnergy Design (ZED) created this modern home for a progressive family in the desirable community of Lexington.
Thoughtful Land Connection. The residence is carefully sited on the infill lot so as to create privacy from the road and neighbors, while cultivating a side yard that captures the southern sun. The terraced grade rises to meet the house, allowing for it to maintain a structured connection with the ground while also sitting above the high water table. The elevated outdoor living space maintains a strong connection with the indoor living space, while the stepped edge ties it back to the true ground plane. Siting and outdoor connections were completed by ZED in collaboration with landscape designer Soren Deniord Design Studio.
Exterior Finishes and Solar. The exterior finish materials include a palette of shiplapped wood siding, through-colored fiber cement panels and stucco. A rooftop parapet hides the solar panels above, while a gutter and site drainage system directs rainwater into an irrigation cistern and dry wells that recharge the groundwater.
Cooking, Dining, Living. Inside, the kitchen, fabricated by Henrybuilt, is located between the indoor and outdoor dining areas. The expansive south-facing sliding door opens to seamlessly connect the spaces, using a retractable awning to provide shade during the summer while still admitting the warming winter sun. The indoor living space continues from the dining areas across to the sunken living area, with a view that returns again to the outside through the corner wall of glass.
Accessible Guest Suite. The design of the first level guest suite provides for both aging in place and guests who regularly visit for extended stays. The patio off the north side of the house affords guests their own private outdoor space, and privacy from the neighbor. Similarly, the second level master suite opens to an outdoor private roof deck.
Light and Access. The wide open interior stair with a glass panel rail leads from the top level down to the well insulated basement. The design of the basement, used as an away/play space, addresses the need for both natural light and easy access. In addition to the open stairwell, light is admitted to the north side of the area with a high performance, Passive House (PHI) certified skylight, covering a six by sixteen foot area. On the south side, a unique roof hatch set flush with the deck opens to reveal a glass door at the base of the stairwell which provides additional light and access from the deck above down to the play space.
Energy. Energy consumption is reduced by the high performance building envelope, high efficiency mechanical systems, and then offset with renewable energy. All windows and doors are made of high performance triple paned glass with thermally broken aluminum frames. The exterior wall assembly employs dense pack cellulose in the stud cavity, a continuous air barrier, and four inches exterior rigid foam insulation. The 10kW rooftop solar electric system provides clean energy production. The final air leakage testing yielded 0.6 ACH 50 - an extremely air tight house, a testament to the well-designed details, progress testing and quality construction. When compared to a new house built to code requirements, this home consumes only 19% of the energy.

The original small 2 bedroom dwelling was deconstructed piece by piece, with every element recycled/re-used. The larger, newly built home + studio uses much less energy than the original. In fact, the home and office combined are net zero (the home’s blower door test came in at Passive House levels, though certification was not procured). The transformed home boasts a better functioning layout, increased square footage, and bold accent colors to boot. The multiple level patios book-end the home’s front and rear facades. The added outdoor living with the nearly 13’ sliding doors allows ample natural light into the home. The transom windows create an increased openness with the floor to ceiling glazing. The larger tilt-turn windows throughout the home provide ventilation and open views for the 3-level contemporary home. In addition, the larger overhangs provide increased passive thermal protection from the scattered sunny days. The conglomeration of exterior materials is diverse and playful with dark stained wood, concrete, natural wood finish, and teal horizontal siding. A fearless selection of a bright orange window brings a bold accent to the street-side composition. These elements combined create a dynamic modern design to the inclusive Portland backdrop.

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 800 square-foot guest cottage is located on the footprint of a slightly smaller original cottage that was built three generations ago. With a failing structural system, the existing cottage had a very low sloping roof, did not provide for a lot of natural light and was not energy efficient. Utilizing high performing windows, doors and insulation, a total transformation of the structure occurred. A combination of clapboard and shingle siding, with standout touches of modern elegance, welcomes guests to their cozy retreat.
The cottage consists of the main living area, a small galley style kitchen, master bedroom, bathroom and sleeping loft above. The loft construction was a timber frame system utilizing recycled timbers from the Balsams Resort in northern New Hampshire. The stones for the front steps and hearth of the fireplace came from the existing cottage’s granite chimney. Stylistically, the design is a mix of both a “Cottage” style of architecture with some clean and simple “Tech” style features, such as the air-craft cable and metal railing system. The color red was used as a highlight feature, accentuated on the shed dormer window exterior frames, the vintage looking range, the sliding doors and other interior elements.

Conceived as a remodel and addition, the final design iteration for this home is uniquely multifaceted. Structural considerations required a more extensive tear down, however the clients wanted the entire remodel design kept intact, essentially recreating much of the existing home. The overall floor plan design centers on maximizing the views, while extensive glazing is carefully placed to frame and enhance them. The residence opens up to the outdoor living and views from multiple spaces and visually connects interior spaces in the inner court. The client, who also specializes in residential interiors, had a vision of ‘transitional’ style for the home, marrying clean and contemporary elements with touches of antique charm. Energy efficient materials along with reclaimed architectural wood details were seamlessly integrated, adding sustainable design elements to this transitional design. The architect and client collaboration strived to achieve modern, clean spaces playfully interjecting rustic elements throughout the home.

The Port Ludlow Residence is a compact, 2400 SF modern house located on a wooded waterfront property at the north end of the Hood Canal, a long, fjord-like arm of western Puget Sound. The house creates a simple glazed living space that opens up to become a front porch to the beautiful Hood Canal.
The east-facing house is sited along a high bank, with a wonderful view of the water. The main living volume is completely glazed, with 12-ft. high glass walls facing the view and large, 8-ft.x8-ft. sliding glass doors that open to a slightly raised wood deck, creating a seamless indoor-outdoor space. During the warm summer months, the living area feels like a large, open porch. Anchoring the north end of the living space is a two-story building volume containing several bedrooms and separate his/her office spaces.
The interior finishes are simple and elegant, with IPE wood flooring, zebrawood cabinet doors with mahogany end panels, quartz and limestone countertops, and Douglas Fir trim and doors. Exterior materials are completely maintenance-free: metal siding and aluminum windows and doors. The metal siding has an alternating pattern using two different siding profiles.
The house has a number of sustainable or “green” building features, including 2x8 construction (40% greater insulation value); generous glass areas to provide natural lighting and ventilation; large overhangs for sun and rain protection; metal siding (recycled steel) for maximum durability, and a heat pump mechanical system for maximum energy efficiency. Sustainable interior finish materials include wood cabinets, linoleum floors, low-VOC paints, and natural wool carpet.
