Inspiration for a large contemporary l-shaped light wood floor and beige floor open concept kitchen remodel in Boston with an undermount sink, flat-panel cabinets, white cabinets, quartzite countertops, blue backsplash, glass sheet backsplash, paneled appliances, an island and white countertops

OVERVIEW Set into a mature Boston area neighborhood, this sophisticated 2900SF home offers efficient use of space, expression through form, and myriad of green features. MULTI-GENERATIONAL LIVING Designed to accommodate three family generations, paired living spaces on the first and second levels are architecturally expressed on the facade by window systems that wrap the front corners of the house. Included are two kitchens, two living areas, an office for two, and two master suites. CURB APPEAL The home includes both modern form and materials, using durable cedar and through-colored fiber cement siding, permeable parking with an electric charging station, and an acrylic overhang to shelter foot traffic from rain. FEATURE STAIR An open stair with resin treads and glass rails winds from the basement to the third floor, channeling natural light through all the home’s levels. LEVEL ONE The first floor kitchen opens to the living and dining space, offering a grand piano and wall of south facing glass. A master suite and private ‘home office for two’ complete the level. LEVEL TWO The second floor includes another open concept living, dining, and kitchen space, with kitchen sink views over the green roof. A full bath, bedroom and reading nook are perfect for the children. LEVEL THREE The third floor provides the second master suite, with separate sink and wardrobe area, plus a private roofdeck. ENERGY The super insulated home features air-tight construction, continuous exterior insulation, and triple-glazed windows. The walls and basement feature foam-free cavity & exterior insulation. On the rooftop, a solar electric system helps offset energy consumption. WATER Cisterns capture stormwater and connect to a drip irrigation system. Inside the home, consumption is limited with high efficiency fixtures and appliances.

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.

A young family with a wooded, triangular lot in Ipswich, Massachusetts wanted to take on a highly creative, organic, and unrushed process in designing their new home. The parents of three boys had contemporary ideas for living, including phasing the construction of different structures over time as the kids grew so they could maximize the options for use on their land. They hoped to build a net zero energy home that would be cozy on the very coldest days of winter, using cost-efficient methods of home building. The house needed to be sited to minimize impact on the land and trees, and it was critical to respect a conservation easement on the south border of the lot. Finally, the design would be contemporary in form and feel, but it would also need to fit into a classic New England context, both in terms of materials used and durability. We were asked to honor the notions of “surprise and delight,” and that inspired everything we designed for the family. The highly unique home consists of a three-story form, composed mostly of bedrooms and baths on the top two floors and a cross axis of shared living spaces on the first level. This axis extends out to an oversized covered porch, open to the south and west. The porch connects to a two-story garage with flex space above, used as a guest house, play room, and yoga studio depending on the day. A floor-to-ceiling ribbon of glass wraps the south and west walls of the lower level, bringing in an abundance of natural light and linking the entire open plan to the yard beyond. The master suite takes up the entire top floor, and includes an outdoor deck with a shower. The middle floor has extra height to accommodate a variety of multi-level play scenarios in the kids’ rooms. Many of the materials used in this house are made from recycled or environmentally friendly content, or they come from local sources. The high performance home has triple glazed windows and all materials, adhesives, and sealants are low toxicity and safe for growing kids. Photographer credit: Irvin Serrano

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.

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. Eric Roth Photo
