Our client’s goal was to create a small, high-performance, healthy home for herself and her teenage son while providing a place for her father to age in place. An attached private accessory dwelling provides a space for him as well as flexibility in the future. The new home was designed to minimize its footprint on site, made smaller than the original 1930’s house. Embracing adaptability and efficiency, the residence includes two dwellings: a one-bedroom 795 square-foot accessory dwelling at the lower grade and a two-story 1330 square-foot primary dwelling located above. Involved in all aspects of project execution, our client oversaw the process by living in a used trailer parked in the backyard throughout the project’s construction. Family-Share focused on maximizing the footprint’s performance, access to natural light and the health of the occupants. Sustainable features include high-performance glazing, solar preheat for domestic and hot water in-floor heating and reclaimed fir car decking rainscreen siding.

The option to downsize was not an option for the empty nesters who have lived in this home for over twenty-five years. Situated in TMR, the sprawling home has been the venue for many social events, dinner parties and family celebrations. With grown children living abroad, and grand children on the way, it was important that the new kitchen be highly functional and conducive to hosting informal, yet large family gatherings. The kitchen had been relocated to the garage in the late eighties during a large renovation and was looking tired. Eight foot concrete ceilings meant the new materials and design had to create the illusion of height and light. White lacquered doors and integrated fridge panels extend to the ceiling and cast a bright reflection into the room. The teak dining table and chairs were the only elements to preserve from the old kitchen, and influenced the direction of materials to be incorporated into the new design. The island and selected lower cabinetry are made of butternut and oiled in a matte finish that relates to the teak dining set. Oversized tiles on the heated floors resemble soft concrete. The mandate for the second floor included the overhaul of the master ensuite, to create his and hers closets, and a library. Walls were relocated and the floor plan reconfigured to create a luxurious ensuite of dramatic proportions. A walk-in shower, partitioned toilet area, and 18’ vanity are among many details that add visual interest and comfort. Minimal white oak panels wrap around from the bedroom into the ensuite, and integrate two full-height pocket doors in the same material.

The FINNE Svendsen Building is a striking and highly energy-efficient loft building in Seattle’s Fremont neighborhood. The design and building process was unusual, since architect Nils Finne was both designer and builder owner. The client-architect meetings were brief! The building occupies a corner lot, with street facades on the south and west. The two street facades have a nuanced play of light and shadow. The walls of glass and wood are treated as folded planes, with each façade folding back and forth within an overall depth dimension of about 10”. On floors one and three, the large glass panels project forward, while on floor two, the glass is recessed. The pattern on floor two is an inverted version of floors one and three. The wood spandrel panels are custom-milled Western Red Cedar with a blackened stain. The live-work building creates large, open loft spaces on three floors, with high ceilings, huge windows and exposed long-span steel structure. The building can accommodate a range of uses, both present and future. The three floors of the building have 12-ft ceilings and 11-ft high windows with exposed structural steel supports and steel decking ceilings. The floors are clear-span without internal columns interrupting the work space. Mechanical air distribution is limited to the linear core on the northern side of the building, so work areas have clean metal decking ceilings with no ductwork. The building has in-floor radiant heating and cooling, resulting in minimal energy usage. Operating windows are placed strategically throughout the façade, allowing the building to be naturally ventilated in Seattle’s mild climate. The oversized window walls on the south and west also allow natural lighting to penetrate deeply onto the floor plate, keeping lights turned off for much of the daylight hours. A custom sapele wood front door presents a warm contrast to the building’s blackened wood cladding. A delicate screen of wood slats filters light into the main building lobby. The 3-story stair opens directly from the lobby and has been designed to encourage use on a daily basis, keeping elevator usage to a minimum. A three-story glass wall floods the stairwell with natural light, and the all-steel stair floats in the space. Custom-designed perforations in the steel stair railing panels provide unexpected shadow patterns when the late-afternoon sun shines into the stairwell. The building was designed to be a sustainable structure from the start, with 40% higher insulation values than required by code, efficient natural ventilation, large amounts of natural lighting, water-conserving plumbing fixtures, LED lighting, and locally sourced materials. Windows have high-performance Low-E insulated glazing and are equipped with concealed shades. The building roof has been equipped with photovoltaic panels for electrical production, averaging about 850 Kwh per year. The modest initial amount of PV panels will be expanded over time. The radiant hydronic heating and cooling system allows lower operating temperatures and higher occupant comfort levels. The 6” thick concrete slabs for the radiant tubes conserve both heat in the winter and cooling in the summer and provide great comfort for the feet. During the winter months, the radiant heating system keeps overall energy consumption to a very low level. The 9000 SF building costs about $35/month to heat! During the summer, the passive strategies of natural ventilation combine with the radiant slab cooling to minimize air conditioning load. Deep roof overhangs, built-in shades and high operating clerestory windows are also used to reduce heat gain in summer months. During the winter, the lower sun angle is able to penetrate into work spaces and passively warm the concrete floor. Low VOC paints and stains have been used throughout the building. The high level of craft evident in the building reflects another key principle of sustainable design: eschew “throw-away-ism” and make the building last many years!

Madrona Passive House, a new Seattle home designed by SHED Architecture & Design and built by Hammer & Hand, combines contemporary design with high performance building to create an environmentally responsive and resource-efficient house. The home’s airtight, super-insulated building envelope and passive design minimize energy consumption while providing superior thermal comfort to occupants. A heat recovery ventilator supplies constant fresh air to the home’s interior while recovering 90% of thermal energy from exhaust air for reuse inside. A rooftop solar photovoltaic array will provide enough energy to offset most, perhaps all, of the home’s energy consumption on a net annual basis. To manage stormwater the project employs permeable pavers for site hardscape and two cisterns to capture and control rainwater from the home’s roof and the green roof on the garage. By investing in sustainable site development strategies, efficient building systems and an advanced envelope, the project aims to respect the home’s environmentally critical site and achieve one of the world’s most demanding building energy standards: Passive House.

The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction. The wall assembly is combination of six inch Structurally Insulated Panels (SIPs) and 2x6 stick frame construction filled with blown in insulation. The roof assembly is a combination of twelve inch SIPs and 2x12 stick frame construction filled with batt insulation. The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

Photography by Natalie Marotta Bungalows are lovable homes, but how can they be better? Along with many of our clients, we find that older (early 20th c.) homes have a lot of character and a comfortable scale, but are leaky, damp (especially in the basement), have fair to poor air quality, and use unconscionable amounts of fossil fuels to heat. The owners of this bungalow were ready to change that, and wanted to do so with minimal upfront carbon emissions as well. The gut renovation included replacing the basement slab and providing capillary breaks and insulation continuously below grade. The brick structure was treated with a fluid-applied air and water barrier from the interior and insulated entirely with cellulose, a carbon-storing insulation. The roof used HFO-blown spray foam to provide sufficient insulation while allowing headroom for bedrooms, bathrooms, and laundry. One great benefit of a full renovation is the possibility of reconfiguring spaces to suit the family’s lifestyle, and to make the best of indoor-outdoor connections. We opened up the main rooms on the first floor, creating a family gathering spot with a view to the back yard, and a spacious kitchen that supports the family’s commitment to cooking for healthy eating. The stair uses a north-facing skylight to bring light from above into the middle of the home, where it was previously dark. As a decarbonization retrofit, the inefficient furnace was replaced with two small ducted heat pump systems, water heating and clothes drying are powered by air-source heat pumps, and cooking uses an induction cooktop plus electric ovens. Energy recovery ventilation provides filtered fresh air continuous exhaust from the kitchen, baths, and laundry, and supplies fresh, highly filtered air to bedrooms and living spaces. The Better Bungalow now makes sense for the 21st century–it now fits the owners’ life-patterns, is super comfortable, has great air quality, and uses a fraction of the energy it did before, greatly lowering the demand on the utility grid. In the near future, when solar PV is installed, it can achieve net zero or near net zero emissions, and with battery backup, can provide great resilience in the event of power outages.

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.

LEED Certification Level: Platinum. Builder: R & S Engineering & Construction. The Cavanaugh Residence is a contemporary split level with a split personality. Totally designed from the ground up to minimize impact and maximize energy and water efficiency, its beautiful facade belies its hard-working, high-producing systems, earning it a LEED Platinum score of 116.5, and a HERS rating of minus 22. The 2774 square foot home produces over 100 per cent of its power with a 10.8 kw pv system, and captures 100 per cent of its freshwater needs from the curved metal roofs through an engineered collection and purification system, stored in an integrated concrete cistern. Constructed of locally made SIP panels on an infill waterfront lot, the home is oriented to maximize the production of the pv panels. Six inch SIP panels work together with a highly reflective, highly emmisive cool standing seam roof, icynene insulation in ceiling and floors, and carefully placed high efficiency windows and doors to create a tightly sealed environment. The 17-seer Trane heat pump variable speed compressors and TAM 7 air handlers, along with a whole house dehumidifier and fresh air intake provide a comfortable, clean indoor environment while using little energy. In the shoulder seasons, natural ventilation cools the home with fresh breezes drawn from lower windows in each room flowing through the curved ceilings to clerestory windows at the top of the house. Natural daylighting, with windows placed in corners and high clerestories, bounce the abundant natural light so that the owners use the interior LED lighting primarily at night. Windows were sited to frame views of the neighboring park and water, and capture the light, but represent a very low percentage of glazing to wall to conserve energy. Primarily native, xeriscaped turfless landscaping sips reclaimed water from its drip and bubbler irrigiation system, and requires little trimming or chemicals. Established trees, protected during construction, shade the home, FSC certified decks, and yard, providing a cool place to enjoy the outdoors at any time of the day, even in Florida's summer heat. Rainwater is diverted from the bay through the engineered collection and filtration system to an integrated concrete cistern hidden beneath the decks. Abundant Florida rainwater supplies 100 per cent of the home's needs, including drinking, bathing, and cleaning. Naturally soft, the highly filtered and UV purified water requires no chemical treatment or water softener. Coupled with minimal hardscape and permeable drive and walkways, almost all ground water remains on the lot, and out of storm sewers and bay runoffs. Designed as a forever home for this active retired couple, an open floor plan provides diagonal interior views along with great circulation space. Wide hallways and doors, curbless showers, an elevator, and extra blocking in the walls for grab rails insures the couple of being able to use their home even if physical disabilities arise. The home's footprint is minimized by building over the conditioned crawlspace and over-sized garage, and the finished floor height, at least two feet above flood code requirements, significantly reduces insurance costs while maximizing storage space for camping and water sports equipment. Materials, fixtures and appliances were carefully selected for energy and water efficiency, local production where possible, recycled content/recyclability, durability, and cost-effectiveness. The owners were very involved in vetting and materials selections, and assisted in just-in-time purchasing to minimize waste. Scrap materials were sorted daily for re-use elsewhere in the project (blocking, concrete forms, drywall scraps as acoustical insulation in interior walls, etc.), resulting in a tiny waste pile at the end of a dumpster-free project. Concrete waste was hauled to a local recycler to become road base, and extra useable materials were returned to the vendor or donated to Habitat Restore. Cost-effective choices, and careful planning, saved significant dollars in construction cost as well as landfill space. One of the biggest challenges was finding qualified subcontractors who would work within the guidelines. With the help of our LEED consultant and meetings and explanations, most subcontractors not only bought into the ideas readily, but offered up new ideas. Highly skilled and professional, the team of subs, LEED consultant, and contractor proved that LEED construction is excellent construction. The team, the owners, and I also found that LEED construction makes great economic sense. Most materials (other than increased insulation and photovoltaic panels) cost no more, and sometimes less, than those employed in construction of a lesser standard. The owners have been living in the home for a year now, and are thrilled with the results. No power bill. No water bill. Extremely low insurance bill. Minimal ground maintenance. No fabric softener. Reduced use of soap, detergents, and shampoos and cleaning supplies. Less time cleaning with spot-free rainwater. Careful planning and materials selection brought the project in under budget, and the home operates at an extremely low cost, both to the homeowners, and the environment. Who wouldn't be thrilled?

The pairing of SIPs and traditional stick framing allowed for easy air sealing details and a continuous thermal break between the panels and the wall framing. Beyond the building envelope, a number of other high performance strategies were used in constructing this home and ADU such as: battery storage of solar energy, ground source heat pump technology, Heat Recovery Ventilation, LED lighting, and heat pump water heating technology. In addition to the time and energy spent on reaching Passivhaus Standards, thoughtful design and carefully chosen interior finishes coalesce at the Twin Peaks Passive House + ADU into stunning interiors with modern farmhouse appeal. The result is a graceful combination of innovation, durability, and aesthetics that will last for a century to come. Despite the requirements of adhering to some of the most rigorous environmental standards in construction today, the homeowners chose to certify both their main home and their ADU to Passive House Standards. From a meticulously designed building envelope that tested at 0.62 ACH50, to the extensive solar array/ battery bank combination that allows designated circuits to function, uninterrupted for at least 48 hours, the Twin Peaks Passive House has a long list of high performance features that contributed to the completion of this arduous certification process. The ADU was also designed and built with these high standards in mind. Both homes have the same wall and roof assembly ,an HRV, and a Passive House Certified window and doors package. While the main home includes a ground source heat pump that warms both the radiant floors and domestic hot water tank, the more compact ADU is heated with a mini-split ductless heat pump. The end result is a home and ADU built to last, both of which are a testament to owners’ commitment to lessen their impact on the environment.

The Twin Peaks Passive House + ADU was designed and built to remain resilient in the face of natural disasters. Fortunately, the same great building strategies and design that provide resilience also provide a home that is incredibly comfortable and healthy while also visually stunning. This home’s journey began with a desire to design and build a house that meets the rigorous standards of Passive House. Before beginning the design/ construction process, the homeowners had already spent countless hours researching ways to minimize their global climate change footprint. As with any Passive House, a large portion of this research was focused on building envelope design and construction.
