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.

This lovely little modern farmhouse is located at the base of the foothills in one of Boulder’s most prized neighborhoods. Tucked onto a challenging narrow lot, this inviting and sustainably designed 2400 sf., 4 bedroom home lives much larger than its compact form. The open floor plan and vaulted ceilings of the Great room, kitchen and dining room lead to a beautiful covered back patio and lush, private back yard. These rooms are flooded with natural light and blend a warm Colorado material palette and heavy timber accents with a modern sensibility. A lyrical open-riser steel and wood stair floats above the baby grand in the center of the home and takes you to three bedrooms on the second floor. The Master has a covered balcony with exposed beamwork & warm Beetle-kill pine soffits, framing their million-dollar view of the Flatirons. Its simple and familiar style is a modern twist on a classic farmhouse vernacular. The stone, Hardie board siding and standing seam metal roofing create a resilient and low-maintenance shell. The alley-loaded home has a solar-panel covered garage that was custom designed for the family’s active & athletic lifestyle (aka “lots of toys”). The front yard is a local food & water-wise Master-class, with beautiful rain-chains delivering roof run-off straight to the family garden.

Modern family loft renovation. A young couple starting a family in the city purchased this two story loft in Boston's South End. Built in the 1990's, the loft was ready for updates. ZED transformed the space, creating a fresh new look and greatly increasing its functionality to accommodate an expanding family within an urban setting. Improvement were made to the aesthetics, scale, and functionality for the growing family to enjoy. Photos by Eric Roth. Construction by Ralph S. Osmond Company.

This itty bitty kitchen in a historic Richmond row house had been closed in by unnecessary walls, creating a tight, dysfunctional galley style kitchen with very little storage space. Working alongside our artist and cabinetry making clients, we created a custom design with handmade, custom cabinetry pieces while opening up the kitchen to the dining area, making the space feel exponentially larger. The result is a clean, modern, functional and big energy kitchen.

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

Our Modern Aspen ave. project was a home that grew out of our clients desire to have a modern home in the heart of the art filled, mountain-biking-community of Fruita, Colorado. Our original concept was to renovate an older existing home to be able to better function as a 2-3 bedroom home for her friends and family to come stay, ride bikes, play and enjoy downtown Fruita. Due to a combination of the poor quality of the existing structure, an almost non existent foundation and discovered geotechnical site conditions, the project became a new construction dream getaway. Design Concept: In developing this project our client desired, a modern, open floor plan home filled with natural light and a durable maintenance free exterior. From this program we massed the home into 3 distinctly separate zones contained within 3 simple modern forms; a transitional entry space, the public living spaces and the private bedroom spaces. These zones of the home were each to become visible from the exterior through the use of 3 separate durable exterior material claddings of wood, stucco and steel respectively. Spaces: The entry of the home, clad in wood, was created as a transitional space between the exterior and the living spaces by creating a feeling of compression before entering into the voluminous, light filled, living area. The large volume, tall windows and natural light of the living area allows for light and views to the exterior in all directions. The custom kitchen cabinets and cabinetry storage are “tucked in” under the stairs and loft allowing for a sense of refuge while in the “command center” of the home. In this design every inch of usable space was thoughtfully incorporated into its function. The private bedroom zone of the home has bedrooms stacked on 2 levels with the master suite on the main level and guest bedrooms and guest bath above. These Bedrooms adjoin a loft area that flows onto a covered and well shaded 2nd level deck. The loft and 2nd level deck allows for a separate living space to relax and gather with family and friends. Garage and Exterior landscaping: This project also considered our clients' need for storage and love for travel by creating storage space for an Airstream camper in the oversized 2 car garage at the back of the property. The design of the garage was flat roofed in order to preserve views and light on the north side of the home, while also allowing room for a photovoltaic (PV) solar system to offset electrical needs. The “lawn” and landscaping of the home were designed as a part of a no maintenance exterior requirement. Although wanting to be maintenance as maintenance free as possible on the exterior, her love for dogs required the home to have some form of grass, so we opted for a K-9 Grass turf system that is designed for pets and allows the turf to be rinsed into the soil through the use of a typical sprinkler system. Energy Efficiency: As in all of our homes, we design and built this project with increased energy efficiency standards in mind. Our standards begin below grade by designing our foundations with insulated concrete forms (ICF) for all of our exterior foundation walls, providing the below grade walls with an R value of 23. As a standard, we also install a passive radon system and a heat recovery ventilator to efficiently mitigate the indoor air quality within all of the homes we build. Above grade, the exterior walls on this home are built with 2x6 construction and sheathed with the Zip R-3 system allowing for an air and weather tight, R-27 exterior wall assembly. The flat roofs of the home are insulated with a hybrid closed cell foam and batt insulation system creating an affordable R-45 insulation. These roofs are covered with a reflective white, TPO membrane roof to reflect the excess heat during the hot summer months. The pitched roofs of the home are vented insulated with a breathable R-50 blown fiberglass insulation.

Wood slat elements provide shading from the sun, and the window system is thermally broken; both features work to increase energy efficiency. Wildfire mitigation strategies, crucial for this region, are applied, including landscaping kept away from the house and a 1-hour fire rating construction for the entire building.

Lincoln Farmhouse LEED-H Platinum, Net-Positive Energy OVERVIEW. This LEED Platinum certified modern farmhouse ties into the cultural landscape of Lincoln, Massachusetts - a town known for its rich history, farming traditions, conservation efforts, and visionary architecture. The goal was to design and build a new single family home on 1.8 acres that respects the neighborhood’s agrarian roots, produces more energy than it consumes, and provides the family with flexible spaces to live-play-work-entertain. The resulting 2,800 SF home is proof that families do not need to compromise on style, space or comfort in a highly energy-efficient and healthy home. CONNECTION TO NATURE. The attached garage is ubiquitous in new construction in New England’s cold climate. This home’s barn-inspired garage is intentionally detached from the main dwelling. A covered walkway connects the two structures, creating an intentional connection with the outdoors between auto and home. FUNCTIONAL FLEXIBILITY. With a modest footprint, each space must serve a specific use, but also be flexible for atypical scenarios. The Mudroom serves everyday use for the couple and their children, but is also easy to tidy up to receive guests, eliminating the need for two entries found in most homes. A workspace is conveniently located off the mudroom; it looks out on to the back yard to supervise the children and can be closed off with a sliding door when not in use. The Away Room opens up to the Living Room for everyday use; it can be closed off with its oversized pocket door for secondary use as a guest bedroom with en suite bath. NET POSITIVE ENERGY. The all-electric home consumes 70% less energy than a code-built house, and with measured energy data produces 48% more energy annually than it consumes, making it a 'net positive' home. Thick walls and roofs lack thermal bridging, windows are high performance, triple-glazed, and a continuous air barrier yields minimal leakage (0.27ACH50) making the home among the tightest in the US. Systems include an air source heat pump, an energy recovery ventilator, and a 13.1kW photovoltaic system to offset consumption and support future electric cars. ACTUAL PERFORMANCE. -6.3 kBtu/sf/yr Energy Use Intensity (Actual monitored project data reported for the firm’s 2016 AIA 2030 Commitment. Average single family home is 52.0 kBtu/sf/yr.) o 10,900 kwh total consumption (8.5 kbtu/ft2 EUI) o 16,200 kwh total production o 5,300 kwh net surplus, equivalent to 15,000-25,000 electric car miles per year. 48% net positive. WATER EFFICIENCY. Plumbing fixtures and water closets consume a mere 60% of the federal standard, while high efficiency appliances such as the dishwasher and clothes washer also reduce consumption rates. FOOD PRODUCTION. After clearing all invasive species, apple, pear, peach and cherry trees were planted. Future plans include blueberry, raspberry and strawberry bushes, along with raised beds for vegetable gardening. The house also offers a below ground root cellar, built outside the home's thermal envelope, to gain the passive benefit of long term energy-free food storage. RESILIENCY. The home's ability to weather unforeseen challenges is predictable - it will fare well. The super-insulated envelope means during a winter storm with power outage, heat loss will be slow - taking days to drop to 60 degrees even with no heat source. During normal conditions, reduced energy consumption plus energy production means shelter from the burden of utility costs. Surplus production can power electric cars & appliances. The home exceeds snow & wind structural requirements, plus far surpasses standard construction for long term durability planning.

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.

Wide sweeping windows up to 13’ and full-lite doors were installed throughout the home preserving the unobstructed views from the home. Additionally, four 12’ wide Lift and Slide doors were installed in the living room and dining room. Increased natural light, fewer framing members, and the ability to open the door wide for indoor/outdoor living are just a few of the benefits of such large sliding doors. The rear of the home takes full advantage of the expansive marine landscape with full height windows and doors. Glo A5h and A5s Series were selected with concealed hinges. The Glo A5h, hidden sash, ensures that operational windows share the same profile thickness as fixed units. A uniform and cohesive look adds simplicity to the overall aesthetic, supporting the minimalist design. The A5s is Glo’s slimmest profile, allowing for more glass, less frame, and wider sight lines. The concealed hinge creates a clean interior look while also providing a more energy efficient air-tight window. The increased performance is also seen in the triple pane glazing used in both series. The windows and doors alike provide a larger continuous thermal break, multiple air seals, high performance spacers, low-e glass, and argon filled glazing, with U-values as low as 0.20. Energy efficiency and effortless minimalism creates a breathtaking Scandinavian-style remodel.
