How to bridge two families together? The design looks forward in terms of how people live today. The home is an experiment in transparency and solid form; removing borders and edges from outside to inside the house, and to really depict “flowing and endless space”. The house floor plan is derived by pushing and pulling the house’s form to maximize the backyard and minimize the public front yard while welcoming the sun in key rooms by rotating the house 45-degrees to true north. The angular form of the house is a result of the family’s program, the zoning rules, the lot’s attributes, and the sun’s path. We wanted to construct a house that is smart and efficient in terms of construction and energy, both in terms of the building and the user. We could tell a story of how the house is built in terms of the constructability, structure and enclosure, with a nod to Japanese wood construction in the method in which the siding is installed and the exposed interior beams are placed in the double height space. We engineered the house to be smart which not only looks modern but acts modern; every aspect of user control is simplified to a digital touch button, whether lights, shades, blinds, HVAC, communication, audio, video, or security. We developed a planning module based on a 6-foot square room size and a 6-foot wide connector called an interstitial space for hallways, bathrooms, stairs and mechanical, which keeps the rooms pure and uncluttered. The house is 6,200 SF of livable space, plus garage and basement gallery for a total of 9,200 SF. A large formal foyer celebrates the entry and opens up to the living, dining, kitchen and family rooms all focused on the rear garden. The east side of the second floor is the Master wing and a center bridge connects it to the kid’s wing on the west. Second floor terraces and sunscreens provide views and shade in this suburban setting. The playful mathematical grid of the house in the x, y and z axis also extends into the layout of the trees and hard-scapes, all centered on a suburban one-acre lot. Many green attributes were designed into the home; Ipe wood sunscreens and window shades block out unwanted solar gain in summer, but allow winter sun in. Patio door and operable windows provide ample opportunity for natural ventilation throughout the open floor plan. Minimal windows on east and west sides to reduce heat loss in winter and unwanted gains in summer. Open floor plan and large window expanse reduces lighting demands and maximizes available daylight. Skylights provide natural light to the basement rooms. Durable, low-maintenance exterior materials include stone, ipe wood siding and decking, and concrete roof pavers. Design is based on a 2' planning grid to minimize construction waste. Basement foundation walls and slab are highly insulated. FSC-certified walnut wood flooring was used. Light colored concrete roof pavers to reduce cooling loads by as much as 15%. 2x6 framing allows for more insulation and energy savings. Super efficient windows have low-E argon gas filled units, and thermally insulated aluminum frames. Permeable brick and stone pavers reduce the site’s storm-water runoff. Countertops use recycled composite materials. Energy-Star rated furnaces and smart thermostats are located throughout the house to minimize duct runs and avoid energy loss. Energy-Star rated boiler that heats up both radiant floors and domestic hot water. Low-flow toilets and plumbing fixtures are used to conserve water usage. No VOC finish options and direct venting fireplaces maintain a high interior air quality. Smart home system controls lighting, HVAC, and shades to better manage energy use. Plumbing runs through interior walls reducing possibilities of heat loss and freezing problems. A large food pantry was placed next to kitchen to reduce trips to the grocery store. Home office reduces need for automobile transit and associated CO2 footprint. Plan allows for aging in place, with guest suite than can become the master suite, with no need to move as family members mature.

Interactive Construction’s second Passive House shows that it is possible to achieve this high level of energy efficiency in even the tightest of lots. This build challenged the common assumption that you need a lot of south facing windows to achieve the Passive House certification. The relatively small solar gains from the limited southern exposure was made up for with an extremely tight air-barrier, a top of the line HRV, and higher R-values of insulation. To achieve the best indoor air quality, low-VOC products were used in the finishes. Solid Maple flooring was used throughout the upper levels to create a beautiful look without the chemicals found in engineered flooring. Aging-in-place was key to the design, with a central elevator and accessible door sizes and shower access. Smart design can make homes for versatile over their lifespan which reduces the need for costly renovations in the future. Both the indoor and outdoor areas blend to create tranquil and calm-inspiring spaces. What the homeowners had to say: Each area works well for its purpose. We love the stairs and the glass wall that separates the stairs from the living area. We love our windows, doors and skylights which give us so much light.

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.

Oasis in the Desert You can find a whole lot of fun ready for the kids in this fun contemporary play-yard in the dessert. Theme: The overall theme of the play-yard is a blend of creative and active outdoor play that blends with the contemporary styling of this beautiful home. Focus: The overall focus for the design of this amazing play-yard was to provide this family with an outdoor space that would foster an active and creative playtime for their children of various ages. The visual focus of this space is the 15-foot tree placed in the middle of the turf yard. This fantastic structure beacons the children to climb the mini stumps and enjoy the slide or swing happily from the branches all the while creating a touch of whimsical nature not typically found in the desert. Surrounding the tree the play-yard offers an array of activities for these lucky children from the chalkboard walls to create amazing pictures to the custom ball wall to practice their skills, the custom myWall system provides endless options for the kids and parents to keep the space exciting and new. Rock holds easily clip into the wall offering ever changing climbing routes, custom water toys and games can also be adapted to the wall to fit the fun of the day. Storage: The myWall system offers various storage options including shelving, closed cases or hanging baskets all of which can be moved to alternate locations on the wall as the homeowners want to customize the play-yard. Growth: The myWall system is built to grow with the users whether it is with changing taste, updating design or growing children, all the accessories can be moved or replaced while leaving the main frame in place. The materials used throughout the space were chosen for their durability and ability to withstand the harsh conditions for many years. The tree also includes 3 levels of swings offering children of varied ages the chance to swing from the branches. Safety: Safety is of critical concern with any play-yard and a space in the harsh conditions of the desert presented specific concerns which were addressed with light colored materials to reflect the sun and reduce heat buildup and stainless steel hardware was used to avoid rusting. The myWall accessories all use a locking mechanism which allows for easy adjustments but also securely locks the pieces into place once set. The flooring in the treehouse was also textured to eliminate skidding.

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

This early 20th century Indianapolis, IN basement remodel was in desperate need of help. The original and still operating hydronic radiant heating system had its plumbing configured without regard to any other use of the space. Fearful of harming the aged system and the high cost of doing so, these Clients were adamant that the existing system remain intact. Architect Lee Constantine developed a design that maintained the existing heating system while creating "niches" around the perimeter that would conceal the unsightly plumbing. Additionally, by removing free-standing structural supporting posts, amore flexible and inviting space was achieved. Because of an already low ceiling condition, the floor-ceiling structure above was kept exposed, painted and highlighted with indirect lighting to avoid further reducing the ceiling height. Constantine incorporated "clouds" on this ceiling to conceal certain existing components that either were cost prohibitive to relocate or couldn't be relocated. These "clouds"become a "visual element" through their geometry and hidden "indirect" light source rather than an undesirable complication. Now this family entertains frequently in the basement and reports "it doesn't feel like we're in a basement anymore"

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.

Located on a narrow urban infill lot, this single-family residence with attached ADU was fashioned for a food brand designer and restaurateur with an affinity for pre-war Parisian apartments. Use of minimal form and materials, on a cost-conscious budget, was intended to achieve a maximum atmospheric interior result. The daylight filled interior focuses on an easterly, inward facing courtyard through a rhythm of punched openings, western light is introduced for balancing only. The home is classically proportioned with subtle drywall details which recall decorative mouldings. From the primary room the Owner teaches cooking classes, entertains, and samples potential menu items while hosting dinner parties. The walls are adorned with her own paintings (made for her first restaurant with no budget). Health-conscious decisions were made both inside and out, selecting no V.O.C. finishes, wall- board and sheathing which prohibit mold and protective exterior coatings which prevent EMFs from penetrating the building envelope. The home is designed to nurture aging-in-place; maintenance friendly materials and plans for a future solar array will reduce overhead expenses in coming years.

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.

Interactive Construction’s second Passive House shows that it is possible to achieve this high level of energy efficiency in even the tightest of lots. This build challenged the common assumption that you need a lot of south facing windows to achieve the Passive House certification. The relatively small solar gains from the limited southern exposure was made up for with an extremely tight air-barrier, a top of the line HRV, and higher R-values of insulation. To achieve the best indoor air quality, low-VOC products were used in the finishes. Solid Maple flooring was used throughout the upper levels to create a beautiful look without the chemicals found in engineered flooring. Aging-in-place was key to the design, with a central elevator and accessible door sizes and shower access. Smart design can make homes for versatile over their lifespan which reduces the need for costly renovations in the future. Both the indoor and outdoor areas blend to create tranquil and calm-inspiring spaces. What the homeowners had to say: Each area works well for its purpose. We love the stairs and the glass wall that separates the stairs from the living area. We love our windows, doors and skylights which give us so much light.
