Klopf Architecture and Outer space Landscape Architects designed a new warm, modern, open, indoor-outdoor home in Los Altos, California. Inspired by mid-century modern homes but looking for something completely new and custom, the owners, a couple with two children, bought an older ranch style home with the intention of replacing it. Created on a grid, the house is designed to be at rest with differentiated spaces for activities; living, playing, cooking, dining and a piano space. The low-sloping gable roof over the great room brings a grand feeling to the space. The clerestory windows at the high sloping roof make the grand space light and airy. Upon entering the house, an open atrium entry in the middle of the house provides light and nature to the great room. The Heath tile wall at the back of the atrium blocks direct view of the rear yard from the entry door for privacy. The bedrooms, bathrooms, play room and the sitting room are under flat wing-like roofs that balance on either side of the low sloping gable roof of the main space. Large sliding glass panels and pocketing glass doors foster openness to the front and back yards. In the front there is a fenced-in play space connected to the play room, creating an indoor-outdoor play space that could change in use over the years. The play room can also be closed off from the great room with a large pocketing door. In the rear, everything opens up to a deck overlooking a pool where the family can come together outdoors. Wood siding travels from exterior to interior, accentuating the indoor-outdoor nature of the house. Where the exterior siding doesn’t come inside, a palette of white oak floors, white walls, walnut cabinetry, and dark window frames ties all the spaces together to create a uniform feeling and flow throughout the house. The custom cabinetry matches the minimal joinery of the rest of the house, a trim-less, minimal appearance. Wood siding was mitered in the corners, including where siding meets the interior drywall. Wall materials were held up off the floor with a minimal reveal. This tight detailing gives a sense of cleanliness to the house. The garage door of the house is completely flush and of the same material as the garage wall, de-emphasizing the garage door and making the street presentation of the house kinder to the neighborhood. The house is akin to a custom, modern-day Eichler home in many ways. Inspired by mid-century modern homes with today’s materials, approaches, standards, and technologies. The goals were to create an indoor-outdoor home that was energy-efficient, light and flexible for young children to grow. This 3,000 square foot, 3 bedroom, 2.5 bathroom new house is located in Los Altos in the heart of the Silicon Valley. Klopf Architecture Project Team: John Klopf, AIA, and Chuang-Ming Liu

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.

Photo credit: Michael Moran/OTTO. We designed this home with a flat roof so that you can barely see the large arrays of PVs (solar panels). If you look very carefully, you can see the outline of the panels above the eaves, but they're almost impossible to spot. The design concept for this home is that you wouldn't see anything on top of the roofs, but the truth is that the photovoltaics contribute significantly to the home's energy efficiency. The home is LEED certified and our clients tell us it's comfortable and cozy throughout the year.

When friends heard that we were planning to build a new home (especially at our time in life) we were regaled with stories of frustration, mistakes, and financial complications. We were convinced it was right to build a small efficient home, so the stories were dismissed with the conviction that we would find the RIGHT general contractor to avoid the pitfalls of home construction. Our decision to use Todd Swanson and Bio-Hab Inc. reflected our desire to use natural, energy efficient materials and systems, to stay small, and to work with a contractor expressing honesty, open-ness, and common sense. We also welcomed his artistic talent in designing and finish work using natural materials -earth plaster,earth floors, wood exteriors and more. We began by working with a designer and Todd in our house design. Todd collaborated with the designer to not only make the design more beautiful and functional, but also practical to construct. We are very pleased with the finished product and love our home. It was easy AND a pleasure to work with Todd. We appreciated his high standard sub contractors and lead men- not only were they professional, they were cheerful to have around! If we were to build again, we would certainly use Todd and his team at Bio-Hab Inc. David and Kay James James Ranch Durango, Colorado

When you first walk into this dressing room, it’s the lighting that jumps out at you first. Each shelf is illuminated to show the brilliant colors and texture of the clothing. Light even pours through the big windows and draws your eye across the rooftops of Brooklyn to see the NYC skyline. It creates a feeling of brightness and positivity that energizes and enlivens. It’s a dressing room where you can look and feel your best as you begin your day. Featured in a modern Italian Melamine and tastefully accented with complementing Matte Nickel hardware and Clear Acrylic handle pulls, this Chic Brooklyn Dressing Room proves to be not only stylish, but functional too. This custom closet combines both high and low hanging sections, which afford you enough room to organize items based on size. This type of mechanism offers more depth than a standard hanging system. The open shelving offers a substantial amount of depth, so you have plenty of space to personalize your room with mementos, collectibles and home decor. Adjustable shelves also give you the freedom to store items of all sizes from large shoe and boot boxes to smaller collectibles and scarves. A functional key to closet design is being able to visualize and conveniently access items. There’s also something very appealing about having your items neatly displayed - especially when it comes to shoes. Our wide shoe shelves were purposely installed on a slant for easy access, allowing you to identify and grab your favorite footwear quickly and easily. A spacious center island provides a place to relax while spreading out accessories and visualizing more possibilities. This center island was designed with extra drawer storage that includes a velvet lined jewelry drawer. Double jewelry drawers can add a sleek and useful dimension to any dressing room. An organized system will prevent tarnishing and with a designated spot for every piece, your jewelry stays organized and in perfect condition. The space is maximized with smart storage features like an Elite Belt Rack and hook as well as Elite Valet Rods and a pull-out mirror. The unit also includes a Deluxe Pant Rack in a Matte Nickel finish. Thanks to the full-extension ball-bearing slides, everything is in complete view. This means you no longer have to waste time desperately hunting for something you know is hiding somewhere in your closet. Lighting played a huge role in the design of this dressing room. In order to make the contents of the closet fully visible, we integrated a combination of energy efficient lighting options, including LED strip lights and touch dimmers as well as under-mounted shelf lights and sensor activated drawer lights. Efficient lighting options will put your wardrobe in full view early in the mornings and in the evenings when dressing rooms are used most. Dressing rooms act as a personal sanctuary for mixing and matching the perfect ensemble. Your closet should cater to your personal needs, whether it’s top shelving or extra boot and hat storage. A well designed space can make dressing much easier - even on rushed mornings.

The new owners were looking forward to living in their new home with an open floor plan, tall vaulted ceilings, and great views. It featured a large Great Room with two big French Doors separating the Dining Room from the Master Bedroom. But after only a few months they identified a major design flaw: Each of the French Doors had ten glass windows with two large windows above each door. (Check out our before and after designs, traffic flow diagrams and photos of this project.) Glass windows and doors allowed sound and light from guests or the TV in the great room to easily sneak into the bedroom. With unique work and sleep schedules (he’s a pilot, she’s a registered nurse) this design wasn’t working. Then there was a traffic flow design flaw: The Master Bedroom had a second entrance from a hallway. To get into the bedroom from the hallway you needed to walk down another claustrophobic hallway. To get from the Master Bedroom to the Master Bath begin at the most remote corner of the bedroom and down a hallway between two closets. Once inside the bath, a huge triangular Jacuzzi dominating the space. So, from a privacy and traffic flow perspective, this home had some major design issues. When Craig Weber first met with the owners, he listened to their ideas and concerns. The owners trusted Craig to come up with the most efficient and most effective solution to this design dilemma. He offered a solution that resolved the bed-bath traffic flow problem, offered some bedroom room privacy, and updated the bath. First, the two French Doors and windows were removed. A new wall was built with sound-absorbing materials, making the Great Room and Dining Room more comfortable spaces for entertaining while creating the bedroom privacy the owners craved. Solving the Bedroom/Bath traffic flow problem began with removing the two existing closets. The bath door was relocated next to the hall entrance, and then a new walk-in closet was added adjacent to the hallway entrance. The solution offered easy access to and from the bath, closet and hallway without a hint of claustrophobia. The Master Bath underwent a major transformation designed for convenience and comfort – especially during long, cold Minnesota winters. Most everything from the former bath was torn out, beginning with the giant Jacuzzi. A new bathtub that is wider and deeper than the standard size was installed with brushed Nickel fixtures. It’s the perfect place to relax with a glass of wine and candles. Warm floors are a Minnesota “must have.” The bath’s new ceramic floor features in-floor electric heat. Getting in and out of the tub is easy and comfortable. The new walk-in shower again features in-floor heating and a place to sit. The most interesting feature of this shower may the custom ceramic tile installed with unique patterns. A new vanity Cambria Bradshaw countertops features two under-hung ceramic sinks with matching brushed Nickel fixtures. Tall ceilings and three glass windows near the ceiling flood the room with natural light. A new energy-efficient window frames an ornamental stained glass window created by the owner’s father – a great personal touch. A quiet place to sleep. A private dining room for entertaining. A Master Bath to die for. And easy traffic flow. The owners couldn’t have been more delighted with the outcome. And Lilly, their cat, loves it too.

Context Norbert and Robin had dreamed of retiring in a Passive House-certified home overlooking the Lubberland Creek Preserve in Southeastern New Hampshire, and they’d done their homework. They were interested in using four integrated Zehnder America (www.zehnderamerica.com) technologies to make the 1,900 square foot home extremely energy efficient. They didn’t miss any opportunity to innovate or raise the bar on sustainable design. Our goals were focused on guaranteeing their comfort in every season, saving them money on a fixed income, and reducing the home’s overall impact on the environment as much as possible. Response The home faces directly south and captures sunlight all winter under tall and vaulted ceilings and a continuous band of slim-lined, Italian triple-pane windows and doors that provide gorgeous views of the wild preserve. A second-story office nook and clerestory provide even deeper views, with a little more privacy. Zehnder, which previously sold its innovative products only in Europe, took on the project as a test house. We designed around Zehnder’s vent-based systems, including a geothermal heat loop that heats and cools incoming air, a heat pump cooling system, electric towel-warmer radiators in the bathrooms, and a highly efficient energy recovery ventilator, which recycles heat and minimizes the need for air conditioning. The house effectively has no conventional heating system—and doesn’t need it. We also looked for efficiencies and smart solutions everywhere, from the lights to the windows to the insulation. The kitchen exhaust hood eliminates, cleans, and recirculates cooking fumes in the home’s unique kitchen, custom-designed to match the ways Norbert likes to prepare meals. There are several countertop heights so they can prep and clean comfortably, and the eat-in kitchen also has two seating heights so people can sit and socialize while they’re working on dinner. An adjacent screened porch greets guests and opens to the view. A roof-mounted solar system helps to ensure that the home generates more energy than it consumes—helped by features such as a heat pump water heater, superinsulation, LED lights and a polished concrete floor that helps regulate indoor temperatures.

This Dining Room is elegant with the plum walls and chandelier. Trying to stay cool in the summer can be a challenge. You may want to give your Air Conditioning system in your home a little help. Your windows are your air conditioners biggest enemy. The solar heat gain coefficient for a standard double pained window can be as high as .76. This means that 76% of the solar heat enters the home through your windows. We work with clients in the Central Indiana Area. Contact us today to get started on your project. 317-273-8343

From the start, we were pleased with the warm welcome and professionalism of the BONE Structure team. We have been very satisfied of our BONE experience. Available and creative, the team has been very responsive to our needs and requests. The schedule was respected and the structure was assembled in record time. The complete construction of our home took less than 4 months and the different tradesmen rapidly understood how efficient their work became with the steel structure with pre-cut openings to receive their materials, like plumbing, electricity, etc. After a full year in our new home, we are able to testify to its strength and energy saving qualities. Nothing has moved, no cracks or construction issues.

This Boulder, Colorado remodel by fuentesdesign demonstrates the possibility of renewal in American suburbs, and Passive House design principles. Once an inefficient single story 1,000 square-foot ranch house with a forced air furnace, has been transformed into a two-story, solar powered 2500 square-foot three bedroom home ready for the next generation. The new design for the home is modern with a sustainable theme, incorporating a palette of natural materials including; reclaimed wood finishes, FSC-certified pine Zola windows and doors, and natural earth and lime plasters that soften the interior and crisp contemporary exterior with a flavor of the west. A Ninety-percent efficient energy recovery fresh air ventilation system provides constant filtered fresh air to every room. The existing interior brick was removed and replaced with insulation. The remaining heating and cooling loads are easily met with the highest degree of comfort via a mini-split heat pump, the peak heat load has been cut by a factor of 4, despite the house doubling in size. During the coldest part of the Colorado winter, a wood stove for ambiance and low carbon back up heat creates a special place in both the living and kitchen area, and upstairs loft. This ultra energy efficient home relies on extremely high levels of insulation, air-tight detailing and construction, and the implementation of high performance, custom made European windows and doors by Zola Windows. Zola’s ThermoPlus Clad line, which boasts R-11 triple glazing and is thermally broken with a layer of patented German Purenit®, was selected for the project. These windows also provide a seamless indoor/outdoor connection, with 9′ wide folding doors from the dining area and a matching 9′ wide custom countertop folding window that opens the kitchen up to a grassy court where mature trees provide shade and extend the living space during the summer months. With air-tight construction, this home meets the Passive House Retrofit (EnerPHit) air-tightness standard of

Our client, with whom we had worked on a number of projects over the years, enlisted our help in transforming her family’s beloved but deteriorating rustic summer retreat, built by her grandparents in the mid-1920’s, into a house that would be livable year-‘round. It had served the family well but needed to be renewed for the decades to come without losing the flavor and patina they were attached to. The house was designed by Ruth Adams, a rare female architect of the day, who also designed in a similar vein a nearby summer colony of Vassar faculty and alumnae. To make Treetop habitable throughout the year, the whole house had to be gutted and insulated. The raw homosote interior wall finishes were replaced with plaster, but all the wood trim was retained and reused, as were all old doors and hardware. The old single-glazed casement windows were restored, and removable storm panels fitted into the existing in-swinging screen frames. New windows were made to match the old ones where new windows were added. This approach was inherently sustainable, making the house energy-efficient while preserving most of the original fabric. Changes to the original design were as seamless as possible, compatible with and enhancing the old character. Some plan modifications were made, and some windows moved around. The existing cave-like recessed entry porch was enclosed as a new book-lined entry hall and a new entry porch added, using posts made from an oak tree on the site. The kitchen and bathrooms are entirely new but in the spirit of the place. All the bookshelves are new. A thoroughly ramshackle garage couldn’t be saved, and we replaced it with a new one built in a compatible style, with a studio above for our client, who is a writer.

We re-worked the floor plan to open up the space in this 1950s ranch, added new high performance windows, an energy efficient fireplace, reclaimed timbers, and lime plaster to completely transform the feel of the space. Photo credit to Mark Bayer Photography.
