This rustic style home on Hartwell Lake was designed and built for the owners to enjoy with family and friends during their active weekend lifestyle. The home was built on a narrow, deep lot that was semi-level on the roadside and steep on the lakeside. The back half of the lot heavily wooded with mature oak and poplar trees reducing the harsh sun’s heat gain on the home. The exterior utilizes fiber cement cedar shake and lap siding complimented by deep brown colors for the windows, soffit, trim and the large square columns. A nice balance of natural earth toned stacked stone rounds out the exterior materials completing the rustic casual lake living. The home 5400 SF is designed and built on thee levels each having a primary focus. The main level creates primary daily living for the owners. This level features an open plan with an entry, stair, dining, kitchen and living areas leading to a large lakeside screened porch. A master suite is privately tucked off its own hallway and allowing it to enjoy the lakeside as well with its own private deck. On the opposite side are two bedrooms, a study and a shared bathroom for each to utilize. An open carport for two vehicles was created with the motor court and connects to the mudroom/utility room giving the owners direct entry into their home. The upper level is for the grand children with an oversized bedroom, bathroom and loft area for play. The lower level is the considered the party level. Its primary feature is an elevated stage for the owner’s band opened to a large seating area, dining and kitchen for viewing and listening with direct access to another screened porch. Flanking each side is a theater and two additional bedrooms and bathrooms. Energy Efficient features include: • The majority of the lower level sunk into the site below grade • 6” thick walls utilizing advanced framing techniques • Foil covered roof sheathing • Extensive use of blown in cellulous • All windows & doors are double paned low E argon filed glass • Tank-less water heaters • Three separate high efficiency HVAC units with programmable thermostats and a fresh air ERV. Lastly the owner requested we make every effort to sound proof the home. Many materials and techniques gave a duel purpose and added to the energy efficiency. These items include: • 2x6 walls with staggered studs • Extensive use if rock wool acoustic batting • Tempered glass in all exterior doors and windows • ¼ thick Mass Loaded Vinyl (MLV) was installed on the top and bottom of the floor trusses and on all lower level walls. The combination of the design and detailing utilizing these specific materials enabled us to achieve a 5 Star Plus Energy Star Certification with a HERS Index Score of 50. This home received a the 2015 Pinnacle Award from the SC Home Builders Association for the “Best Achievement in Energy Efficiency” sponsored by the SC Department Commerce.

Imagine a compact backyard home in Golden that keeps family close but gives everyone space. The Golden ADU sits west of North Table Mountain, offering owners a private retreat so their kids' family can take the main house – all while framing epic Denver views. The owners needed independence with family ties, so we created a unit that balances privacy and proximity. South-facing design captures stunning plains and city sights for daily inspiration. Multi-generational living can feel crowded, but this ADU provides a separate, functional space without sacrificing connection. It handles site limits by maximizing views and light efficiently. The concept mixes sloped roofs and simple boxes for a fresh, modern feel that fits the landscape. A large deck extends the living area outdoors, inviting relaxation amid the scenery. Standard wood framing keeps it durable and budget-friendly, built strong for Colorado's elements. South orientation and big windows bring in passive solar warmth and natural light, reducing energy needs while keeping things cozy. Practical main floor with one bedroom, two baths, office, mudroom, and open kitchen-living – all designed for ease and flow. Completed in 2022, the Golden ADU is a smart solution for family living. It blends privacy, views, and efficiency, creating a peaceful space that strengthens bonds and enhances life in the mountains.

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.

The placement and expanse of the fir windows and sliding doors underscore the water’s proximity. The interior gathering space spills out onto the raised outdoor deck and lap pool overlooking the seawall. Reducing the house’s carbon footprint is another priority, accomplished by generating renewable energy on site. The precise angle of the house on the property is calculated for optimal solar energy production by the rooftop photovoltaic panels and a geothermal system installed under the driveway provides heating and cooling for the house. Due to the fact that the site is located on a floodplain, the ground floor of the house is raised and no basement is allowed. This presents a challenge in terms of carving out enough storage space in the main house that one might normally relegate to a basement. Rooms are efficiently sized and serve multiple functions and storage is built-in wherever possible.

This 3 BR, 3 1/2 bath home allows the owners to live on one level most of the time. The Master Suite is on the main level along with the Living Room, Kitchen, Dining, pantries, Sun Room and service areas. The upper level houses two ample bedrooms while the lower level supports a rec center, media room, wine cellar, shop and full wet bar. Conceived as a Great Room house, the main level is designed as one seamless space that flows onto an ample deck overlooking the rear yard. We also incorporated a variety of green building techniques - photo-voltaic shingles on the roof of the garage to generate a portion of the home's energy, a super insulated building envelope, rain water harvesting, high performance windows and doors, a high efficiency heat pump, low flow bath & kitchen fixtures, Energy Star appliances and LED lighting - that greatly reduced this structure's carbon footprint. All of the strategies amounted to a 30% reduction in the energy consumption in this home relative to comparable structures.
