Project Update: A Sustainable Family Lake House

OPTI_Brtltt-(5) This energy-efficient lakeside home is designed for an extended family who has been vacationing in New England for generations. The home combines the rustic charm of a New Hampshire cottage with cutting-edge building technology and sustainability.

At around 3,100 sf, the design requirements were to blend in with the existing Lake House vernacular of the neighborhood and the heavily wooded lot, frame views of the surroundings from inside the house, and fit into the lakeside cottage community in scale, proportion and style. Nestled into trees (carefully preserved during construction), the wood shingle home has a roomy screened-in porch and built-in BBQ—a lake retreat must. The colors and textures of materials reflect the laid-back community and surroundings.

The building has an advanced thermal envelope using prefabricated structural panels, sealed with gasket and tape technology for superior airtightness, moisture control and indoor air quality.

OPTI_BRTLTA2A folding glass wall opens the main living areas to the screened in porch, with lake views and an outdoor gas fireplace and cooking/dining area. One of the three, second-floor bedrooms is a spacious bunkroom accommodating eight or more—all are open to the living/dining area below via a shuttered gallery, retaining the theme of an open gathering space. The kitchen, dining, alcove seating area and great room all have views of the gas-burning, fieldstone fireplace.

Sustainable Building Features:
-Programmable bath fans.
-Multi-zone radiant heating.
-High-efficiency Low E windows.
-Eco-friendly dense-pack cellulose insulation providing R-Values of 35 in the walls and R-44 in the roof.
-No mechanical air conditioning—ceiling fans, window placement and stack effect design provide natural cooling.
-A timber frame constructed of sustainably harvested timbers salvaged from fire or insect-damaged forests.

Texas Prefab Lake House

austin texas lake house 1 An admitted This Old House fanatic, Matt Risinger had grown up watching the PBS television series when, in 1989, a program aired that would change his life. The Wickwire Barn Series—the second time Bensonwood had appeared on the long running home improvement program— featured Tedd Benson and an old barn being converted to a new house: a project Matt had dreamed of building for himself someday. It became the seminal moment in his decision to become the best builder he could be.

Fast forward nearly two-and-a-half decades, and architect Andrew Plumb of award-winning Aamodt / Plumb Architects in Cambridge, Massachusetts, is looking for a builder to help assemble and finish out a highly custom modern timberframe ranch home he designed for a special client he has known for years. The lakeside projectTEXAS PREFAB, expected to approach near Passive House standards, would have an aggressive build schedule of one year, and it needed to come in at a fixed budget—so Andrew knew it had to be done right. His first thought was to call Bensonwood for its expertise in the sustainable fabrication of high performance homes, and his second thought was to call green builder, Matt Risinger, now of Risinger Homes, to say Tedd Benson’s company would be fabricating and installing the home’s shell. With the name “Benson” still fresh in his mind after a quarter century, Matt jumped at the opportunity. The home plan, viewable on the Aamodt / Plumb website, is a interpretation of the Texas Ranch vernacular, with two gabled buildings joined by a light-filled entry hall. Designed for a young family, this prefab home strives to create a relaxed, contemporary feel through the use of natural and reclaimed materials, ample daylighting and a thoughtful relationship to the site.

“We sought to create a warm modern atmosphere through the interplay of simple forms, materials and natural light,” says Plumb. The play of the modern and rustic is achieved through material choices and elemental forms. Japanese (Shou Sugi Ban style) charred wood siding, mesquite and ash flooring, and an oversized FireRock masonry chimney and fireplace add a dramatic touch both inside and out. texas green prefab architects renderingThe light-filled open interior, with its elegant but simple timberframe, richly-finished flooring and high-end fixtures, perfectly complements the striking exterior while framing the surrounding views. Matt Risinger asserts that, “The most sustainable house is a pretty one. Architect-designed houses will be loved and cared for because they are beautiful. Ugly houses will fall into disrepair and be torn down eventually.” fireplaceBeyond the aesthetics, this house was designed to coast through the hot parts of the day with little need for air conditioning. This is achieved through rigorous attention to air sealing and our panelization process using super-insulated walls. All the exterior claddings are installed over a rain-screen air gap. The roof, wood siding and even stucco have an air gap behind them so that the potential for water intrusion over the life of the building is minimized. Risinger installed super-efficient mechanical equipment to make the best possible use of the resources consumed. 95%+ efficiency gas equipment, super high-efficiency AC, Ultra-Aire Split Dehumidifier prevents mold and allows the owners to keep thermostat settings high when the building is unoccupied.YOUTUBE TIMELAPSE IMAGE You can watch Matt Risinger’s YouTube video of the home being assembled here. Once the project is completed and finish photos become available, we will revisit this home to detail its space plan. Stay tuned.
