This new home is nestled at the end of a quiet street in Takoma Park, Maryland. The lot is surrounded by great Tulip Poplars and historic bungalows. Because of new setbacks on the small site, the original one-story house had to be completely deconstructed.
Left: existing house Right: new design
The design and detail is based on the traditional bungalow. A significant amount of space is deftly contained within pleasing proportions and scale that fit the neighborhood. The house has a full basement, two complete living floors and a sizable attic for storage and kids’ lofts.
Care was taken to create a comfortable and efficient home that is well-knit with the site. Orientation of “winter” and “summer” spaces takes advantage of the path of the sun through the day and seasons, allowing for passive heating and cooling. The sunroom, screened porch, and deck with outdoor shower are in-between spaces from which to engage with the outdoors.
A deep commitment to environmental sustainability informed every aspect of the design and construction. A computer energy model helped the team to coordinate the interactions of the building orientation, envelope, and the mechanical system.
Materials:
The existing house was carefully deconstructed so that salvaged materials could be donated or sold, including brick, framing lumber, oak flooring, paneled doors, kitchen appliances, copper and steel pipe, and aluminum. Even the mercury from the old thermostats was recycled, rather than landfilled. Stone from the original chimney was incorporated into the new house.
85% of the construction waste was recycled.
The concrete has a high percentage of fly-ash, a waste product from coal-fired electricity plants that is usually landfilled. Fly-ash offsets the use of cement, the production of which is highly energy –intensive and contributes to greenhouse gas emissions.
Hardie board siding made from cement and recycled wood fibers; front porch timbers from urban salvaged trees; zero-VOC paint; FSC certified wood floors; bamboo floors; water-based stain and varnish; oak trim from urban salvaged trees (cured in a solar-powered kiln); formaldehyde-free cabinetry; cast concrete & recycled glass counters and soaking tub; LED and fluorescent lighting; interior doors of oak veneer over compressed wheat core.
Energy:
Great attention was paid in the construction to proper insulation of all walls and slabs; and air sealing at joints and openings.
Ceiling fans in all bedrooms, the sunroom, dining room and den are a very low-energy way to stay comfortable during swing seasons.
Heat: High-efficiency “Munchkin” boiler, some rooms have radiant floor heat; Tulikivi ceramic stove in Great Room (a few logs can keep the first floor warm for twelve hours)
Energy Star appliances .
Water:
Plumbing: PEX instead of copper. Low-flush and dual-flush toilets; low-flow faucets and shower heads.
Native plant landscaping.
