The exterior displays Webber's eclectic take on traditional Cape Cod style as well as the Lessners' green choices in materials. The roofline's steeply pitched gables and shed overhangs are built with at least 1 foot of overhang, 2 to 3 feet in some places—important for rainfall runoff and house shading as well as aesthetics. The standing-seam metal roof is green because of its durability and also because its factory-applied, highly reflective gray finish keeps the house cool. The ground floor's original brick exterior walls were painted gray-green rather than covered with boards, and the second story is clad in long-lasting, rot-resistant cement-board clapboard and board-and-batten siding. All the windows are energy-efficient, double-insulated, low-e-glass units.
A simple deck made of composite material is a few steps up from the yard. "It's part of green design to include outdoor living spaces," says Linda, who was thrilled to learn that their house received a five-star green rating (the top score) from the city of Austin, which took into account everything from the house's proximity to the grocery store to its use of salvaged doorknobs.
