This house was designed by American architect Robert Gurney and sits in Glen Echo, Md., overlooking the Potomac River. Although it's a new house, it was built on the existing footprint of another home. A reflecting pool was constructed above the actual grade to prevent changing the landscape. It's a boxy structure covered with wood siding, stainless steel and huge walls of windows. The colors and shape blend into the hardwood trees surrounding it, and there are beautiful views from every room, looking like works of art when framed by the black-outlined windows. Inside, there's white terrazzo flooring, white cabinets and aluminum flooring.
In addition to blending into the environment, the house is environmentally friendly. It was built with huge concrete planks, which allow the house to be heated by water. The terrazzo flooring and the concrete foundation also provide passive heating, and the tree canopies overhead keep the house cool in the summer. The owner of the house wanted to work from home, so there's another building with a guest suite and a garage. Its walls are made of Kalwall, a translucent composite material that allows it to be lit entirely by daylight on sunny days.
