This is a “right-sized” new home, designed by TBDA in Oak Park, IL. While its space planning and technology are entirely 21st-century, its form echoes the scale and detailing of its bungalow and foursquare neighbors. Indoor-outdoor experience is optimized with a front screened porch, complete with a wood-burning fireplace. This house LEED for Homes Platinum and pre-certified Passive House through the Passive House Institute US PHIUS+2015 program. In addition to the efficiency, durability, and inherent air quality that result from Passive House design and building methods, we have strictly controlled adhesives, caulks, sealants, and paints to minimize VOCs, and have used no-added-formaldehyde cabinetry and insulation. We engage a third party air quality testing agency at the end of construction to provide a report on air quality. The house that was on this lot was deconstructed and some pieces of it were used in this house—a transom window, an old door, and a lot of framing lumber.
