The existing house and foundation were not salvageable so preserving the original was not an option. The house is sustainable because it is small. By removing unnecessary rooms and hallways from the plan, less space, volume and surfaces were needed. There is no attic space. The interior utilizes the full volumn to the underside of the roof further reducing the size. The insulation, mechanical systems are fairly standard and meet the current energy codes. Windows were upgraded to reduce solar heat gain.
This new house replaced a small summer cabin on Lake Bloomington. The owners wanted a smaller house than they currently owned. The interior utilizes all of the volume to the underside of the roof, eliminating all attic spaces. This further brought down the size and height of the house. The house is conventionally framed with wood stick members. Exposed steel columns are used to support the center ridge and a steel moment frame is used along the lake side maximizing the glass along the east side. The exterior is clad with vertical cedar siding, horizontal cement siding and Wisconsin limestone. Low solar heat gain windows are used at the large expanses of glass. A steel standing seam roof covers the house. Horizontal wood siding is used inside at the kitchen and cladding a divider wall at the west side of the stair. The stair is an open steel frame with solid wood risers.
