Norman Fisher House

"The house is located on a site which slopes gently down from a main road to small stream. It consists of three cubes, two large ones connected together and a small, separate one. These cubes, together with the existing trees, form two inter-connected outdoor spaces: an entrance court and a kitchen court. Two large cubes, connected diagonally, contain two distinct groups of activities. The first cube contains an entrance lobby and the master bedroom suite with dressing room and bathroom on the first floor and two smaller bedrooms on the second floor. The second cube is connected by a large opening to the entrance lobby. The two-story-high first floor contains the kitchen, and the living areas separated by a free-standing stone fireplace."
— from Heinz Ronner, with Sharad Jhaveri and Alessandro Vasella Louis I. Kahn: Complete Works 1935-74. p181.
