Dr .Fisher tells an amusing story about the house that Louis Kahn designed for him and his wife in Hatboro, just outside Philadelphia. Soon after its completion, two of Fisher’s new neighbors walked past, pausing for a moment to consider this unusual double-cube structure. One condemned the flat-roofed house made of vertically hung natural wood siding, thinking it out of place in a neighborhood of traditional dwellings of white-painted clapboard and stone. The other reserved judgment. “I’ll wait and offer my opinion,” he declared, “when the thing is uncrated.”
