Photograph courtesy of Frederick Bruck.One of the earliest displays of Modernist architecture in Maine, Philip Isaacson’s house designed by architect F. Frederick Bruck in 1960 is a perfect 40-foot square box with a flat roof. The square of the house is bracketed front and back with enclosed 20- by 40-foot courtyards. Immaculately maintained and virtually unaltered since 1960, the idiosyncrasies of the house are worn by Isaacson as a badge of honor.
