Kentuck Knob
Chalk Hill
Pennsylvania 15421-0305

Frank Lloyd Wright 1954

Kentuck Knob is a light and attractive family home, easier to imagine living in than Wright's nearby Fallingwater. The house is undoubtedly esoteric: it is built on a hexagonal grid, with 60 degree angles pervading everywhere (except for the bathrooms, where the square corners to accommodate the baths are the only right angles in the house). The hexagonal theme generates interesting rooms without feeling as gimmicky as it sounds.

The low, expansive roof is largely cantilevered from a strong stone core built around the hexagonal kitchen. Spared of their supporting role, the walls stop short of the roof, the gap filled in much of the house by a wooden ventilation screen with unglazed holes cut in abstract geometric shapes.

The house is built entirely of tidewater red cypress and native fieldstone. Walls of continuous glazing, the ventilation screen described above, and a large 'invisible' window in the sitting room, break down the barriers between inside the house and out. The sitting room's large window is a single sheet of glass set directly in the stone surround, with a matching (and appearing to be continuous) moss garden on each side of the glass.

Unlike the larger Fallingwater, there is no child care center - but there is a sculpture garden for entertainment. The house is a short ride by courtesy bus up the hill from the visitor center; you can go down again by bus, or walk on a good path through woods, a meadow and the sculpture garden.
