LOUIS I. KAHN

The Esherick House in Philadelphia, is one of the most studied of the nine built houses designed by American architect Louis Kahn. Commissioned by Margaret Esherick, it was completed in 1961.

The house is noted especially for its spatial organization and for the ventilation and natural lighting provided by its unusual window and shutter configuration. A sunken bathtub doubled as a seat. A kitchen of wood and copper was created for the house by Wharton Esherick, a nationally known craftsman and artist.
