Next-Door Labor

Of the 49 acres that make up the New Canaan, Connecticut, enclave of architect Philip Johnson, 1,815 square feet belong to his Glass House. The rest of the compound, added after 1949, is an architectural laboratory comprising 13 multifarious buildings, like the Sculpture Gallery, a skylighted showcase for Johnson’s art collection, which he briefly considered making his home once it was finished in 1970.
