A Greenwich compound with a modernist home designed by Warren Platner is on the market for $4.5 million, as reported by Patch.

The 4.52-acre property at 18 Dwight Lane includes two homes, according to the listing from Brown Harris Stevens. The main residence, built in 1969, is attributed to Platner, an architect and designer whose credits include the Ford Foundation headquarters interiors in New York City and the Windows on the World restaurant at the World Trade Center.

Platner, born in Baltimore in 1919, graduated from Cornell in 1941. He worked in the offices of I. M. Pei and Eero Saarinen, according to Yale University Library's archival records. After Saarinen's death, Platner led interior design for Kevin Roche John Dinkeloo and Associates, collaborating on the Ford Foundation headquarters building. He opened his own firm, Platner Associates, in New Haven in the late 1960s.

His furniture line for Knoll, introduced in 1966, became what the company calls "an icon of modern furniture." Each chair required more than a thousand welds and over one hundred cylindrical steel rods. Platner was inducted into the Interior Design Magazine Hall of Fame in 1985. He died in New Haven in 2006 at age 86.

The Greenwich listing, handled by agent Claudia Smeriglio of Brown Harris Stevens, describes the Platner-designed home as having walls of windows, hardwood and Italian porcelain floors, and a marble-and-onyx primary bath with soaking tub and cedar sauna.

The compound totals five bedrooms, four full bathrooms and one half bath across 6,406 square feet. It sits on a cul-de-sac lot with pond frontage in the North Parkway area.

A second home on the property has three bedrooms and two bathrooms with a Bianco Oro marble bath and glass-railed decks, according to the listing. The grounds include a heated pool, pool bar, cabana, gazebos, bluestone terraces and four fireplaces. Annual taxes are listed at $26,935.

Platner's professional archive, spanning 326.5 linear feet of drawings, photographs and job files, is housed at Yale University's Manuscripts and Archives. The collection documents projects including Windows on the World, Water Tower Place in Chicago and the Kent Memorial Library in Suffield, Connecticut.

The property is listed through Brown Harris Stevens with a five-car garage and RA-4 zoning.
