The home on 21 Hycliff Road in Greenwich stands out among its surrounding trees and the sounds of the Byram River with its stark structural glass and steel design. But the mid-century modern home influenced by the design of a former dean of Yale University\u2019s School of Architecture brings the outdoors in through its floor-to-ceiling windows and floating screened porch.\u00a0Originally built in 1957, the house underwent renovations in the mid-1970s by the late architect Paul Rudolph. Rudolph designed the Yale Art and Architecture Building that was completed in 1963, which was later named \u201cRudolph Hall\u201d in 2008, according to Yale News.\u00a0\u00a0Rudolph was appointed the dean of the Yale School of Architecture in 1958, but he left Yale in 1965 to practice his craft in New York City, according to the architect\u2019s website. In addition to designing a number of private residences, some of the projects Rudolph worked on throughout his career include the Embassy for the United States Department of State in Amman, Jordan in 1954, a Cultural Center for the Tuskegee Institute in 1960 and a Macy\u2019s department store in 1980.\u00a0 Rudolph teamed up with the previous owners in the mid-1970s with a goal of adding uniqueness to the home while enhancing the natural qualities. Now on the market for $2.995 million, the home has western facing windows designed to overlook sunsets and the Byram River. The floor-to-ceiling windows around the home give a personalized glimpse of nature.\u00a0Rudolph\u2019s addition included the living room and screened porch with windows on all three sides, according to listing agent Fran Enrlich of Sotheby's International Realty. Steel posts hold up the screened porch to create a hovering effect.\u00a0\u00a0"The creation of the screened porch is truly unique," Enrlich said. "When people walk in, it feels like a treehouse or a place in Northern California. Being in there feels like a sleeping camp you would go to as a kid with the sound of the river below you."\u00a0Outside on the home\u2019s 4.12 acre-lot, there is a heated pool and pool house with two changing rooms. Driving up to the house, the driveway veers off to a two-bedroom apartment above a two-car garage. The front of the house has classic mid-century features including a flat roof, multiple levels and warm tones, according to home design website The Spruce.\u00a0 Inside, the home has four bedrooms and four full bathrooms in its 5,132 square feet of living space. The main bedroom area is connected to the center of the home by a closet-lined hallway, according to the floor plans. The sitting and dining room share a second-level balcony overlooking the river. There\u2019s also a sunken living room off of the dining room that has one of two fireplaces in the home.\u00a0\u00a0There is an additional dining room with sofas and dry bar that is used mostly as a casual coffee-drinking area, according to Enrlich. The informal dining room joins to the double galley kitchen and either side of the kitchen has floor-to-ceiling views.
