If youre passionate about mid-century modern architecture, then welcome to this 1950s classic, located in the coveted Western Section of Princeton. Originally a single-story, designed by architect Geoffrey Lawford, the current owners substantially expanded the footprint with two additions, in the 1990s and in the 2000s. Clean lines, muted curves, high ceilings and large windows add to the interior design based on functionality with an open floor plan where indoor and outdoor spaces converge. First floor living begins at a wide entrance hall which leads to an expansive living and dining area with high beam ceilings and walls of glass that showcase that outdoor pergola covered patio and grounds. An adjacent family room separated by glass doors was part of the 1990s addition that also includes a fourth bedroom, a third full bathroom, mudroom, laundry area and a spiral staircase to a lofty study with access to an open-air balcony. A spectacular kitchen addition and renovation by Tobias Design in the mid 2000s, continued the elevated ceiling theme this time with a modern coffer design enhanced by perfectly placed square windows above and tall windows in the breakfast room below. A center island with built-in bookshelves is flanked by floor-to-ceiling maple cabinets, soapstone counters and stainless steel appliances. The bedroom wing to the left of the entrance hall has two bedrooms that share a full hall bathroom and a primary suite with a private full bathroom. The property also boasts a creative history with frequent visits by William Faulkner, who wrote a portion of the novel A Fable, in one of the bedrooms and Albert Einstein who played sonatas with the concert pianist homeowner in the living room. Walking distance to town, the university, restaurants, the theater and so much more. (The property is accessed by Allison Drive, a private one-way street at the corner of Elm.)
