This approx. 3,820-square-foot three-bedroom duplex in Tribeca is truly unique. The owner is a fabric designer, painter and sculptor who spent 18 months transforming the space into a highly personalized work of art. The centerpiece of the apartment is a cast-iron and mahogany staircase which was welded together inside the home, backed by an oxidized copper screen crafted by hand. On the upper level of the condo is a column plastered with rusted metals and brass, which took the owner four months to fabricate. The high-ceilinged living room includes exposed wood beams and floor-to-ceiling glass looking over a 900-square-foot landscaped patio with heated limestone flooring panels and a day bed at the foot of a 25-foot sculpture that is framed by concrete columns with back-lit Plexiglas panels, also made by the owner. The master bedroom features walls covered in cotton-satin panels with hand-embroidered silk to resemble a Japanese bamboo garden, and leads into a spa-like en-suite master bathroom. The ideal buyer would be someone who appreciates fine unique art or someone wishing to renovate and make the two-level apartment their own.
