Enjoy effortless living with extensive smart home features, including Lutron Caseta dimmers, a Latch smart lock, Nest Protect smoke/carbon monoxide detectors, and Verizon Fios and Spectrum connectivity. A large coat closet, an in-unit Miele washer-dryer and a 42-square-foot cellar storage unit complete this exceptional Park Slope sanctuary.

Timber House boasts a Danish brick facade and columns, beams and floor plates created from a state-of-the-art glue-laminated timber construction process that requires less embodied energy and produces far less waste than other materials.
