This 5,200 sf eight-story single-family townhouse with 215 sf balconies and 465 sf green roof decks is a former industrial building conversion located in NYC SoHo, completed in 2021. The responsive climate skin cuts annual energy use by 45%; reclaimed timber beams are upcycled into interior fixtures, and wide skylights maximize natural light and ventilation to lower power loads.

A lightweight steel lattice wraps the entire building to enclose balconies and rooftop terraces, while floor-to-floor double-height voids connect functional rooms for unbroken vertical views. Its signature innovation is foldable Tesla slat cladding that passively controls shade, airflow and solar gain: it cools interiors in summer and captures passive solar heat in winter, forming a flexible buffer between private living areas and the public street.
