CHALLENGE The goal of this renovation of and addition to a residential townhouse in SoHo rethought how a building could actively contribute to a more sustainable urban realm.
INNOVATION By adding a large extension onto an existing building with a modest footprint of 19 x 40 feet, we converted the building into an 8-story townhouse for 1 family, wrapped by a spacious lattice envelope functioning as a climatic skin, a third ‘building’.
A glass elevator connects the floors with connective voids that allow for a fluid living environment. The highly recognizable climate envelope, whose spatial and performative properties serve as an adaptable perimeter of the building, is made from a lightweight steel frame and folding panels. This skin can be opened and closed with ease, and adds new exterior spaces in different, variable conditions.
IMPACT The innovative folding envelope modulates exposure to passively regulate internal temperatures, resulting in a total energy savings of up to 45%.
