Status Concept
From a close reading of the NYC
Building Code, the concept emerges from the allowance of a single egress if the occupancy is below 6 floors and 2,000 sf/
floor. Paired with a single-keyed elevator, circulation condenses to the center of the lot. Vertical
compression of the egress
staircase increases the number of landings, each leading onto a floor-through apartment, which results in a split-level or shifted section. The resulting tight core supports: access to daylight; preservation of habitable floorspace; flexible unit configurations; and luxuries uncommon to affordable housing.

ECOLOGICAL VERTICAL TRELLIS
The facade concept negotiates competing desires for a contextually appropriate façade and daylight provided through floor-to-ceiling windows.
Without sacrificing interior floor area, the carbon sequestering structural grid concept further provides opportunities to articulate setbacks and
massing since both trellises and balconies are permitted obstructions exempt from zoning.
Eight units are proposed at Passivhaus standards, with highly insulated envelopes and triple-pane glazing with inert gas filling. Built with carbon-sequestered concrete, the structure is a load-bearing frame expressed through the facades as a gridded vertical trellis. Woven with a three-dimensional garden, the vertical trellis integrates rainwater harvesting, hydroponics and on-site solar production to manage stormwater runoff and urban heat island impacts.
