The site of Forge Project consists of two structures designed by Ai Weiwei in collaboration with HHF architects. The Tsai residence is the larger of the two buildings and consists of four equal-sized boxes that are built as simple wood construction covered with corrugated metal panels on the outside and wood and gypsum panels on the inside. The floor plan is based on the needs of a traditional house yet organized around the four rigid outboxes.
Parallel to the Tsai residence is a Y-shaped building, constructed of raw, rusted steel. Its upper floor features a circular skylight that illuminates a central art gallery. This residence also houses a fluid living and studio space for Forge fellows.
