Architectural projects are often generated through the conception of positive or negative built space, the resultant architecture of course is experienced through both these elements. A wet foam is conceived of as a heterogeneous field, the relationship of figure and void is recast as an active negotiation, an evolving relationship between the pressures of liquid and gas. A programmatic field condition is generated through a convection system encoding the “hot” and “cold” activities on the site from which a configuration of locally bound programmatic aggregates emerges. The character of this foam lattice, with its specific curvature and edge-to-surface relationship is more durable and indeed more dominant than any cellular configuration arising from specific conditions.
