Imagine a brick that holds life. The Roost Brick is a hollow brick made for zoological inhabitation and structural capacity. Each brick functions individually as a shelter. When aggregated, the wall of Roost Bricks becomes an ecosystem. Existent forces within the site determine the pattern of aggregation, allowing for ecosystemic adaptation. The bricks not only hold life, but are intended to supply energy through animal material (honey, information, and guano). Each brick has openings that allow the unit to connect or segregate itself to the expanded network of aggregates, allowing for the unexpected cohabitation of local fauna– Homo sapiens included.
