Students from the Piet Zwart Institute in Rotterdam designed “brick biotopes,” made from plaster and sand, which serve dual functions:
1) as bricks, and 2) as a home for house sparrows, which often nest in cracks.
During the past 20 or so years, sparrow populations have declined in many European urban environments. The hand-crafted bricks’ design allows plants and wildlife to “co-exist with architecture.”
This video shows how they’re made.
