Artist and designer Thomas Dambo (previously) specializes in building family-friendly installations from upcycled materials. One of Dambo’s many interactive projects is Happy City Birds, a ongoing series that lies at the intersection of street art and community development. The Danish artist builds bird houses across urban centers, installing the new homes against buildings, grouped on tall poles, or spaced throughout existing trees.
Since 2006, Dambo and his crew have constructed more than 3,500 birdhouses with recycled wood and paint. Although a large percentage of his works are concentrated in Arken (you can see a Google map of the bird house locations here), many more of them can be found dotting Copenhagen, Aarhus, Odense, Horsens, Beirut, and Berlin. You can see more of Dambo’s bird houses, including this human-size build, and a collection of camoflauged homes, on Dambo’s website.
