Well-designed architecture doesn't have to just sit on the ground. It's also for the birds and the trees, which is the idea behind the sculptural installation Spontaneous City in the Tree of Heaven located in London. The outdoor artwork features several hundred bird boxes carefully placed on two Ailanthus Altissima trees, and it aims to provide something that both the public can enjoy and our feathery friends will use. It was commissioned by Up Projects with the houses crafted by Jo Joelson and Bruce Gilchrist, also known as London Fieldworks.
These houses don't look like your typical bird boxes; the tiny sculptures are reminiscent of a beehive and are clustered together along the trunk of a tree. They adhere to its form and travel in the direction of its branches. Their design is meant to reflect the surrounding architecture, which is a combination of Georgian town houses, 1960's social housing, and the World's End Estate that's adjacent to one of the tree's locations.
If you'd like to view Spontaneous City, there are two places in London to do so. Head to Duncan Terrace Gardens in east and Cremorne Gardens in the west and look up.
