As cities grow increasingly crowded microhousing is becoming increasingly popular. So much so that it’s now being offered to the birds in London. Entitled Spontaneous City in the Tree of Heaven, these two sculptural installations are the work of artists Jo Joelson and Bruce Gilchrist, known collectively as London Fieldworks. Several hundred bespoke bird boxes were mounted on two Ailanthus altissima trees, commonly knowns as the tree of heaven.

"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."

Commissioned for the Royal Borough of Kensington and Chelsea and Islington Council by up projects, the installation is meant to be enjoyed by the public as art and put to practical use by the birds. If you’re in London you can check out these pieces in person by visiting Duncan Terrace Gardens in the east and Cremorne Gardens in the west. But if any of the wee houses are currently occupied, you may not want to stand too close. Either that or bring an umbrella.
