Urban Birds
Around Valentine’s Day courting birds across the UK will begin inspecting potential nesting sites. Informed and inspired by ornithological derives with Peter Holden MBE, 51% studios architecture has planted scores of ‘assisted readymades’ across the Bankside Urban Forest to increase the variety of nesting options open to its urban birds, many of whom are on the endangered list.
We discovered that the standard hollow block used to build some of London’s most celebrated architecture is made from concrete bulked with recycled woodshavings, a material that when used in nestboxes is proven to fledge more young than any other.
Synergistically the interior block dimensions are text book size for house sparrows, radically in decline in the area. Other species designed for are blue tits, great tits, starlings, wrens, robins and blackbirds.

A website, www.urbanbirds.net, launches on Valentine’s Day to allow nesting activity to be tracked by families and bird lovers across the area. Nestworks is a public project and a people’s project, commissioned by the Architecture Foundation as a permanent legacy for the London Festival of Architecture.
