Over the last 50 years the UK has lost over 44million British Birds, 20million of those are the much loved House Sparrow. Once one of the UK’s most numerous birds, their population has decreased by almost 70%, and they are now classified as endangered.


The causes of this decrease, are thought to be due to a loss in comunal nesting sites, like old buildings, along with the loss of green space in cities, depleting their natural food sources.

Bird Brick provides a nesting site for sparrows, in the form of five traditionally hand-made, clamp-fired bricks. These are installed, in clusters of two or three, into new builds or garden walls to suit communal nesting habits. 

It is not completely necessary for the cavity to be cleaned out as the sparrows will do minor upkeep themselves. However if the homeowner wishes to do so it must be done some time between September and November. The stopper twists out and must then be re-pointed in once the cavity has been cleared.

Each 5 piece unit is comprised of 4 different bricks

The material properties of brick – low thermal and moisture movement and high durability – make the cavity ideal for nesting without affecting the building structurally, as well as being visually unobtrusive.

The Bricks were cast with the help of MBH Freshfield Lane in West Sussex, with whom i worked very closely throughout the project

A five-piece cavity nesting box for new build instillation; designed for the conservation of House Sparrows, and manufactured using a traditional brick-making process.
