PRO UK Rendered Build-In Swift Box

Swifts in the UK have been declining rapidly over the past decades. It is believed that the destruction of suitable nesting habitat is a primary reason for this decline, and many councils are now recommending the use of swift bricks in new builds and renovations. 

The Swift built-in nest box is expertly designed to match UK standard brick dimensions—equivalent to the height of two brick courses and the length of two standard bricks. This thoughtful sizing minimizes or eliminates the need to cut bricks during installation, ensuring easy integration into new or existing brickwork.

Manufactured from durable WoodStone®, a sustainable blend of wood fibre and concrete, the Swift built-in next box offers long-lasting performance and excellent insulation properties. The entrance hole extends 20mm beyond the wall surface, simplifying the rendering process and leaving only a clean, round entrance with a slotted opening visible. The box contains two internal nest pans and features a centrally positioned entrance hole, allowing it to be installed either way up. Swifts are colony breeders, so it is recommended that multiple boxes be sited together - just be sure to leave at least 40cm distance between entrance holes. 

The nest box does not require cleaning. Swifts themselves will remove excess nesting material (for example, if a house sparrow has been in the nest box).

The WoodStone® material is fire-rated to DIN 4102-B2; the ply timber backing is not rated.
