DIY Swift box designs

There is a wide range of commercially available Swift boxes, but for those who like DIY, here are some possible designs. All of the designs listed here are suitable for installation externally. None of the carpentry required is particularly advanced, though it helps to have some power tools such as a jigsaw, mitre saw and skill saw. We would also recommend that you visit these Dutch swift box designs and Bristol Swifts nest box designs.

Note, that in some of these posts, we recommend an entrance size of 30mm x 65-75mm. As Starlings can squeeze into a 30mm slot, we now recommend an oblong or obround entrance 28mm x 65-75mm.

The Model 30
This box is suitable for any location as it has a double thickness, waterproof roof (made of uPVC). The 30° sloping roof should deter predators.
