What you will need
This diagram from the RSPB website shows measurements for each panel of the wood. Use the first measurement if you are making a small box, and the second if you are building a larger one.
You also need to have a think about what kind of birds you want to attract to your nest box. Starlings and Great Spotted Woodpeckers will need a larger box whereas most other birds will be able to fit nicely into a smaller one.
Different holes will also be suitable for different species. Smaller holes that are 25mm are appropriate for Coal, Marsh and Blue Tit. Great Tit and Tree Sparrow can have a hole of 28mmm or larger and House Sparrow can have a box with a 32mm hole.
