The box is 250mm x 200mm and 400mm high. The hole diameter is 70mm. The hole itself is a little rough as I don't have a hole saw. I lost mine when I moved here and didn't want to buy a new one for one project. If the nest is a success I might invest in one as I will be wanting to make a variety of other nest types.
Although it doesn't look it in the photo, it is situated about 4m of the ground and faces north east. I remember the first time I put up a nest box in Scotland, I kid you not that within 5 minutes a pair of Blue tits were checking it out. Well I don't expect anything like that in this instance but I will keep and eye on it and if any interest is show I'll post it here.
If anyone's wants to make a nest box then check out Gouldiae's excellent post here or download a pdf file from the Victorian DPI here.
