I love it!  Will be posting a link to this on my gardening site, 2greenthumbsup.  People are always looking for diy birdhouse plans.

Thank you!

Brilliant!  Great design and great video, I'm Very impressed.  I featured you over at Grassrootsmodern, I hope you don't mind.  I have some extra plywood hanging around, and I think I may have to do this little project.

Be aware that baltic birch plywood may, or may not be weather resistant. The wood itself is fairly weather resistant. The glue on the other can can be a different story.

Plywoods typically use one of two types of glue to bond the multiple layers together.

The more common glue to be used is a urea formaldehyde glue, which is not rated for exterior use. It will stand up to certain amounts of moisture (it stands up to the moisture produced in most bathrooms), but the layers of the plywood will begin to seperate after being exposed to too much moisture.

The other glue typically used is a phenolic resin glue. It is rated for exterior use because of its moisture and heat resistance.

Unless you ask for plywood that has been rated for exterior use, you will almost always get plywood that is only for interior use.
