[header] How to build a squirrel house [title] Gather your tools. [step] This is a basic woodwork project and doesn't require anything too elaborate. You'll need a saw (jig-saw if you have one), electric screwdriver, and screws (3-4 dozen). 
If you don't have an electric screwdriver, you could also use a hammer and nails. Screws hold the squirrel house's design more securely than nails.
