Tall town house
1 Cut four 30cm planks for the sides, front and back; two 11cm planks for the base and roof; and one 5 x 7cm piece for the middle floor. Screw this to the middle of the two sides.
2 Glue and nail together following the instructions for the basic house. The front piece has two slightly smaller entry holes of 2.5cm as this house will attract smaller birds.
3 If your wood is very wonky and you have large holes, you can plug them with filler, then sand and paint. I painted this house in Annie Sloan Chalk Paint in Emile with dots in Pure.
