My project is a house for sparrows at school, so they don't go hungry or thirsty. They have a plastic trough and feeder, the trough is inside and the trough is outside to attract the birds, under the trough there is a wooden pole for the birds to nest while they eat. In front of the door there is a wooden ramp, so the birds can be nestled in one place, different from the wooden pole that is under the feeder so that other birds can eat while they are poised on the wooden pole.
Inside the wooden house there is cotton to represent the nest.
Everything is hooked with silicone.
I have designed it with inkscape and I have cut the wood with the laser printer.
