This birdhouse was designed to make a longer lasting home for birds. Current wooden birdhouses usually lasts for five or so years while this one will last for at least thirty or fourty years. The minimalistic design is inspired by functional style of architecture. The outer shell is made out of thin concrete and provides protection and insulation. The door is made of pine and comes in three different colors. The door is hinged in the upper half to be able to clean out old nests. It is fastened around a tree with a nylon strap, that can be easily adjusted. It is available to buy from Skulpturfabriken.
