When looking at the problem of bird populations shrinking in urban areas due to loss of habitat, Nethlerlands-based product designer Klaas Kuiken was struck with the idea of improving a common bird home: residential roofs. In consultation with the Vogelbescherming (the Dutch bird association) Kuiken designed a ceramic birdhouse that adheres to the ubiquitous roof tiles found throughout the country. The house contains a removable basket to aid in maintenance after mating season and is made with materials that can resist extreme cold in the winter. First designed in 2009 the birdhouses have finally gone into production and 100 are now available for sale.
