Michael Bom from Rotterdam, The Netherlands, based Atelier Bomdesign has used old billboards and handles to create these stylish birdhouses. Each ‘Billbirdhouse’ is therefor different and unique. As I love this eco-design trend, I will post more design made from recycled materials later this week. By the way, this week is green week on Emma’s designblogg. So check out Emma’s blog if you like to see more eco-design.
