Description: My wife and I always wanted a window sill that doubles as a bench. The only problem is that the required wood was to expensive. Then I thought of Gorm, the cheapest shelving unit from Ikea.
I used 8 Gorm 50 cm shelves and 8 height extension posts. First I painted them white using Behandla. I sawed them to a breadth of 35 cm. And used the sides to connect the boards to the window frame.
