I built this on a bit of the garden that we didn't use because it floods. It hold the lawn mower, but the kids have a double bed over it. It is more of a summer house, made from recycled things out of skips and gum tree. All for under ﾣ500.
In side, I have a wall of doors and the other walls are pallets stripped down. It's all from recycled pallets, floor boards from the house which I kept at the bottom of the garden for three years. double glazed glass from gum tree (free). A lot of the materials were left over from an extension I built three years ago. Even the fridge freezer/ TV and radio were free from friends wanting to get red of things. The kids and I have had a few sleep overs in there.
