I made this dog house out of shiplap cladding that was left over from the build of my workshop. I sold this dog house on eBay to someone who lives locally, and I even got to meet the dog who would be using it which was a wonderful experience.
Here's a little shelf I made in an alcove next to my bedroom. The shelf sits on top of some brackets that sit on top of the radiator so there are no fixings in to the wall.
