Elf house on a tree! That would be cute in the garden, especially in the tree over grown with ivy. How about some battery tea lights in the windows during outdoor parties. I hear the fairies/elves whispering "home school project" in my ear.
Backyard Room or Guest House. The structure has a footprint of just 11 x extra living space to entertain, catch up on work, or just relax by the wood-burning stove. Made with reclaimed vintage wood. This is lovely.
