Ingenious skylight/ window above the shower! Have your shower under the sun or stars with the comforts of being inside. I wonder if you could open it up to let all the steam escape for no condensation problems.
Just hang this natural bamboo feeder, bait it by adding a few raisins and they will come. It provides them a structural habitat to live on and the raisins provide food after they've cleared the garden of nasty pests. Worth a shot!
