A new bed for David's room. He asked for a shelf above the bed as well to put books and a clamp reading light above the bed. Maybe extend the end of the bed for extra storage? Might make the bed a bit taller as well to make room for his Lego bins.
galvanized bathroom - perhaps a good outdoor shower idea. I think kids would love this as a circle bath tub/shower(cause lets be honest they want to take baths, but more often than not, need to shower off first:)
