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.
Shoe closets are a dream! I want one so badly. so I can stop wearing the same two pairs of shoes because I'm too lazy to dig through to find the others. Shoes and bags/purses. they require their own closet.
Wooden hangers + shower curtain rings = scarf storage--I've seen this done with the shower curtain rings turned the opposite way and tied to the hanger and then to one another for more vertical storage.
