What a gorgeous loft-style bedroom. I particularly love the whitewashed exposed brick walls and the low-lying mattress bed. The addition of the slim staircase leading to a tiny dressing space is just gorgeous and such a great use of space.
Reuse an old tree to make a log pathway in your garden. Good use of "yard" trees and other wood that can't be milled; works much better in climates without termites. Good drainage under the log rounds will make the path last longer.
this would actually be a really fun idea to bring light into the space. a ladder could go against the wall where the metal desk is now with string lights. it would be nice to see walking into the room from the hallway
