Pillow room: don't spend money on couches or lounge chairs and buy a really nice movie screen. (This would be really fun for movie night, to just move all the living room furniture and bring out the pillows!
Skylight through the tin roof.oh man! Above bed oversized skylight- I would love looking up at the stars every night and the rain/thunderstorms would be amazing. add a remote-controlled shade for morning and it would be perfect.
