Floor to ceiling bookshelves
To make a simple holiday wreath, wrap green florist's wire around the ends of boxwood clippings to form five or six small bunches. Wrap the bunches around a wreath base with more wire so that they overlap. Use the wreaths to decorate shelves and punctuate with jewel-toned ornaments or other trinkets.
Wall in living room where fireplace is now. Convert to wall to wall built-ins (with exception of steps) that wrap into the nook with a computer desk. I like how the sofa is pulled off of it just a bit and could then face the larger part of the room. Another sofa to form an L with tv on front wall. (uses more of the room)
