Hope you get in early! Will pray for it to be so!
As long as you are building, get the carpenter to add a wall of shelves as it is being finished now! A wall of bookshelves with a counter and cabinets below. For "resale" value it could be turned into a library. A good investment now with a later use. Opening under counter for "desk" (sewing center or computer center)! You won't regret it! Think organized. Shelves for books, cabinets for fabric!
