At the back of the dining room area you could put a wall-to-wall bookcase filled with books. If you don't have that many books you can have a display bookcase where you place nick backs, a few books, some magazine, sculptures etc.
I would be in book heaven. One day I'll have not only a home big enough for a room like this, but also enough books to fill the shelves. Well, a girl can dream, can't she? Private library designed by architecture firm Ilai, photography by Lukas Wassmann.
