Why not get the best of both worlds. Have a base cupboard fitted in the alcove and a bookcase to form an L-shape. We continued the room coving in front of the bookcase to make it look as if the bookcase has always been there. The shaker style base cupboard has three drawers for those DVD and CD’s that you do not want on display. Where the bookcase and base cupboard meets is a space that is accessed through the right hand side door so there is no loss of space. The doors and drawers are on soft closing mechanisms. By hand painting the units in situ, it cuts nicely into the walls and ceiling.
