HOW TO TURN IKEA BOOKSHELVES INTO BUILT-INSI used four 31″ wide white Billy bookshelves and three 15 3/4″ wide white Billy bookshelves. Start by removing the back of the bookshelves.
ADD WOOD TO ENCASE YOUR BOOKSHELVESCover the open space between the ends of the bookshelves and the walls to make this a true wall-to-wall built-in. Nail them into a stud if possible.
