A Library! We purchase 6 Billy bookcases and 1 Alve corner unit from IKEA on Friday and spent the weekend putting them together. We also got 6 of the height extension units but will need more (we got the last 6). It took most of Saturday to put together the corner unit. By comparison, the shelves just flew together. We will finish them tonight. Then we must figure out the configuration we want and how many more extensions we might need, attach them to the wall and add books.
