REK bookcase by Reinier de Jong

Rotterdam-based designer Reinier de Jong has designed an extending bookcase. Update: this project is included in Dezeen Book of Ideas, which is on sale now for £12.


Called REK, the bookcase consists of five parts, which slide out to accommodate books in the resulting voids as the user accumulates them.


"REK is a bookcase that grows with your book collection. The more books, the bigger the bookcase," explains de Jong.


The following information is from the designer:


The zigzag shaped parts slide in and out of each other, providing as much space as needed. With REK there will be no silly sights of half an empty bookcase anymore because REK will always be full. Also with the different spaces that appear you can arrange your books according to their size.


The outside of REK is finished with white high gloss laminate. The inside is finished with another type of laminate, in this case warm grey satin.
