We're 13 and 10 and have been building with Rokenbok since we were 6 and 3. We've been adding to our collection over the years and now have a fairly large amount. Our mom thinks we have too much, but there is always something else we want to get.
For this build, we decided to do something different and construct a bookshelf/storage unit, all made out of Rokenbok pieces. The top shelf is useful for holding our controllers and base unit; the middle shelf is tall enough to hold our books or could also be used to store additional Rokenbok vehicles. The bottom shelf has two sliding compartments that pull out so you can access your vehicles, or whatever else you have stored there. It has wheels on the bottom so you can move it around your room.
