What a versatile piece! The room box is 7-1/2" deep x 14-1/2" wide x 9" tall. The walls tabs into the base (and a narrow support around the top).
The back wall and the 2 adjacent to it are all the same width: 5-1/2". The 2 walls closest to the open front are 2-3/4" wide.
Laser-cut from heavy chipboard. Ships flat but a breeze to put together with the slots and tabs precut (you'll just need to secure with a bit of white glue).210328SC GND gryGD 201108NB 201108new 210328SCz
