My twins share one pretty large room. They are 11 years old now and getting old enough to want more of their own personal space. This 5x5 cubby shelf was perfect to be used as a room divider!
My challenge was that I typically work in the basement, but their room is on the 2nd floor. I didn't have anyone that would be able to help me carry this massive creation up 2 flights of stairs, so I had to build this "on site." Unfortunately, their room is carpeted (poorly), so I brought up some old subfloor panels that I had to have a more flat surface to work on. It wasn't ideal, but made it possible.
It also took me much longer than it would take most people since I was limited to working only during nap times. It probably could have been done in a day or two if I had the opportunity to work continuously.
