Hi, I will be purchasing the Kidzshack Delightful Shack Kids Wooden Large Cubby House from Bunnings in a few weeks to build it for my 2.5 year old for Christmas. I initially wanted the mud kitchen add-on, but we don't have the space. I still want a little undercover area where he can park his little plastic motorbike he rides around on. The space we have is approximately 340cm W and 350cm L. The cubby and slide extension are apparently 266cm W, leaving me approximately 74cm to work with. Is that enough space to build a little undercover area, or should I give up on the idea?
