Agree with these previous comments! "I like the idea of decorating inside with a Chalkboard (which I have) and some bunting (which I also have). I also like white inside. Since some of the frame is metal, we can consider some magnets?
Playhouse with a deck and sand pit,- would be even better with an extended beam to one side and swings! I love the shaded area and the sand for the kiddos. I'll have to bribe my dad to build one for the babes!
TheRuby cubby is the baby of our cubbies, made for yards or courtyards that are tight for space. Internal size is wide x 1200 deep with a verandah out front. (Total footprint of W x D) Internal height of the cubby is at the roof peak.
Cubby Houses - Castle - Melbourne, Sydney, Brisbane - Package A, Paint it similar colours to our home, paint one inside wall as a black board wall and maybe also build a storage bench seat along one wall for toys etc.
