Hi Apollo,
Good work mate.
I'm a chippy and my kids would of loved a cubby house like that, I never got around to building them one. As per usual, all the gear is under the house to build one with.
I did how-every put an above ground pool in for them a few years ago. Which I knew nothing about at the time
Which still isn't finished yet, needs a deck around the back of it.
Took over 2 months to build, every afternoon it would thunderstorm and fill the deep end up with water. which needed to be dry to pour the concrete mix for the footing and bracing.
