OK, so work had been continuing, despite the lack of updates on the playhouse.
The exterior us just about finished, with just some sort of window shuttering to do. My wife and u settled in not having a door, but we may revisit this decision at a later date.
The outside had been painted (with the assistance from three little ones 8, 5 and 2) a brown colour which to our surprise, has belnded the whole thing into an almost invisible structure - quite a feat for something so big.
Work continues in ernest on cladding the interior to hide the pallets and weather proof the inside, as well as reducing the risk of all those nasty splinters. Any gaps around the roof have been filled in using expanding foam - works a treat.
