Ordered this for my twin girls for their 3rd birthday. My Dad, other half and brother spent 5 hours constructing it until it was water tight. All were impressed with the quality of the playhouse. My Dad then spent a further 5 hours finishing it off. I bought eco-deck from Amazon for the base to stop it rotting. I think it helped a lot that it was being constructed onto a solid and level patio as the house is very sturdy. My Dad replaced some screws with deck screws and added two pieces of wood to the sides of the roof. The instructions were back to front and it would have been easier if the pieces were labelled. It has not let in any rain and I have added carpet to both levels because the stuff used to preserve the Wood was staining my girls clothes orange (knees etc), I also plan to paint it. My girls love it and it’s definitely good value for money. Very happy with product.
