We bought this for Dd last christmas, Dp decorated the back of the inside with wallpaper courtesy of B&Q, and we bought roof tiled paper and 'parquet (sp) flooring paper from a model shop, Looks absolutely amazing, he painted the outside in yellow with tester pots from homebase. Only downside is the screws that are on the doors so they open fully are small and ours have come off so needed replacing with longer ones!
Dd plays with it for hours!
