Just seen this and don't mean to repeat the acolades but that is a brilliant piece of kit.
Out of interest, is the model modular, as in can it be extended? I ask as I am about to buy the Forge World Coaching Inn but would prefer it to be larger and wonder if your model could be expanded?
Also - you mention the roof lifts off, what about the 1st floor i.e. do you build it as 3 pieces - Ground floor, 1st floor and roof?
