Although the Merchant's House came with a thatch roof and the Town House a tile or slate roof, as both buildings have the same foot print you could swap them around as you please.
I took these shots during WIP to show the interiors. The second floor also lifts out to gain access to the ground floor.
The musketeer shows that the windows are a little low for 28mm, and possibly also 25mm, but perfect for use with 1/72 figures.
For the sake of completing the set as it were, I have ordered two more buildings from Warlord Games. Given that I am still waiting on orders placed in February to arrive from the UK I don't anticipate seeing them too soon...
