Beneath the Water by 'Sergeant Chipmunk'
Firstly presented on Eurobricks, the Modular Old Pharmacy is a great MOC from Thomas with an interesting historical background.
What might look a bit weird at first sight to have the upper floors smaller than the ground floor, has in fact a good explanation. Like Thomas explained here, this was often done in reality in old buildings in Europe because the price of land was so high. By using this architecture trick, you were able to build larger houses on small grounds.
