Hey,
This building could have a door going 3/4 high,and the rest filled with a window with coloured glass.As a house painter I've seen(and painted,1:1!) alot of those here in Belgium and also in The Netherlands.Poorer families not able to have afforded glass would have filled the area above the door with bricks.Alan is right,almost all of the buildings had higher ceilings and were designed for ventilation,hence the height of the ceilings of housing,churches and public buildings in the past;personally i think the scale is ok.
Cheers,Shay
