If you look at my etchings: https://www.wimvandermeij.nl/index.php?PageID=226 you’ll see my recent etching of the Zutphen Townhall from the outside, tegether with its 18th century counterpart. Here is part of the inside, and it is easy to see that the architect included a few old houses into the new structure. The brick walls you see here are on the ‘inside’ now; they used to be outer walls.
