I am very damaged by university, so my first impression is that balconies were concept that certainly wouldn't be attached to wooden buidlings like that, at least not before the 19th century, when architects got involved in city houses for the burgeois. Also the houses are built very wastefully, each standing freely.

Edit: and mining towns never had wooden framing construction in the first place, because wood was prioritized for mining. This is actually becoming relevant, because he wants to replace wooden houses with stone, but they already should be out of stone. Also calcite mortar exists, he shouldn't need cement.
