Yep, that’s a sensible change.
The house name change upon shipping that card should be ‘Townhouse’ (as in Georgian/Victorian Townhouse - one word).
Thematically it would be more fun if the ‘Terraced Houses’ shipment embraced the terraced side by having some benefit for houses being built close to one another (i.e. tiny incremental speeding up of their unlocked settler training), otherwise thematically the shipment name doesn’t really make sense (another suggestion would be to call the shipmenet itself ‘Victorian Housing’ (as it’s arguably available at the in-game age covering the Victorian Era) to broaden it and not specifically Row/Terraced houses.)
Coming back to the Unique Unit/Building and the Brit Manor, Swedes get their unique building look for their house, so it makes sense to add Unique Building artwork for others (also looking at Port’s Feitoria shipment here too!) I’d personally veer towards calling it the Manor (historically a massive house and estate that were not ‘common’) a Cottage instead, as that was the house of the majority of rural British (especially the work force who attended their employer’s Manor). @TheSquidEmpire made an excellent concept mockup British Cottage concept art.
