Meanwhile, the market
Prices rose alongside the building work.
Heritage controls shape what owners can do to their homes, but they have not held back values: the average Maidstone home commanded a county-town price in the latest full year.
Maidstone's planning data tells a clear story. This is a heritage town, defined by listed and conservation controls rather than by any unusual willingness to refuse. Owners adapt protected and period homes within tight rules, Mid Kent approves applications at close to the national rate, and listed-building consent is the constraint to plan around. For anyone buying here, that is the detail to check before you build.
