Yes, as long as you check first which kind of house you've bought. Baldock has a hundred-odd listed buildings and two conservation areas, which is enough heritage to slow some projects down and nowhere near enough to stop the town building. Most homes are post-war. Most extensions start with the ordinary rules. Neighbours apply for permission all the time, and the planning office is kept busy.
Historic England's list has 103 listed buildings in and around Baldock. One is Grade I, eight are Grade II* and 94 are Grade II. Once a building is listed, almost any change that affects its character needs listed building consent, and that covers the inside as well as the outside. Grade II covers most of them. It still means a replacement window becomes a conversation with the council before it becomes an order with a joiner.
The town has two conservation areas, Baldock and Norton. Inside them the council has more say over changes to the outside of a building, and some work that would go ahead elsewhere without an application needs one here. The council's conservation area map shows exactly where each boundary runs, and that is the first thing to look at for any house on a shortlist. Whether a property falls just inside or just outside the line decides how the next five years of improvements go.
Two scheduled monuments lie within the area, including the remains of the Romano-British small town and Late Iron Age settlement at Baldock. Scheduling is the strictest protection there is. It mainly matters to people whose land touches one, and the people living on top of a Roman town have been finding that out for some time.
North Hertfordshire Council received 1,395 planning applications for the area between April 2024 and June 2026, with 672 of them in the most recent twelve months. That is a town of people who bought a house and then set about turning it into a slightly different one. The numbers show how many applied. They don't show how many got what they asked for.
One listed building in the area is on Historic England's Heritage at Risk register. That means its condition is poor enough to draw attention, the kind that brings grant offers and close scrutiny in about equal measure. For the owner of an ordinary house down the road it changes nothing.
For an unlisted house outside the conservation areas, plenty of modest work, such as a rear extension within set limits or a loft conversion, can go ahead as permitted development without a full application. Inside either conservation area, or on any of the 103 listed buildings, assume the work needs consent until the council says otherwise. The same porch can be routine on one street and need a heritage statement two streets away.
Freedom to extend in Baldock is middling. Most homes can be altered without much fuss, and the old core and Norton are where the paperwork starts.
