House extensions in Hertford

Extensions are the bulk of what we do, and more of our work is in Hertford than anywhere else. Full-width rear extensions, open-plan kitchens and new shower rooms, taken from footings to finish by our own team rather than passed down a chain of subcontractors. Hertford has several conservation areas, and inside one your permitted development rights are tighter, so it is worth knowing which side of that line your house sits on before you pay for drawings. We will tell you on the free visit, and the planning application, if you need one, goes to East Herts District Council.

Questions people ask us about building in Hertford

The answers below are specific to Hertford. Planning rules are national, but the authority that applies them is local, and yours is East Herts District Council.

Do I need planning permission for an extension in Hertford?

Often not. Most single-storey rear extensions fall under permitted development, which is a set of rights you already have. Hertford has several conservation areas though, and those rights are tighter inside one, so it is worth checking before you pay for drawings. Planning applications here go to East Herts District Council, and we will tell you honestly on the free visit which route your house is on.

Are you actually based in Hertford?

Yes. Our yard is at Belfry House on Bell Lane, and more of our work is in Hertford than anywhere else. It means we are minutes away if something needs looking at, and it means you can ask around about us locally rather than taking our word for it.

Which parts of Hertford do you cover?

All of it, and the villages around it. Bengeo, Brickendon, Hertingfordbury and Chapmore End are all on our regular run. If you are just outside and not sure, ring Scott and ask.
