House extensions in St Albans

Extensions and full ground-floor remodels in St Albans. We have done fewer jobs this side of the county than around Hertford, and the ones we have done are full builds rather than patch-ups. Planning here is St Albans City and District Council, which is a different authority from the East Herts one that covers most of our patch, so the local rules are worth checking before anything is drawn up.

What we do in St Albans

ExtensionsExtensions are the bulk of what we do. Over a hundred of them in the last two years, from single-storey rears to full wrap-arounds, built by our own team from the first dig to the last coat.More on extensions

Renovation & RepairWhole-house refurbishments, single rooms, and the repairs people put off. No job is too small to look at.More on renovation & repair

Brickwork & PlasteringThe two trades that decide whether a job looks right. Both are done by our own team rather than subcontracted out.More on brickwork & plastering

Questions people ask us about building in St Albans

The answers below are specific to St Albans. Planning rules are national, but the authority that applies them is local, and yours is St Albans City and District Council.

Do I need planning permission for an extension in St Albans?

It depends on the property, and St Albans is stricter than most of our patch. The city has extensive conservation areas and a lot of listed buildings, and permitted development rights are reduced or removed inside them. Applications go to St Albans City and District Council rather than East Herts. We check which applies before anyone spends money on drawings.

Do you travel to St Albans?

Yes. It is further from the yard than Hertford or Ware, and we take work there anyway. We have run a full extension and ground-floor refurbishment in the city.

Can you do a whole-house refurbishment rather than an extension?

Yes, and in St Albans that is most of what we have done. Internal alterations, knock-throughs, new staircases, kitchens and bathrooms as part of the works, plastering and second fix.
