St Albans is a cathedral city with Roman Verulamium on its doorstep and a street market dating back centuries. Homes in St Albans include Victorian terraces, conservation-area streets, 1930s semis and large detached homes.
Victorian and Edwardian homes often suit side-return extensions and rear-dormer loft conversions, and their solid walls need careful detailing where old meets new. 1930s semi-detached houses are classic candidates for hip-to-gable loft conversions and wraparound rear extensions. Larger detached homes here often suit substantial rear or side extensions, garage conversions and kitchen-diner knock-throughs.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in St Albans can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in St Albans are decided by St Albans City and District Council. Parts of St Albans are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected.
Whatever the planning position, extensions and loft and garage conversions need Building Regulations approval, which covers structure, fire safety, insulation and ventilation. Our guide to planning permission for house extensions explains the limits, and the Planning Portal guide to extensions has interactive examples.
Every project starts with a free visit and a written quote; see how an extension project with us works, step by step.
Choosing builders in St Albans is a big decision, so here is what you get with us:
“They kept on time and on budget. It was a downstairs kitchen bathroom extension so obviously disruptive but made it as easy as possible.”
Yes. St Albans is about 5 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Park Street and Sandridge.
Yes. Side-return extensions are a popular way to widen the kitchen of a Victorian or Edwardian terrace. Some fall under permitted development, but wraparound designs and homes in conservation areas usually need planning permission, and work near the shared wall usually needs a party wall notice.
Usually, yes. Hip-to-gable and rear dormer conversions are common on 1930s semis and are often permitted development within the 50 cubic metre allowance, unless the house is in a conservation area. Building Regulations approval is always needed.
Not always. Many single-storey rear extensions are allowed under permitted development, within limits such as 3 metres deep for an attached house (4 metres for a detached one) and 4 metres high. Parts of St Albans are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in St Albans are decided by St Albans City and District Council. A Lawful Development Certificate gives written confirmation if you're unsure.
Every extension is priced individually, so we give a free, itemised written quote after visiting your home. The main things that move the price are size, the number of storeys, foundations and ground conditions, structural steelwork, glazing, and the kitchen or bathroom fittings you choose.
Councils aim to decide householder planning applications within 8 weeks, and Building Regulations approval can run alongside. Build time depends on size and specification, so we set out a written programme with your quote.
Yes. Our team covers carpentry, bricklaying, roofing, plastering, painting and decorating, and kitchen fitting, and we manage the project from design to completion, so you deal with one firm rather than several contractors.
As well as St Albans, we cover nearby areas such as builders in Park Street, builders in Sandridge, builders in London Colney and builders in Leverstock Green. See every place on our areas we cover page.
