Building work in Lewsey: what we see locally

Lewsey is a residential area of west Luton, next to Lewsey Park and close to Dunstable. Homes in Lewsey include 1960s and 1970s estate housing.

Post-war houses here often have good-sized gardens and straightforward layouts, which suit single-storey rear extensions and open-plan kitchen-diners.

Do you need planning permission for building work in Lewsey?

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Lewsey can go ahead under permitted development, but the limits are strict and some homes have lost those rights.

Planning applications in Lewsey are decided by Luton Borough Council.

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.

Builders in Lewsey: frequently asked questions

Do you cover Lewsey?

Yes. Lewsey is about 10 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Houghton Regis and Dunstable.

What extensions suit post-war houses in Lewsey?

Single-storey rear extensions for a bigger kitchen-diner are the most common, followed by garage conversions and two-storey side extensions where the plot allows. Post-war houses often have regular layouts and simple roofs, which helps keep the structural work straightforward.

Do I need planning permission for an extension in Lewsey?

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. Applications in Lewsey are decided by Luton Borough Council. A Lawful Development Certificate gives written confirmation if you're unsure.

How much does a house extension cost in Lewsey?

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.

How long does it take to get an extension approved and built?

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.

Do your builders in Lewsey handle all the trades?

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 Lewsey, we cover nearby areas such as builders in Houghton Regis, builders in Dunstable, builders in Leagrave and builders in Caddington. See every place on our areas we cover page.
