Letchworth Garden City was the world's first garden city, founded in 1903 and laid out with tree-lined streets and Arts and Crafts cottages. Homes in Letchworth Garden City include Arts and Crafts cottages, interwar houses and post-war estates.
Most homes in Letchworth Garden City fall under the Letchworth Garden City Heritage Foundation's Scheme of Management, so many external changes, from extensions to new windows, need the Foundation's consent as well as any planning permission. Post-war houses here often have good-sized gardens and straightforward layouts, which suit single-storey rear extensions and open-plan kitchen-diners. 1930s semi-detached houses are classic candidates for hip-to-gable loft conversions and wraparound rear extensions.

Not always. Many single-storey rear extensions, loft conversions and garage conversions in Letchworth Garden City can go ahead under permitted development, but the limits are strict and some homes have lost those rights.
Planning applications in Letchworth Garden City are decided by North Hertfordshire Council. Parts of Letchworth Garden City are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. In Letchworth Garden City, the Heritage Foundation's Scheme of Management adds its own consent for many external changes, separate from planning permission.
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.

Choosing builders in Letchworth Garden City 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. Letchworth Garden City is about 18 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Hitchin and Stevenage.
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.
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.
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 Letchworth Garden City are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Applications in Letchworth Garden City are decided by North Hertfordshire 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 Letchworth Garden City, we cover nearby areas such as builders in Hitchin, builders in Stevenage, builders in St Paul's Walden and builders in Kings Walden. See every place on our areas we cover page.
