Our House Extension Services

We design and build extensions that enhance your home’s functionality, value, and appeal. At Nelhams & Sons Ltd we specialise in:

Single & Double-Storey Extensions

Rear kitchen and dining extensions to create open-plan family spaces, side-return extensions for Victorian and Edwardian terraces common across Staines and Hampton, and double-storey additions for extra bedrooms and bathrooms. We handle planning permission with Spelthorne Borough Council and all Building Regulations compliance.

Wrap-Around & L-Shaped Extensions

Comprehensive wrap-around extensions for corner plots and larger properties across Weybridge, Walton-on-Thames, and Esher. We combine rear and side extensions into a single project to maximise the space and light your family needs, with careful attention to matching existing materials and brickwork.

Frequently Asked Questions About House Extensions in Surrey

Do I need planning permission for my extension in Staines or Surrey?

Many extensions across Staines and Surrey can be built under Permitted Development rights without needing a planning application, including single-storey rear extensions up to 6 metres for terraced and semi-detached homes or 8 metres for detached properties. However, rules vary depending on your property type, whether you are in a conservation area, and any previous extensions that have been built. We assess your specific situation and liaise with Spelthorne Borough Council or the relevant Surrey authority on your behalf.

What types of house extensions do you build?

We build single-storey rear extensions for kitchen and dining spaces, double-storey extensions adding bedrooms and bathrooms, side-return extensions for the Victorian and Edwardian terraces common across Hampton and Staines, wrap-around L-shaped extensions, and garden rooms or orangeries. Every extension is designed to complement your existing property whilst maximising space and natural light.

How long does a house extension take to complete?

Single-storey extensions typically take 8-12 weeks to complete, whilst double-storey extensions require 12-16 weeks. These timelines include Building Control inspections at key stages and allow for weather contingencies. We provide a detailed construction schedule during the quotation process and keep you updated throughout the build.

Can I stay in my home during the extension work?

Yes – the vast majority of our clients in Staines, Shepperton, Walton, and across Surrey remain at home throughout the build. We plan construction phases carefully to maintain access to essential facilities, and for kitchen extensions we arrange temporary cooking facilities. We run clean, tidy sites and communicate daily progress so your family can plan around the work.

Will my extension match my existing house?

Absolutely. We take great care to match brickwork, roof tiles, window styles, and architectural details to your existing property. With 48 years of experience working on the varied housing stock across Surrey – from Victorian terraces to 1960s semis to modern detached homes – we know how to source the right materials and apply the right methods to achieve a seamless result.

How much value will an extension add to my property in Surrey?

In Surrey’s property market, a well-designed extension typically adds significant value – often exceeding the build cost. Single-storey kitchen extensions can add 10-15% to your property’s value, whilst double-storey extensions adding a bedroom can increase value by 15-20%. The exact uplift depends on your specific location, property type, and the quality of design and finish. We build extensions with both your family’s enjoyment and your property’s long-term value in mind.
