A well-designed house extension is one of the most cost-effective ways to add both living space and significant value to your home. Brick Builds has completed hundreds of extensions across Devon, and our team brings the same care and craftsmanship to every project, large or small — whether it is an open-plan kitchen extension, a two-storey rear addition, or a side-return utility room in Sidmouth.

We handle all aspects of the build, including planning applications, structural calculations, groundworks, brickwork, roofing, windows and internal fit-out. Our clients in Sidmouth and across Devon consistently tell us that our communication sets us apart — you will always know exactly what is happening on site, and our fixed-price quotes mean no nasty surprises when the project is complete.

House extensions in Devon need to complement the existing property and satisfy local planning guidelines. Our 17 years of experience working with Devon planning authorities means we know exactly what will and will not gain approval for your Sidmouth property. We match brickwork, stone, render and rooflines precisely, so the extension looks like it was always part of the original building.

Planning & Building Regulations for Extensions in Sidmouth

Many single-storey rear extensions in Sidmouth fall under permitted development, but larger, two-storey or side extensions usually need a householder planning application to East Devon District Council. We check which route applies to your home, prepare the drawings, and handle Building Regulations sign-off so your extension is fully compliant when you come to sell.

Frequently Asked Questions – House Extensions in Sidmouth

Do I need planning permission for a house extension in Sidmouth?
Many single-storey rear extensions in Sidmouth qualify as Permitted Development and do not need full planning permission. However, rules vary depending on your property, whether it is listed, and whether it is in a conservation area — which is common in Devon. We advise on this for free as part of our initial consultation.

A standard single-storey extension in Sidmouth takes approximately 10–16 weeks from groundworks to completion. A double-storey extension typically takes 16–24 weeks. We provide a detailed programme of works before starting so you always know what to expect.
How much does a house extension cost in Sidmouth?
A single-storey extension in Sidmouth typically costs £30,000–£60,000 depending on size, specification and finishes. Double-storey extensions range from £60,000–£120,000. We provide fully itemised, fixed-price quotations — call 01460 353121 for a free visit.
Can you match the existing brickwork or stonework on my Devon property?
Yes — matching existing materials is something we take great pride in. We source appropriate facing bricks, local stone and render finishes from our established network of Devon suppliers to ensure the extension is visually seamless with the original structure.
