Types of Home Extension We Build in Yeovil
Single-Storey Rear Extensions
The most popular way to create a bigger kitchen-diner or family living space. A single-storey rear extension is often achievable under permitted development, keeping cost and timescale down.
Double-Storey (Two-Storey) Extensions
Need an extra bedroom and bathroom as well as more space downstairs? A two-storey extension usually offers the best value per square metre and can transform how your whole home works.
Side Return & Wrap-Around Extensions
Common on Yeovil’s semi-detached and terraced streets, a side-return or wrap-around extension makes use of an underused side passage to open up the ground floor.
Kitchen Extensions
Extending to create an open-plan kitchen is one of the highest-value home improvements you can make. Once the structural work is complete, our team can also design and fit your new kitchen, finished to the same standard as the build.
Not Ready to Extend? Consider a Garden Room
If planning constraints or budget make a full extension difficult right now, a bespoke garden room or a loft conversion can be a cost-effective alternative way to add usable space to your Yeovil home.
Our Extension Process
- Free consultation — we visit your Yeovil property, discuss your goals and budget, and talk through what’s achievable.
- Design — our designer produces plans that suit your home’s style and meet your practical needs, considering light, layout, insulation and energy efficiency.
- Planning & Building Regulations — we advise whether your project needs planning permission or falls under permitted development, and handle Building Regulations applications on your behalf.
- Build — our team manages groundworks, structural work, roofing, windows and doors, plastering and utilities, keeping you updated throughout.
- Completion & sign-off — you receive Building Control completion certificates, essential paperwork for any future sale of your home.
Planning Permission for Extensions in Yeovil
Yeovil falls under Somerset Council for planning purposes. Many single-storey rear extensions fall within permitted development rights, but this depends on your property’s history, its size, and whether it sits within a conservation area — parts of central Yeovil do. We check this for you before any design work begins, so there are no surprises later.
You can review the current rules yourself via Somerset Council’s planning permission guidance or the national Planning Portal, though we’d always recommend letting us run the checks as part of your free consultation.

Frequently Asked Questions
Do I need planning permission for a home extension in Yeovil?
Not always. Many single-storey rear extensions are covered by permitted development rights, provided they stay within set size limits and your home isn’t in a conservation area or subject to an Article 4 direction. We assess this for every project during your free quote.
How much does a home extension cost in Yeovil?
Cost depends on the size, design and finish you choose, along with groundworks and any structural requirements. We provide a detailed, itemised quote after our initial site visit so you know exactly what’s included before any work begins.
How long does a home extension take to build?
A single-storey extension typically takes several weeks to a few months from start on site to completion, while double-storey extensions take longer. We’ll give you a realistic build programme as part of your quote.
Do you handle Building Regulations for extensions?
Yes. We manage Building Regulations approval as part of the build and provide you with all completion certificates once the project is signed off — documents you’ll need if you sell your home in future.
