Rear, side, front house extensions and more by expert architectural designers around Swindon.
Designing a House Extension in Swindon
Our process is made up of 5 optional steps, to provide a stress-free, personalised service. We will typically start by meeting you in person and surveying your property to get an understanding of your goals and the opportunities your house presents.
Following this, we will draw our concept designs ready for the next stage; planning and building regulations. Many residential extensions in Swindon do not call for planning permission; but whatever permissions are needed, we will be with you to help gain them, liaising with local authorities and relevant bodies on your behalf.
Finally, the build itself! We produce in-depth drawings for your builders to instruct the creation of your extension, as well as overseeing the whole process, vetting workers and regularly assessing the site. Our build management makes sure there are no unexpected events or shortcuts being taken, allowing you to have peace of mind throughout the process.

Planning Permission & Permitted Development for Extensions in Swindon
Once your design is finalised, the next step is the planning process.
In many cases, your extension may fall under Permitted Development Rights, meaning planning permission isn’t required, but this depends on the size, scale and location of your project.
We always recommend checking with Swindon Borough Council to confirm whether your project requires planning permission. Our team can help prepare and submit all necessary drawings and documents to ensure your application is valid and has the best possible chance of approval.
Whatever planning route your project takes, CK Architectural Swindon can handle it for you, advising, preparing, and even liaising directly with the local planning authority on your behalf.
Building Regulations for House Extensions in Swindon
Before your extension build can begin, you’ll need a building certificate from building control, either through Swindon Borough Council or an approved private inspector. This requires:
Building control approval
Fully approved plans
Building regulation drawings
A site inspection
We can handle all of these steps for you, making sure your project complies fully with building regulations and leaving no room for error. Once approved, our detailed drawings can be handed directly to builders for quoting and construction.
Building a single storey extension
Once planning and building regulations are complete, it’s time to start the build.
You’ll need to choose a trusted builder, either through our recommendations or your own contacts, agree on a quotation, timescales and services, and sign a contract.
CK Architectural Swindon also offers project management services, so we can oversee the build on your behalf. This ensures everything runs smoothly, stays on budget, and delivers the high-quality finish your home deserves, without unnecessary stress or expense.
