Planning Requirements

Once you have decided what the size and layout you would like to create, you will need to consider if planning is required. There are many factors that influence planning permission, but the good news is that some extensions are classed as Permitted Development, this means that some extensions won’t require permission. Loft Conversions are also an area which may be covered under permitted development depending on a number of factors.

To determine if your project requires planning, you can chat to us for advise or visit the Wiltshire Councils planning portals' interactive guide

Getting Planning Permission

If you don't need planning, chat to us to discuss your ideas and we can come out to provide a no-obligation quote. If planning is required, the next step would be to contact a registered architect who will come out to you to measure up and to understand what you would like to get out of your dream home. We always recommend checking the official Architects Register

Building Regulations

Your local architect should provide building regulation specifications within the drawings. If you would like to determine if your building work would require planning, check out the interactive guide for building regulations.

Quotes for your Home Extension

When getting quotes for your building project, building firms should always request a copy of your drawings, including structural drawings, and come to do a detailed site visit to ensure the quote offered is accurate and should not change due to any oversights. They should discuss with you how much of the build you are expecting a quote for and which finishes you would like to include in the quote. Quotes should be easy to understand with a clear payment structure.  

How We Work

Here at Wiltshire Builders we offer payment plans suited for your project. With ongoing projects such as new builds and extensions taking several weeks/months to complete, we offer weekly instalments to create a pay as you go style payment plan.

You can view our public liability insurance here as peace of mind your property is in safe hands. 


We are always mindful that our workspace is your home, during the build, we strive to keep mess, noise and dust to a minimum. We will respect your privacy and personal space, and wherever possible, we will work at times convenient to you. At the end of each working day, you can be assured the area will be left clean and tidy and that all tools and materials are stored safely and securely.


We use high-quality materials throughout the project and work to complement the existing structure, finishing in stone, brick or render to suit your taste. We take the time to review our work, making sure the finish meets our own high standards.


Once you are completely happy with the extension, we’ll leave you to enjoy your new living space, however we will always be here should you need anything else after the work is complete.
