Sophisticated home extension design Somerset

Adding an extension to your home should be an exciting journey of transformation, but is often quite the opposite if you don’t know where to start, or if you have employed a build and design company lacking in vital communication and customer service skills.

Your home is your castle, so we completely understand you want to be kept informed throughout the design and installation process – which is why we are with you every step of the way.

What size extension can I build without planning permission?

Planning permissions were relaxed in 2019 across England, so, as long as your home isn’t a listed building or located in a conservation or Article 4 area, you can add a home extension up to 6 metres without planning permission or up to 8 metres for detached homes.

Bearing in mind there are over 80 conservation areas in South Somerset alone, dealing with planning permission is an issue no one wants to deal with – apart from us, of course! If your project requires it, our team of experts will take care of the entire process for you.
