How big can you build an extension without planning? The permitted development rules have recently been relaxed, allowing you to build an extension without planning permission of up to six metres or eight metres if your house is detached.


Whatever you choose TJW Projects realise that this is a major decision and you will want the best advice and workmanship possible. Our team are on hand to help you every step of the way to deliver your dream extension.

And if you do decide to extend, it could be very profitable. According to the Nationwide Building Society an extension to an average three-bedroom house creating a double bedroom and en-suite can add up to 23% to the value of your property – and this is just one example. So, let TJW advise you.
