The rules surrounding whether or not your home extension requires permission can be quite complex. This is the reason why here at Sovereign Home Improvements we are happy to deal with this side of matters for you. In the main though, planning permission isn’t required provided you meet certain requirements. These include your extension not being more than 50% of the size of your house and the roof and eaves being lower in height than those of your existing property. The extension must be built on the rear or side of your property (not the front). Also, the materials used to build your extension should be similar to those of your house so that it doesn’t ‘stand out’ too much.
