How to Build a Home Extension
Are you hesitating to move because you love your house and where it is, but you just need some extra square footage, then a house extension can transform the space into a stunning kitchen room or open plan living room?
Whether you intend to extend up, out or to the side, there are some key things to know before your project begins.
So What Should You Consider Before Building an Extension?
Any Shared Walls
If building your extension involves digging or building foundations within 3m of the boundary, party wall or party wall structure, or digging foundations within 6m of a boundary, the work will require you to comply with the Party Wall Act.
The next important point will be to respond to the question:
Do I Need Planning Permission When Building an Extension?
Not necessarily. In many cases you will be able to build an extension under Permitted Development (PD). These rights allow certain works to be carried out to your home providing you meet the criteria.
Under Permitted Development, the following rules apply:
You can extend a detached property by 8m to the rear if it’s a single-storey extension, or by 3m if it’s double
A single-storey extension can’t be higher than 4m on the ridge and the eaves, and ridge heights of any extension can’t be higher than the existing property
