What You Need to Know About House Extensions
Do I need planning permission for a house extension?
It varies quite a bit depending on the size, the spec and how complex the build is. As a rough guide, a single storey extension in the UK typically starts from around £1,500 to £2,000 per square metre, though this can go up for more complex builds or higher end finishes.

Will a house extension add value to my home?
In most cases, yes, and often by quite a bit. Adding good quality living space is one of the most reliable ways to increase what your home is worth. How much value it adds depends on the type of extension, the size and what the local market is doing, but in Warrington and Cheshire, demand for larger family homes is consistently strong.

What is the 50% rule for a house extension?
The 50% rule is a permitted development restriction that limits how much of the land around your home can be covered by extensions and outbuildings combined. The total can't exceed 50% of the area of land that surrounded the original house. It's one of a number of criteria that determines whether your extension qualifies for permitted development or needs full planning permission.
What's the difference between a single and double storey extension?
A single storey extension adds space on the ground floor and are most commonly used to extend a kitchen, living room or dining area. A double storey extension adds space on both floors, which makes it a great option if you need an extra bedroom as well as more downstairs living space. Double storey extensions tend to offer better value per square metre, but in most cases they'll need full planning permission.
