• SINGLE STOREY EXTENSIONS DRAWINGS •
Single Storey Extensions are a great way of adding extra reception rooms or a wow factor larger kitchen / dining area. We will prepare all the relevant drawings required to obtain Planning Permission and Building Regulations approval for your project. Both approval certificates last 3 years, giving you ample time to obtain the recommended minimum of 3 quotes from local builders. They can also build from our drawings.
WILL I NEED PLANNING PERMISSION?
Not necessarily! Many rear or side single storey extensions can be added under permitted devlopment as long as:
- The extension doesn't project more than 4m for attached houses and 8m for detached
- Side extension is less than half the width of the house
- The eaves height is under 3m if within 2m of a boundary
- The ridge height is under 4m
- The extension is less than 50% of your land curtailage
- The extension isn't a wrap-around extension
- You don't live in a designated area
- Permitted development rights haven't been removed
WHAT WILL IT COST?
For Construction costs this is a difficult question to answer accurately as the price will depend upon many factors, including size, features, quality of finish, and even the builder used. Builders will only be able to give accurate quotes once they have the approved Building Regs drawings. However, as a rough estimate it is common to assume an average single storey extension will cost in the region of £1600.00 per square metre.
