No matter what your DIY skill level, it can be an attractive idea to undertake some of the manual labour for an extension to your home yourself. Not only does it offer the opportunity to reduce costs, but given the shortage in skilled labour in the construction industry at present, it might even help your build cross the finish line sooner. 

Realistically, if you're thinking about building an extension entirely from scratch yourself, you'll have a good idea as to whether you have the appropriate skills to do so already. However, it's never been easier to learn new construction skills from the internet, and it's certainly possible to learn the basics of a new technique in order to undertake it during your build.
