If you're considering a DIY project for a house extension, loft conversion, or garage conversion in Cambridge, it's essential to understand several key factors. Planning permission is a critical first step; you may need to apply to your local council, especially for significant changes. The average cost for planning application fees is around £206.

For the build itself, materials and structural elements can range significantly. For instance, a basic loft conversion might cost around £20,000, while a more complex house extension could be upwards of £30,000. Ensure you source quality materials from local suppliers to keep costs manageable.

It's also crucial to comply with building regulations to guarantee safety and quality. If you're not a certified professional, consider hiring a surveyor or consultant to ensure compliance, which might add about £500–£1,500 to your budget. Certifications like NICEIC or Gas Safe may be needed if your project involves electrical or gas work. Lastly, don’t forget to factor in the time commitment, as DIY projects can often take longer than expected.
