Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

Restoration & Refurbishment- 21 Jul 2025
Despite the fact that CRI was a new member on the app with very few reviews, Jon came across very professional and accommodating and priced the job swiftly and fairly. I took a pun and awarded CRI the job. It took circa 2weeks and during this time Jon and the team where exceptional. In order to catch up and meet deadlines they were more than happy to do full weekends and always left the site clean and tidy. During the works, the team always kept me in the loop with photo updates on whatapp and next steps. I would highly recommend CRI.

Your Highbury extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Highbury?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Highbury extension builder’s ability to deliver a result that meets your expectations.
