Single and two storey extensions are the most common type of home improvement to provide additional space or an additional room/rooms.

Often extending your property can be more cost effective than moving house. We have provided Building Control services on thousands of domestic extensions and are able to advise on the typical problems which you may encounter prior to commencing your project.

  • Thank you to my Inspector Mark Povey for his help and support during what turned out to be a very stressful build project. Your company gave a great service from start to finish and Mark was always available when asked for, arrived promptly, on time and was very professional and helpful. It’s a shame the same couldn’t be said for the cowboy builders who carried out the project!

    Miss Tracey Handley, Ludlow (November 2018)

So much so myself and my builder both recommended approved inspectors to my brother in law who has just started his own extension.
