Restoration & Refurbishment- 17 Feb 2026
We recently had our bedroom ceiling vaulted by Joel and the team, and we couldn’t be happier with the experience. From start to finish the team were punctual, hardworking and genuinely pleasant to have in the house. They went out of their way to minimise disruption to our day-to-day life and left everything clean and tidy at the end of each day, which we really appreciated. The finished vaulted ceiling looks fantastic and has completely transformed the room. We were so impressed with the quality of their work and professionalism that we’ve since asked them back to replaster our landing and stairs and fit new carpets. We would definitely recommend them without hesitation.

Conversions - General- 10 May 2023
Andy, Alex and team just completed a full garage conversion for us. We couldn't be happier with how things went. The finish is fantastic and so was the communication and professionalism from day 1. Rather than being an inconvenience having building work going on, it was actually a pleasure to have them around! At some point we will be looking to do an extension, so very glad we have found someone we can trust 100% to do the work! Highly recommended.

The fitting of a personal door into the garage for easy access from the house. Excellent workmanship. What a joy to have people working on your property that really know what they are doing. They tidied up afterwards also to a high standard. The personal door into the garage looks as if it was there from the start of the build. Very professionally completed would certainly recommend LJM Carpentry.

Bathroom Fitting- 18 Apr 2026
Connor converted our downstairs loo into a shower room. He was very knowledgeable and wasn't fazed by the unexpected (a stud wall that wasn't a stud wall!!). He gave great advice from the quote through to the finished room, advising on ordering through to which door would give us optimum space. His price was very competitive and he provided lots of extras eg. replaced an outside tap and shaved down a sticking door. Connor has a great eye for detail and worked hard to provide us with a lovely shower room!

Jim was good until asked to correct a problem. Then his promise of coming back to correct anything that went wrong turned into ignoring numerous messages and failing to keep his promise. Not what you expect on a 10k plus job.

Shaun and his team did a very good job converting our garage to an office. Communication was very good throughout, nothing was too much trouble and the quality of the work was exemplary. The job came in at the cost given in the quote. Shaun and his small team were friendly, chatty and informative and helpful. I would definitely use them again for any future building work.

Very pleased with the extension carried out. Fair pricing on the quotation, especially in todays climate. Great guys who made the whole process, which seemed daunting at first, actually become very fuss free. We love our new space and cant thank them enough for all their hard work and the wonderful addition to our house. I would recommend Vision Build to everyone.

A rare find! What luck finding Rob on this website to remove our wall and make good. My husband was drawn to him because he was the only builder who took his time to measure up and check everything before his quote. He is an absolute perfectionist and his attention to detail is fantastic. He was great at project managing and was able to take me step by step what he needed to do to get the work done, each day I knew what was happening. Day 1. Steel prep work and measuring up. Day 2. Props went in and wall removal began. Day 3. Wall is gone and electrical work sorted. Day 4. “Packing in” is done. Day 5. Wall is filled in ready for plaster board. He also removes an old porch door frame and makes good. So neat no plastering needed. Day 6. Plaster boards are in and walls ready for plastering, props come down and packing finished. Day 7. Floor is levelled to living room. Day 8/9. Plastering is done including my kitchen ceilings. Day 10 skirting is added and flooring laid. Great builder, great service, very lovely assistant builder ;) will be calling him back to do some other work.
