Fully Fitted Kitchen & Appliances/Removal of Exterior wall - Install Steel/Plaster wall - Ceilings/New floor/Electrics Ian is a professional and has in-depth knowledge of all building aspects which makes it easy to discuss the project end to end including estimates and time lines which are always of the utmost interest to the me. I agreed the price after several other quotes and Ian got to work…. during the build phase we changed our mind a couple of times with ideas that presented themselves and Ian was always accommodating and offered his experience in doing things a certain way in collaboration with our good ideas we had!! Ian started when he said he would and continued with reliable forecasts even when the plans changed. After many months not a single snag has been raised but I know Ian would be back to investigate if it did, Pleasure to leave a positive review and if you would like photo’s of the works, just drop me a message.

Kitchen Fitting- 28 May 2026
Extremely poor finish. I asked for new kitchen to be fitted to a rented property and paid for plastering and tiling the backsplash. Tiles were not installed to a good standard as can be seen and plastering not done to cover holes from previously ripped out kitchen. Also we were told it would be a 5 day job and we had to chase for over 7 weeks to complete. Tenant has sent images and complained so all in all not happy at all about finish as it was done to a poor standard

Extensions- 13 Jul 2024
Late review. Ste and the fellas built a wrap-around single storey extension for us in 2021. I can't recommend him highly enough. It wasn't the easiest build due to poor drawings we had from the architect, but Ste went above and beyond to make sure we had the extension that we wanted. Ste and the lads were positive, friendly and always had solutions to any challenges that came up. They also stuck to the original quote as much as possible, despite rising costs of materials at the time (2021). My wife and I worked from home for the entire build (about 4 months start to end), which wasn't ideal, but Ste and lads helped to make it work for us. 3 years on and we're well and truly settled and loving the extension. We're not sure that we'd ever want to go through a similar build again (at least not while living and working from home full time), but if we did then we would want Ste to do the job. 5 stars.
