Conversions - General- 14 Mar 2026
We hired Jason and his team to help convert our separate kitchen and dining room into one open plan kitchen/diner space and also renovate our bathroom. The team arrived on time each day and were very communicative on progress and any queries. They worked to a design I'd provided and helped us navigate some issues with moving the soil stack and building the piers for the steel beam. They worked to the design and we're really pleased with how the space works.

Extensions- 5 Feb 2019
I hired Chris and his team to do a complete refurb of my 3 bedroom house. I had a complete rewire of the property, plaster throughout walls and ceiling, new doors throughout, new floors, new pipework for downstairs which needed replacing, internal wall removed, new kitchen, windows and patio doors, utility room with downstairs toilet added and decorating throughout. It was a massive job and I am absolutely thrilled with my new house! Chris helped me choose suitable options to stick within my budget which was very helpful. He kept me updated every week with a financial spreadsheet to show what had been done and exactly where the costs had been allocated. The whole job took around 8 weeks and I was kept updated the whole way through the process. Quality of work was of a high standard and Chris, Bill and team were super friendly and happy to answer all my questions. I would highly recommend them and use them again myself for any other projects that I might have.
