Groundwork & Foundations- 3 Aug 2026
BMR has turned my dream self-build into a nightmare. An independent structural engineer has confirmed that the foundations BMR constructed are not in accordance with the approved structural drawings and require remedial structural works before my house can even be built. Defects in BMR's work: 200mm lost from both the front and rear elevations of the approved footprint. Internal load-bearing foundations constructed in the wrong location. Foundation levels between 30mm and 75mm out across the build. Thousands of pounds in remedial engineering, bricklaying and construction costs, plus weeks of delays. The setting-out engineer was appointed and paid by BMR as part of the contract I paid for, yet Baden tried to shift responsibility instead of taking ownership. I gave Baden every opportunity to inspect the site with my contractor and discuss a solution. Instead, he denied liability, refused to discuss the issues any further, and simply walked away from the problem.

Daniel quoted comprehensively and clearly for both jobs that I needed, building an extension and a raised patio at the end of the garden. He worked extremely hard and diligently every day. Also he would summarise what he would do next and we discussed any changes etc and which tiles or render I preferred. I am very happy with both the patio and extension and Daniel finished everything off to an excellent standard and went above and beyond the quote. I would not hesitate to use him again and recommend him highly.
