I contracted this company to modify containers for a house build. My experience with them was awful. They got pretty much everything wrong at least once; basic stuff like not checking the supplied window specs so getting glazing orders wrong, then putting windows in the wrong place, plus supplying incorrect measurements of the containers so they didn't fit my foundations, and taking 7 months to complete the build instead of the promised 6 to 8 weeks. Then they breached their own contract and the company directors knew they were in breach and just didn't care. I found them to be incompetent and unethical and am still trying to get some costs back via Fair Trading, who they admitted they deal with a lot.
