> Quite. I dare say you're not likely to find a jack-the-lad jobbing builder from Germany whose going to come over and make you a shonky over-budget garage. There was, I imagine, a large degree of selection beyond nationality in the OPs choice...
We invited quotes and scheduling in from 6 building companies based on very detailed specs from the architect on construction and materials.
2 of the companies couldn't even be arsed to turn up to discuss the job when they said they would - this was a 6 figure budget job by the way.
Of the 4 that did, one of them never got round to sending a quote, and the other 3 only supplied 'ballpark' quotes and wouldn't commit to any timescales.
Our architect then mentioned a German company one of his clients had used, so we got in touch with them.
Within a week, they had sent someone over with a comprehensive resume including references and details of other work they had done for us to check out. 3 days later we received an extremely detailed quote - a copy of which was also sent to the architect - including a detailed time schedule, number (and names) of who would be working on it along with their resumes.
As I mentioned in my OP, they were highly impressive and did a fabulous job.
In all my years of using British builders on a variety of building projects, none of them have come close to the German company we have just used.
