Moved onto a new build redrow flat 12 years ago. Tremendous, solid construction. So much so that the surveyor who came round to value it when we were selling told us that he'd been waiting for ages for one of them to come on the market.
Apparently he knew the development manager when the houses and flats were being designed and going up. The manager from redrow always said he wanted them to be absolutely solid, and they were. We didn't have any settlement issues in the 8 years we were there.
I'd buy from redrow again but I don't think they exist anymore.
Have to agree with the quality of the build. They are definitely going, well their website has a number of developments around the UK going up. We had several constructors on site but it was the Redrow houses that had the most interest and people trying to get their names down for a plot. Apparently there were 17 others wanting our house if we had dropped out (was never happening)
