There have been numerous posts asking for references on particular builders [which is a good way to find out about other peoples experiences] but volume builders may employ several different contractors to construct their homes & as with any industry there are the good, bad & the ugly.
One persons accolades of a firm may not necessarily give a correct picture of what you may end up with. It will possibly come down to the expertise of the supervisor for your particular home & what contractors are engaged to do the actual job.
If I were for example looking at the finish in a display home I would be asking if the same trades were going to be doing the work on my new home.
At minimum I would be requiring [contractural wise] that the display home standard was what I was receiving for my home.
Naturally, building firms engage their best contractors to build their display homes, but they may not be the contractors on your home.
