Is there any reliable new build

Hello I'd like to know if there are any off plans new build or recent build that havent cut corners? E.g. which company does decent new build? I'm thinking of buying a house and a new build could be nice for the proper insulation/double glazing/warmth.. but I also see a lot of cheap looking recent houses (and this is without even looking at them in depth) and that's clearly not what I want. I want something reliable and resalable. Thank you

Ps: I'm looking for houses near completion or recently completed as I want to be able to move in sooner rather than later. So cannot buy a land and contract my own building company.
