It depends if you want to live in a shoe box, with a window box for a garden, with 25% housing association neighbours, with cars parked all over the place and blocking the narrow roads, directly looking over/overlooked by the neighbours, crammed in like battery hens, with endless defects which the NHBC won't be bothered about, with paint peeling off the external timber but you can't get a ladder up as the neighbours house is too close, with tiles blowing off in a summer breeze, in a bland featureless monotonous environment leading to an addition to prozac
Or not
Plus you get more for the same money if you self build and don't pay over the odds for land
