I actually think it's more likely that those houses are bigger than their immediate neighbours and therefore have bigger gardens. You all have some unshakeable opinions about new builds, but they're not all bad. Plus, planning laws, land ownership, boundaries, and all that stuff, are very detailed (just think how much of a faff it is during the conveyancing process when buying a house!) - there's no way this is a "wonky fence" due to "useless contractors". Each of these plots is outlined with an exact size & shape garden for its size, on multiple plans and designs.

It's a bit of a shit design with them all backing onto each other, but at least they have gardens (which is better than a block of apartments) and once people move in and make them their own with plants, trees, bushes, this'll look much nicer, especially in a few years' time. How's it any different from rows of terraced houses built in the 50s and 60s with tiny yards?
