We are currently in the process of buying a new build and there were stark differences between what we saw of different home builders.
The house we have gone with is lovely, the same price and sq footage as other older houses on the market but with a layout that works for us without needing any renovation.
I think the feel can also depend on where on the estate you are, a couple of streets on our estate have brick road and no pavement, that would have been a no for me as those feel quite cramped but our street has a normal road and large pavement so feels nice and spacious and we will get onto our street easily from a main road so no going through a maze!
On a similar note the builder we went with builds houses that have shape to the outside rather than being a box, and has two parking spaces + for most houses. Some estates we viewed were sooo depressing, just cramped with boxy cookie cutter houses and cars on top of eachother everywhere, I would never consider a new build like that. It's worth noting ours was priced the same as other new builds like this.
I'd also recommend joining the Facebook group of residents already living there, we did and snagging is sorted very quickly on our site but sites seem to vary tremendously on this!
After inhering a nightmare of an established garden I did not have the will, skill or time to maintain in my current house I am excited to have a green square but everyone feels differently about that!
Basically I feel like new builds are similar to older houses in the sense they are not all the same, just do your research and find one that works for you.
