I have written here before, that we did loads of research for some years before doing our build - it was our hobby.
We were advised one small thing that I will share. We waited until we got planning permission through properly (only one, unreasonable objection that was soon sorted). Then, knowing there would be disruption along the street, we went round to all the houses that might be affected with a note and 2 bottles of wine ( I asked the nearest neighbour if there were any who might prefer cake).
It wouldn't have stopped a major complaint, but it did get everyone on-side and prepared to put up with minor issues.
Only a couple of weeks ago, when the pub opened and we were all outside enjoying a drink, one neighbour said 'when we got that wine we knew you were going to be good neighbours!'
And of course, each to their own, my sister lives in a 'hobbit house', but I love my new, warm, easy to clean, comfy house.
