Summer residences close to Copenhagen in Denmark. The hedges are angled, from 180cm to 80 cm, securing privacy and optimal light access for plants close to the tip of the “slices”.
All homes have access to electricity, water, sewage and water. The houses must be less than 50 square meters, and you can only live there between April 1st to October 1st. Outside this period you can only stay there on weekends.

I dont know the particulars of the thoughts behind this, but originally they were made for people who live in apartments to be able to enjoy a country house for an affordable price. So these are meant to be casual areas with little or no traffic designed for relaxation. To me it seems pretty sufficient to have so few roads to so many houses though.
