Public parking spaces can be good, but are they used? Who keeps them clean? For small plots, they might be rented out so that one less parking space needs to be created on the own property. I just fear that the streets are still blocked because otherwise you have to walk 1 meter more.
The playground is great, maybe also a multi-purpose court for teenagers.
I wouldn’t prescribe too much. Rather a framework plan with a points system. So that the 300 sqm lawn can be balanced with a robot mower and a bird-butterfly hedge as a enclosure. The missing cistern with less sealed surface.
Building heights are a tricky issue. A bungalow or a Flair 113 in the shadow of our 2 townhouses with 40° roof pitch and maybe 6 m distance can only dream of sun. If the development area is large enough or on a slope, this might be avoidable by allocating the plots accordingly.
Filling heights must be fixed.
However, the municipality should consider not demanding anything it does not comply with itself. I can’t require retention systems, but the big sealed street just runs into the sewage system.
The gardens must be eco-friendly, the playground is dead without little trees and flowers.
