Questione giuridica chiave
To what extent may immission-mitigating measures be required from the builder under § 146 BauG and § 61 KBR?
Decisione estratta
The builder need not do everything technically possible; it is sufficient to take what is technically possible and reasonably exigible.
Motivazione estratta
The rules require buildings to be designed, altered, and maintained so that they create as little immissions as possible, but only within the limits of what can reasonably be demanded of the owner.
