Key legal question
Whether the Baustopp was lawful under the planning and building rules.
Extracted holding
Yes. A Baustopp is justified when work plausibly deviates in a material way from the approved permit; the court found such deviations credible here.
Extracted reasoning
A summary comparison of the built structure and the approved plans showed material differences in roof shape, room layout/use, and apparent storey count; the access and carport also raised unresolved issues affecting the gestaltungsplan.
