Key legal question
Whether the proposed new roof superstructure on the north side complied with zoning and integration requirements.
Extracted holding
The roof addition did not fit the required relationship to the roof body and could be refused, although the deficiency could be remedied in a revised project.
Extracted reasoning
The cantonal court could, without arbitrariness, find the unusual fenestrationless structure incompatible with the integration duty and the zoning rule requiring an appropriate proportion to the roof body.
