Questão jurídica principal
Whether the communal rules on contiguity prohibit attached buildings only when separated by a property line, or also on the same parcel.
Decisão extraída
The cantonal court could reasonably interpret the regulations as allowing attached buildings not only across a property line but also on the same parcel; no arbitrariness was shown.
Fundamentação extraída
The text of Art. 8 and 9 ties contiguity to implantation on a property boundary. The project had no boundary-based contiguity, and the municipal practice did not compel a different reading.
