Kernrechtsfrage
Whether the north terrace wall had to be treated as a retaining wall limited to 1 m under Art. 21 of the Horw zoning plan.
Extrahierter Entscheid
The wall had no retaining function; Art. 21 applied only to retaining walls and did not prohibit the wall as planned.
Extrahierte Begründung
The plans showed level terrain between two retaining walls; the disputed wall stood on flat ground and merely served as part of the façade/screening element. The appellant's broader reading of Art. 21 was unsupported and would unreasonably extend the rule to all walls in sloping terrain.
