Question juridique clé
Whether a multi-family house is zonally permitted in the WE2 zone under St. Gallen law and Uznach's building regulations.
Solution extraite
Yes. The zoning scheme may validly differentiate within the residential zone and restrict construction to single- and two-family houses; the planned multi-family house is therefore non-conforming.
Motifs extraits
Art. 11(2) BauG/SG is not exhaustive; the term 'especially' allows further differentiation criteria. The communal rule limiting the zone to single- and two-family houses is a permissible differentiation of use within the residential zone, supported by legislative materials and not arbitrary.
