Questione giuridica chiave
Whether the small annex of house no. 2 could intrude into the boundary setback
Decisione estratta
A small annex may extend into the setback if it does not impair the setback's public or private purpose.
Motivazione estratta
The purpose of the setback is not affected; the annex is subordinate and the statutory and analogical reading of the building rules allows limited intrusion by minor projecting parts.
