Questione giuridica chiave
Whether the appellant had standing to challenge the building permit before the cantonal court and the Federal Supreme Court.
Decisione estratta
The appellant had standing because the project was close enough, visible from her attic, and could diminish her protected interest in view and building-related interests.
Motivazione estratta
Standing under Art. 89 LTF is not assessed more restrictively than cantonal standing rules. A neighboring owner need only show a direct, concrete, and sufficiently specific interest; distance is relevant but not decisive. Here the appellant's property was nearby and the projected addition could materially affect her view and use of the property.
