The Sonnenberg complex is to be repositioned as a distinctive hotel complex with national and international appeal, specifically oriented to the place. The project design is convincing due to its embedding in the sensitive landscape and its sensitive engagement with the site. It also provides the economic basis for a successful implementation.
The Hotel Sonnenberg will remain as the core building and will be supplemented by new buildings at the rear. It will be returned to its original use as a hotel. The building of the former Hotel Kulm will also be preserved in its external appearance, except for a discreet intervention. Flats will be created here. There, flats for hotel use can be positioned in such a way that they are hardly noticeable from the outside. The new buildings consist on the one hand of two buildings with flats, which are positioned to the south of the hotel. On the other hand, in the north of the perimeter, new, moderately sized point buildings with flats are planned, which are oriented to the existing residential buildings in Seelisberg in terms of volume and design. The distinctive, publicly usable outdoor area will be retained.
The Government Council of the Canton of Uri has approved the partial revision of the land use plan and the Sonnenberg neighbourhood design plan - the planning instruments are therefore legally binding. The planning application is expected to be submitted in the 3nd quarter of 2026.
