What it is about
A new development is being built on the Zugerland Verkehrsbetriebe (ZVB) site between Chamerstrasse and Gotthardstrasse, covering an area of around 3.4 hectares: an underground bus depot, a new building for the emergency services and the cantonal administration, and flats and offices on the northern part of the site.
In March 2024, the electorate approved the ‘An der Aa II’ development plan by 81.3 per cent. The Zug Pension Fund has acquired the building rights for the ‘Baufeld Nord’ site. At least 160 flats are planned there, with 40 per cent of the living space being affordable housing.
What changes for the neighbourhood
The area, which is currently closed off, is to be opened up: a new footpath will bridge the gap between Stierenmarkt and the railway station; the path along the Schleifedamm will become a footpath and cycle path; the Siehbach stream will be opened up; and the roofs will be greened. In addition, a neighbourhood square will be created.
During the construction period, buses and the emergency services will be based in temporary facilities on the gasworks site. Once the ZVB has moved into its new base, the gasworks site will be handed over to the city. The city can then use it for public purposes or to provide affordable housing.
