Immediately after receiving the building permit at the end of January 2025, the EVZ specified the construction plans and began the first preparatory work for the expansion at the beginning of May 2025. The focus in the first year of construction will be on the south volume, where a single-storey extension will be built that will, among other things, provide more spacious access to the arena. The first floor will also house the new Sportsbar 67, the fan store and the skate counter for free skating. A terrace will be created on the roof of the extension, which will be freely accessible during opening hours. On the second floor, a new restaurant for match operations will replace the current 67 Sixtyseven Sportsbar.
In parallel to the construction work in the south, various preparatory work is starting on the inside. In particular, the roof structure will be reinforced in preparation for the planned raising of the rear roof area in summer 2026. Work on the relocation of Weststrasse by the City of Zug also began at the start of May. All work will be planned and carried out in such a way that match operations can begin normally in the 2025/26 season. The first work on the larger north volume will begin in November, although the building construction can only be completed once the roof has been raised. Due to the complex work involved in raising the roof in summer 2026, the first home matches in the 2026/27 season will not be possible until mid-October. All construction work will be completed in late fall 2027 so that the opening of the expanded stadium can still take place in the 60th anniversary year of the EVZ.
Free ice skating will always be possible in winter. Together with the artificial ice rink, the EVZ will create a mobile winter landscape as early as November 2025, which will offer an ice rink, ice paths and various recreational and catering facilities.
