No delay to the new city quarter in Winterthur despite official requirements

Cham ZG/Winterthur, May 2025

The city of Winterthur has granted planning permission for the Rocket high-rise and the three neighbouring residential buildings known as Tigerli. Despite the "sometimes significant conditions", developer Cham Swiss Properties does not expect any significant delays to the project.

Cham Swiss Properties AG assumes that there will be “no significant delay” to the Rocket & Tigerli construction project in the centre of Winterthur’s new Lokstadt residential district. As the property developer explains in a press release, the “sometimes significant conditions” imposed by the city of Winterthur as part of the building permit process have led to an in-depth review of the plans. However, the property company is taking the official conditions as an opportunity to “improve the project once again”. After all, Rocket & Tigerli should “fully fulfil its urban significance” with the adjustments.

This project consists of the 100 metre high Rocket tower and the three adjacent base buildings called Tigerli. This ensemble will be built in the centre of the new Lokstadt residential district in Winterthur. According to the information provided, the conditions now imposed by the city for this project primarily relate to the extent of public use of the top floor and access to the areas on the ground floor.

CEO Thomas Aebischer describes the formal legal appeal against the building permit as “a formality that comes with the process. For us, however, the focus is clearly on constructive dialogue with the Office for Urban Development and the Office for Building Permits.” This will also clarify whether a new building application is necessary.

Cham Swiss Properties AG was only created in April 2025 from the merger of Ina Invest AG and Cham Group AG.
