42 Upgraded Flats in Zurich

The Dangelweg 1/3 project involved converting and adding a new storey to a residential building in Zurich, resulting in 42 upgraded flats. The scope of work included replacing the entire facade and carrying out a complete interior fit-out of all flats, including the renovation of rooms, bathrooms, kitchens, and vertical service runs. Additionally, all windows were replaced to enhance the building’s efficiency and aesthetic appeal.

Prefabricated Roof Speeds Up Construction

To facilitate the new storey, the existing flat roof was removed and replaced using prefabricated timber elements. This method expedited the construction process, meeting the project's need for a short implementation period. Despite the sophisticated architecture involved, the project was successfully completed while adhering to a tight schedule.

Achieved Swiss Minergie Label

Sustainability was a key focus, as the property received the Swiss Minergie energy label, indicating high energy efficiency and improved living quality for the tenants. The project addressed the removal of contaminants, contributing to a healthier living environment.

Key Partner Collaborations

Contractually, the project was managed and implemented by several key partners, including Credit Suisse AG representing the building owner Interswiss “ZG” Immobilien AG, and Dachtler Partner AG Architects. Implenia Switzerland Ltd. took charge of modernization, development, and wood construction. Energy planning was carried out by Gutknecht Elektroplanung AG, while structural engineering and building physics were managed by Federer-& Partner Bauingenieure AG and Braune Roth AG, respectively.

Project Completed: December 2014 - June 2017

The construction began in December 2014 and was completed successfully by June 2017. The total construction volume, valued at 9.2 million CHF (~9.6 million USD), underscores the extensive work and coordination involved in this ambitious project.
