New standard at JVA Bostadel

The Bostadel prison in Menzingen is about to be renovated and extended. This project is not only necessary in order to fulfil the structural and operational requirements, but is also intended to improve the quality of the prison conditions for older prisoners and those in long-term custody.
The Bostadel prison, built between 1972 and 1977, is showing clear signs of wear and tear after decades. Structural modifications to increase earthquake safety, fire protection and energy efficiency are urgently needed to ensure the safety of inmates and staff. The comprehensive renovation project includes both the modernisation of the building technology and the construction of a new special department, which will serve as a temporary facility during the construction phase.
Refurbishment during operation
A central aspect of this project is the refurbishment during ongoing operations. The new building provides a temporary alternative solution during the renovation and is particularly geared towards the needs of older and long-term prisoners. This approach was developed in close cooperation with the Prison Concordat of Northwest and Central Switzerland and the Federal Office of Justice to ensure the smooth operation of the prison.
Architectural innovation
The winning project by Eggenspieler Architekten AG and architecture aménagement s.a. impresses with its well thought-out planning and architectural innovation. The extension creates additional outdoor areas and ensures a pleasant environment by optimising the lighting of the interior spaces. The result is the realisation of a modern and sustainable prison infrastructure.
Efficient and sustainable project
According to a rough cost estimate, the total costs amount to CHF 66.6 million, or CHF 50.35 million net after deduction of federal contributions, making the project efficient and sustainable. The involvement of the cantonal governments of Zug and Basel-Stadt guarantees the fulfilment of modern standards and requirements.
Setting the course for the future
Following approval by the cantonal governments and the forthcoming procedure in the cantonal parliaments, the project will be realised in stages. The extension is scheduled for completion by 2028 and the full refurbishment by 2031, preparing Bostadel Prison for the requirements of the coming decades.
