Campus Unlimitrust SICPA

Located in the municipality of Prilly, a stone's throw from Malley station, the project is the first stage in the development of a plot of land bordered to the north by the SICPA headquarters and to the south by the Renens road.

Built on the initiative of SICPA, the world leader in security inks and authentication, identification and traceability systems, the Unlimitrust Campus is a place dedicated to innovation in the field of security-related technologies.

Faced with the growing challenges posed by digital complexity and threats to data security, the campus seeks to ‘advance the trust economy’ by encouraging dialogue between start-ups, businesses, investors, academics, institutions and other stakeholders in the field of trust technologies.

In 2011, SICPA launched an architectural competition for the extension of its headquarters and obtained a building permit in 2014. In 2018, RDR architects was commissioned to adapt, develop and carry out the first phase of this ambitious project. From 2021 onwards, the teams from CSD and Studios architecture in Paris will be involved in the development of the interior common areas. The exterior landscaping is being designed by Wirtz International in Antwerp.

This first phase of the project takes the form of a comb-shaped building, a carpet accompanying the topography towards the lake, creating generous terraces and intertwining the built volumes and green outdoor spaces.


The four built strips are arranged perpendicular to SICPA's existing headquarters, located to the north of the site. The five floors are connected and distributed by walkways, while a transverse axis distributes the ground floor from the main entrance located in the centre, along the axis.

The main challenge of the project was to work within a defined envelope and volume, while preserving the qualities of the initial authorised project – originally intended for laboratories – in order to turn them into an asset for the new programme, which is dedicated to office space.


It is no longer a question of building an extension to SICPA's headquarters, but of completing the first stage of an independent campus requiring its own access and its own services and support, while maintaining a functional link with the existing building.

The 4m floor heights, originally planned for the laboratories, are maintained, providing 30,000 m² of office space with a generous spatiality, enhanced by an abundance of natural light.

The main and transverse distribution on the ground floor has been reworked and reinforced in its programming. It houses a series of common areas, conference rooms, meeting places and catering areas such as cafeterias. A main restaurant is located on the lower ground floor, extending onto one of the patios. A 100-seat auditorium completes the conference room facilities.


The envelope consists of curtain walls bordered by walkways protected by sunshades. This simple and proven system allows for generous views from the workspaces onto the green spaces between the buildings, as well as the more distant landscape.

The abundant vegetation in the patios and terraces is complemented by the landscaping that surrounds the site. In total, around 100 trees of 23 different species have been planted in and around this first phase of the campus, providing landscaped areas open to all users of the site.

The campus has been awarded the Minergie P label for its energy-efficient design and the significant share of renewable energies in its energy mix, with 1,300 photovoltaic panels on the roof covering 20% of the building's energy needs. The campus is connected to district heating with a new-generation system that will guarantee around 80% renewable energy from 2024. Approximately 70% of the reinforced concrete is recycled, with recycled aggregates mainly recovered from the demolition of the buildings that previously occupied the site.

The campus is very well connected to public transport. Malley station is a 5-minute walk away, and several bus routes serve the site. From 2025, the future tram line will include a stop a few metres from the main entrance.
An underground bicycle parking facility (with a capacity of 400 bicycles) is integrated into the site.
