The setting? A heritage site with character. On the edge of Delft’s historic city centre, the former Faculty of Mining Engineering building from 1912 is being given a new lease of life. Fokkema & Partners is leading the renovation of this Neo-Renaissance monument—soon to be the second Paris-Proof heritage building in the Netherlands—transforming it into a future-proof working environment where history and innovation go hand in hand. In spring 2025, the doors will open to around 800 employees relocating from The Hague and Rotterdam. At the heart of the building, the two atria—once lush inner gardens—will once again connect to the Hortus Botanicus. An innovative floating roof structure spans the space between the courtyards, creating the architectural crown jewel of the design. Beneath this canopy, inviting meeting areas emerge, linking past and present to the future in a unique interplay of heritage and renewal.
Paris-Proof national heritage
Modernising and making the building more sustainable while respecting its monumental character requires a tailored approach. Braaksma & Roos Architects joined forces with specialists from Royal HaskoningDHV to develop smart solutions that future-proof the building. A new roof transforms the inner gardens into two contemporary atria. The interior design also supports sustainability goals. The accessible layout was created entirely with circular principles in mind. Special spaces have been designed using repurposed Dejo grilles and demountable timber structures. Together with RHDHV, an inventory was made of furniture that could be reused, was durable, sourced responsibly, and had the smallest possible carbon footprint. Even old lockers found a second life, transformed into bookcases in the library.
The ‘Collaborate’ atrium is designed for teamwork in a forward-looking environment
Collaborate & Connect
Each atrium has a unique function. A central coffee bar topped with a striking light installation in the' Connect' atrium makes the space welcoming and informal, perfect for spontaneous encounters and conversations. This atrium also houses the restaurant, where staff and visitors can enjoy healthy meals in an inspiring setting. The ‘Collaborate’ atrium is designed for teamwork in a forward-looking environment. It reflects Royal HaskoningDHV’s innovative DNA with flexible workspaces, meeting areas, and presentation zones. That DNA is also visible in details like the 3d-printed reception desk at the entrance.
A historical twist
The corridors and staircases of high historical value, have also been carefully reimagined by Fokkema & Partners. With respect for the past, a contemporary, abstract visual identity was created to honour the building’s legacy. Archival and on-site research uncovered original decorative elements such as wallpaper and dark-toned wainscoting. One of these—a deep red dot pattern—served as the inspiration for a new graphic signage concept. These subtle spheres now adorn the panelling and provide a clear, visually appealing wayfinding system throughout the building.
