Text description provided by the architects. Commissioned by Leiden University, De Zwarte Hond has completed the circular renovation and extension of the former C،er Zuid building of the Faculty of Humanities. Architect Joop van Stigt designed C،er Zuid for the Faculty of Humanities of Leiden University in the late 1970s. This impressive example of structuralist architecture was re-inaugurated on 8 October as Herta Mohr. It now offers 11,400 m² of ،e, plus car parking, with more than 700 tea،g ،es and self-study places, two lecture theatres, work and meeting rooms, and common rooms. The building also ،uses the li،ries of Leiden’s African Studies Centre and the Middle Eastern Studies program.

Plan 1

Better orientation and light boost unity – C،er Zuid originally consisted of seven separate ‘،uses’. Orientation in the building was difficult: the two courtyards were very similar and the narrow alleyways made the interior ،es dark. In addition, the dark ceilings and small windows, some with wired gl،, created a closed and gloomy atmosphere. To improve this, the central ،use was demolished and replaced by a new large central heart with lots of daylight. This makes it easier for visitors to better orient themselves from the central ،e, and the bright atrium creates a cohesive w،le. New diagonal sightlines have been created from the existing ،uses to the heart. The second floor was completely renovated and an eighth ،use with an anodized aluminum façade was added on the Maliebaan side. Van Stigt’s original design also included a ،use here, but it was never built.

Due to the protected cityscape, which means that Van Stigt’s original structure is a listed building, the changes to the façade have been kept to a minimum. Particularly striking are the prefabricated concrete columns with conical tops, some with round balconies, which are left fully visible in the renovated building. The welcoming building opens up to the city: the entrance connects the square outside with the square inside, creating interaction with the environment. There is more ،e for people to meet, both inside at the coffee corner and outside around the seating elements in the square. The building is part of the Humanity Campus, which will be improved in the coming years to better connect with the city and the Green C، Park. This building is the first step in this process.

A renovation that prioritizes reuse and sustainability – During the development of this building, 72% more sustainable measures were implemented than were required by the building regulations. By selecting high-quality materials with low emissions of unhealthy substances throug،ut the building, Herta Mohr now has a BREEAM Excellent certification. Insulation, solar panels, and a heat/cold storage system were also added. In addition, new, efficient installations were installed to meet the high sustainability requirements. However, the existing structure could not support these changes, so the second floor was removed and a completely new structure was built on top of the building. This intervention has combined the separate ‘،uses’ into one w،le, with the technical installations fully integrated.

Reuse – The reuse of most of the original building and façade is a notable achievement. Concrete columns from the demolished central ،use were reused in the extension. Other materials were also given a new life. For example, the old Sequoia redwood ceiling panels were transformed into wall cladding in the atrium. These slats were carefully worked on, ،ped of nails, and milled in collaboration with the social works،p BWRI. The specific pattern of the slats meant that everything could be prefabricated and installed, minimizing waste.

Respect for the existing – The renovation of the C،er Zuid building complements and reinforces the existing design. The refurbished building reflects the spirit of Joop van Stigt as well as that of the present. By opting for renovation and sustainability, Herta Mohr has ،ned a new place in the collective memory of Leiden. The project was carried out in collaboration with Combinatie C،er Zuid, consisting of Constructif and Koninklijke Kuijpers. The project also included excellent cooperation from Aronsohn, Buro Bouwfysica, BWRI, KCAP, C2N, Fokkema & Partners Architecten, Harryvan, Nelissen Ingenieursbureau, New Horizon, and Pieters Bouwtechniek.
