About this project

Kolffpad is a large new students’ complex that has been under construction in the Bio Science Park in Leiden since mid-September 2021. You will soon be able to live in a beautiful, green and park-like campus area, within a new construction with many facilities for students. The university, University of Applied Sciences, and cosy Leiden centre are nearby.

The units

A total of 289 self-contained units will be available. So you will have a private front door, shower, toilet and kitchen. The majority of the units (248) will be 21 or 22 m2. The other units (41) will be somewhat larger: 27 m2


The complex will include excellent facilities for residents. This concerns three beautifully furnished common rooms, including a game & play room, a study café and a study room. All of these will be furnished with input from students.

We held a workshop for this last year, within which students could indicate what they think is important for the common rooms in the future complex. From that workshop it primarily appeared that there was a large preference for a good combination for the possibility to study and enjoy relaxing together. For example, students asked us for a suitable space where you can study, furniture and equipment for games (such as a foosball table, pool table, games, etc.) good movable furniture so that the layout could be changed for studying, watching a football game or just lounging as required, good coffee from a professional coffee machine, the possibility to cook together in a larger group and an outdoor picnic table.

DUWO will try to organise the spaces according to the students’ ideas as much as possible.

And the more practical facilities such as laundry facilities and covered (double-layer) bicycle storage will also be present.

The surroundings

The surroundings of the new students’ complex... This is mainly greenery! The new development complex is located on Kolffpad Street in a redeveloped green and park-like campus area, the Bio Science Park. It is a fun place to live. Because in addition to greenery, the surroundings are lively and bustling. The atmosphere breathes knowledge, science, innovation, research and education. With space for a hundred knowledge institutes and companies from the biotechnology sector, the area is the largest Life Science cluster in the Netherlands. Many companies are startups where young graduates work. Depending on your study programme, you may sit in the middle of your future there.

And it terms of accessibility, you are close to everything: university complexes, University of Applied Sciences, Leiden Central Station and the city centre are all nearby.  


Nearly everything about the new Kolffpad students’ complex is extremely sustainable. It is additionally located in a very sustainable environment as construction in the Bio Life Science Park is nature-inclusive. This primarily means that there are many applications for climate adaptation and biodiversity. The students’ complex is then also built from that starting point. For example, the building will have a green roof (with sedum plants or stonecrop), which provides rainwater buffering, air purification, reduction of urban heat stress and biodiversity. The roof itself will house insect hotels to attract bees, butterflies and other insects. The ground floor and façades will have greenery and nesting boxes for bats, house sparrows and common swifts. Who knows, they may soon fly past your window... And because of the connection to district heating, the complex will be fully gas-free. The tenants will cook electrically with electricity that is generated by solar panels.

Design and construction

The plan for the Kolffpad complex has been designed by Klunder Architects of Rotterdam. The construction will be carried out by Waal Bouw. The contractor is currently busy with the preparatory work, such as creating a temporary bridge for building traffic from Sandifortdreef Street. Construction started in September 2021 and is expected to be completed by mid-2023. 

Contract and rental prices

As like in all of DUWO’s student housing, you will receive a campus rental contract here.This means that you can live here during your entire study programme, but you must move to another residence six months after you have graduated.

The rental prices are not yet known at this time, but they will be affordable for students in any case. The majority of the units are destined for students under 23 years old, and the remaining units will be for students 23 years of age and above. Housing benefits are possible for all units.

Kolffpad presentation

In July 2021, DUWO organised an information meeting with the contractor Waal for neighbours regarding the upcoming construction activities. The presentation can be found here: VIEUW THE PRESENTATION
