In spatial planning, one focus is on hub development. The success of this focus is largely dependent on the quality of the node in which the different modes of transport converge: the so-called “transition moment”. Until recently, buildings that facilitate this transition have usually been considered as "transfer machine": a functional machine for processing passenger flows and the associated means of transport. More and more however, the transfer machines are evolving in to more than just pure functional machines.
Just like the new railway stations, P+R buildings are considered to be a catalyst for new developments in the immediate vicinity. P+R Kralingse Zoom is an example of this approach: no anonymous 'machine', but a building with a unique face, that offers comfortable routes for the transition between bike, car and metro and is also the starting point for the redevelopment of the Brain Park.
Ballast Nedam was selected by the Rotterdam municipality for the design and realization of a transferium, open to the public, with 1040 parking spaces, accessibility also via a specific zone for targeted groups and linked to the existing offer of public transport: metro, bus and people mover.
To this end, the architectural office ZJA designed a more than 175 meter long and 6-storey high building with an open character and a striking aluminium slat façade, with high ambitions regards the appearance as a striking business card for the entire area, and with light, colour and use of materials playing an important role. The building follows the curvature of the A16 and in doing so, emphasizes the identity of the building and its relationship with the motorway. Additionally, the building partially converts the metro and bus station into an underpass. The result is a striking node, which acts as a reference image for the high-end Brain Park office area. Social security was given a leading role in the design, for example by paying careful attention to the lighting levels, ensuring that clear and long sight lines contribute to a feeling of safety and a natural orientation, and by ensuring adequate transgression of daylight by incorporating a spacious loft.
Routing and recognition
P+R Kralingse Zoom is an important transport hub and sees many different flows of visitors. For several regional bus lines it’s their terminus, allowing travellers to continue their journey by metro. Motorists can park their cars and switch to public transport. A people mover connects the P+R with the business area Rivium in Capelle aan den IJssel. Optimal routing is designed to ensure a safe and friendly public building. This routing is organized in such a way that visitors to P+R Kralingse Zoom can be properly channelled, also during peak times The control zone of the metro station is fully integrated into the building and within a few minutes the visitor is transformed from motorist to public transport traveller.
The master plan is based on a ground level having been elevated to a level above two parking levels. The two parking levels form the green plinth of the building, a grid facade covered with overgrown niches. The above laying volume serves as an eye catcher seen from the A16. The special pattern in the horizontal slat façade reinforces this character. In the longitudinal façade, wave-like patterns have been designed, by positioning slat in a fixed and pre-determined position. This way, the interior is separated from the exterior, without closing the space, giving Brain Park and P+R Kralingse Zoom a recognizable face.
Flexibility and durability
The design is fully prepared for a future second phase, during which the garage can be easily extended to approximately 2,200 parking spaces. To accommodate this, the construction has been designed in such a way that no less than three extra levels can be added at a later stage. The entrance level of the transferium has a freestanding height of 4 meters. At a later stage, this part of the building can accommodate commercial spaces without the public accessibility being compromised.
The effects of P+R, like promoting public transport and relieving the inner city, do not only contribute to a sustainable environment. The building itself does so too, by for example linking rainwater drains to surface water, so relieving the sewers and by allowing the building to form a sound buffer between the motorway and the Brain Park.
