The water transport pontoon at Steenplein is due for replacement. A new 150-metre-long pontoon will be constructed, along with a new access bridge and waiting infrastructure. De Vlaamse Waterweg and AG Vespa are jointly delivering this future-oriented and high-quality water-based infrastructure.
The Steenplein pontoon is a key hub within Antwerp’s water mobility network. It connects the right bank to the left bank via the ferry service that docks there and also serves as a stop for DeWaterbus. Increasing usage and evolving needs require expansion and reconfiguration.
De Vlaamse Waterweg and AG Vespa opted for a completely new 150-metre pontoon, extending it by 50 metres compared to the existing structure. This improves accessibility, enhances user flows and boosts water mobility.
By positioning the access platform centrally, a clear and logical connection is created between Steenplein, the quays and the pontoon. Particular attention is paid to ease of use, comfort and safety for both pedestrians and cyclists.
The existing temporary access bridge, currently positioned perpendicular to the Scheldt quays, will be replaced by a new 70-metre bridge aligned parallel to the quays. This increases user comfort and convenience for all passengers. Waiting infrastructure is also integrated into the pontoon design.
During the concept phase, multiple design options were explored and assessed in consultation with various stakeholders.
A key feature of this project is the strong integration of engineering and architecture from the earliest design stages. By developing both disciplines in close interaction from the outset, both the structural logic and architectural expression were reduced to their essence. This integrated approach resulted in a clear, simple and self-evident design, where structure, use and spatial quality reinforce one another.
With a focus on spatial calm, open views towards the Scheldt and a sober, timeless design, the project fits seamlessly within the historical context of Het Steen and its surroundings.
The infrastructure is deliberately kept minimal, with low architectural elements that preserve sightlines between quay, square and water. The head of the stone slope is enhanced as a place to stay, a social anchor point and a hinge between Steenplein, the pontoon and the quays.
The robust maritime environment was a key driver in the choice of materials and structural design. The project is conceived as a modular and flexible system, composed of standardised elements that are durable, low-maintenance and future-proof.
The canopies, seating elements, wind screens and information systems follow the same logic, resulting in a coherent whole that is recognisable in its architectural expression while remaining adaptable and future-oriented.
SBE is responsible for the full study and design process, both technical and architectural. The assignment includes the design of the new pontoon, the reconfiguration of access and the access bridge, and the development of the waiting infrastructure. SBE also prepares the permit and tender dossiers and provides technical support during construction.
From Antwerp to India, SBE is taking steps in progress and innovation all over the world. Below you will find a selection of our most recent projects.
