Rotterdam ROCKS! by MVRDV is a proposed cultural and public building on the south bank of the Maas in Rotterdam, conceived as a vertical extension of the river landscape with exhibition spaces, hospitality, event facilities, planted terraces, public routes, and ecological facade systems integrated into a compact stack of rounded volumes.

Our first step in approaching this design was to expand the brief. We need to reduce carbon dioxide emissions and to create inclusive spaces for people, trees, plants, for water, air, and for animal habitats, balancing the need for new built space with new landscapes to compensate our ecological impact.

Urban Context and the Vertical Extension of the Maas Landscape
Rotterdam ROCKS! is positioned at a significant point in the spatial reorganization of Rotterdam South, where former harbor land is being reworked into the Waterkant district. The site sits near the landing of the city’s planned third bridge across the Maas, placing the building between infrastructure, riverfront public space, and a future field of housing, schools, workspaces, and cultural programs. Rather than treating the waterfront as a boundary condition, the proposal uses the river edge as the basis for its architectural section.
The massing extends the tidal park upward through a sequence of planted terraces, exterior stairs, observation areas, and water-retaining surfaces. This strategy shifts the idea of landscape from horizontal ground plane to occupied vertical infrastructure. The building acts less as an isolated object than as a thickened edge condition, mediating between the dense urban blocks behind it and the shifting ecological systems of the Maas.
At approximately 60 meters in height, the project uses elevation to frame views across the river, the skyline, and the new district. Its large voids and porous edges prevent the volume from reading as a sealed tower, while still producing a strong presence at the bridgehead. The proposed public route functions as an urban device, making the river landscape accessible above ground level and turning the facade into a civic surface rather than a perimeter.
Stacked Volumes, Caves, and Circulation
The design is organized as seven rounded volumes arranged into two interlinked vertical stacks. These forms contain the main program while generating the spatial byproducts that define the project: terraces, overhangs, framed openings, deep voids, and cave-like interiors. The rock metaphor is not simply visual. It provides a way to reconcile compact stacking with irregular exterior surfaces that can host planting, circulation, and microhabitats.
Circulation is structured through three principal routes. One route serves the exhibition sequence, guiding visitors through immersive spaces within the building’s interior caverns. A second route organizes the hospitality and support programs, including hotel and restaurant functions. A third route climbs the exterior, connecting terraces and viewpoints and allowing parts of the building to function as a public extension of the riverfront park. This separation of routes helps reduce the program’s complexity while creating moments of visual overlap among visitors, hotel guests, exhibition spaces, and the surrounding city.
The interior spaces rely on a deliberate contrast between enclosure and exposure. Cavernous halls, arched openings, textured surfaces, projections, and controlled light produce an atmosphere closer to an artificial grotto than a conventional gallery. At intervals, the route breaks outward toward terraces and panoramic windows, replacing immersive digital environments with views of Rotterdam and the Maas. This alternation gives the architecture a narrative rhythm, where interior spectacle is repeatedly tested against the actual urban and environmental context outside.
Program as an Architectural Framework
The building combines a 5,000 m2 immersive exhibition, a 200-room hotel, event areas, offices, food hall, restaurant, observation deck, gift shop, and public circulation. The challenge is less the coexistence of these functions than their vertical compression within a single figure. MVRDV addresses this through a compact organization in which programmatic density is opened by voids, public decks, and planted surfaces, allowing the building to accommodate large internal volumes without becoming a closed block.
Public access is treated as a spatial principle rather than a secondary amenity. The exterior path, terraces, and roof areas extend the civic realm upward and make parts of the building available beyond ticketed or private programs. This is a critical move in a project whose environmental ambitions depend on public legibility. If the building is to communicate questions of climate, biodiversity, and resource use, its systems must be encountered spatially rather than hidden behind representational displays.
The exhibition and event spaces are embedded within the rounded volumes, producing a series of interiors shaped by contrast. Digital projection environments occupy darkened cave rooms, while auditoria and hospitality spaces open through large oval or lens-shaped windows toward the water. Raw textured walls, warm interior tones, and framed exterior views create a tension between constructed geology and media infrastructure. The result is an architecture that uses program not as a neutral container, but as a framework for choreographing movement between information, atmosphere, and landscape.
Ecological Skin, Material Strategy, and Environmental Monitoring
The facade is conceived as a porous inhabited surface, with pockets, channels, cavities, terraces, and planted recesses designed to hold soil, retain water, support vegetation, and provide nesting opportunities for urban species. Its texture varies according to orientation and exposure, shifting from planted horizontal terraces to angled surfaces, vertical pockets, and protected overhangs. This approach attempts to move beyond the green facade as an image by giving the envelope specific spatial and ecological functions.
Environmental analysis informs the distribution of six proposed micro-biomes, including coastal grassland plateau, sun-exposed roof meadow, dune edge, wet terrace meadow, woodland edge, and shaded moss ecotone. These zones respond to daylight, wind, runoff, concavity, inclination, height, and solar exposure. Such precision is essential if the project’s ecological claims are to become more than surface treatment. The facade’s performance will depend on long-term maintenance, plant succession, irrigation, substrate depth, and the ability of nesting cavities and moisture layers to remain viable under urban conditions.
The material strategy proposes reducing embodied carbon through reused steel, lower-carbon concrete, bio-based components, modular facade elements, and design for disassembly. Photovoltaic areas of approximately 2,500 m2, rainwater buffering, greywater reuse, heat pump systems, and adaptive climate zones form part of the environmental framework. A real-time monitoring system is intended to display data on energy, water, air quality, biodiversity, comfort, and material performance. As an architectural instrument, this monitor is significant because it makes environmental performance visible and revisable, allowing the building’s claims to be measured over time rather than fixed at the moment of completion.
