Designing from the Cross-Section

The Subsurface as a Building Block for the Future-Proof City

The approach to urban transformation tasks is undergoing a major overhaul. After all, there is insufficient space to accommodate today’s major challenges – in the areas of climate, energy, circular economy, mobility and housing. It is high time we learned to look at our cities through three-dimensional glasses and to view the public space and buildings in relation to the subsurface. By tackling tasks from the cross-section (instead of the plan view), new and surprising solutions are brought to the table, which not only lead to an improvement of the living environment but also encourage multifunctional use of space.

Urban design, architecture, and landscape architecture student teams within the City of the Future Lab, and multidisciplinary design teams from practice have set to work in Amsterdam, Leuven, Maastricht, Mechelen, Ostend and Rotterdam. Together with academic and municipal experts, they have developed design propositions and exemplary solutions for city making in times of major transitions, and they have reflected on the importance of the subsurface and designing from the cross-section.

This design research resulted in a publication in Dutch. ‘Ontwerpen vanuit de Doorsnede’is the result of a collaboration between TU Delft, the COB Platform of Subsurface Construction, the Environmental Department of the Flemish Government, and the Delta Metropolis Association.

City x Space: Cross-Section Thinking

How can the integral and multifunctional use of public space, subsurface, and buildings -within a densified urban environment – create space and value that contribute to an attractive and future-proof living environment?

“This seminal question generates various answers depending on the specific context and location of asking. International interdisciplinary students from Delft University of Technology have outlined various design solutions. Manifest in all cases are the spatial bottlenecks on the level of public space. Connecting the intervention areas with the surrounding socio-spatial networks, therefore, forms the basis of all solutions. In addition, in the densification challenges we see the attention for the multi-layered space: on the one hand, a train or metro station, for example, generates flows of people at several levels; on the other hand, building in higher densities and/or living and working in collectives, generates new shared spaces.” As Maurice Harteveld explains in the exhibition; “The hybridization of the urban and architectural program also requires a cross-section thinking. This can be seen in future-proofing both large-scale sports or industrial areas, as well as small-scale residential houses in neighborhoods where work is shifting to local entrepreneurs and home workers. Finally, the subsurface plays an important role in greening the living environment and in water storage.”
