The Big Tech Decentring Urban Big Tech Clusters: From Exclusive Tech Valleys To Open Regional NetworksLeonardo Mühlestein, Vithursan Manoharan, and Alberto Früh

Zurich has imported the Silicon Valley economic model without adapting it to the fragility of a dense European fabric. This chapter analyses the friction between the global ambition of Big Tech and the physical reality of a city that cannot afford enclosed campuses. Through eye-level photography and comparative maps, we demonstrate how the Silicon Valley myth is producing a sterile spatial quality in Zurich, where corporate identity outweighs human scale, turning historic districts into mere logistics corridors for tech commuters.

In this chapter, we define the identities of the key players: The Big Tech represents control, infrastructure stability, and data protection, attracting economies avoiding spontaneity. Small Tech represents agility, seeking proximity and low costs as true social activators. We finbalise the chapter by reconstructung a settlement timeline to show how the saturation of the Zurich city centre has created a rigid spatial hierarchy.

The current tech clustering is in fact a fracture in the city. We consider the current segregation in terms of impact on labour market, gentrification, and impact on public life. We prove that Big Tech’s “control” has generated an invisible wall that empties the streets of interaction, neutrality, and urbanity making a beneficial decentralisation strategy urgent wich will positively reflect in the housing market.

We propose new strategic nodes for the relocation of tech clusters, based on the required conditions of a site such as tax attractiveness for corporations, accessibility ensured by public transport, population density as well as proximity to academia. In addition, low-cost space has to be available for Small Tech and the cluster has to have the potential to improve the neighbourhood. As a result, we shift from monofunctional centrality of the city centre to a polycentric urban network.

From the territorial strategy, we move to the architecture and propose a new typology, the multifunctional building, as the core architecture of the new hubs. The ground and first floors are porous to public functions. Above that, there are semipublic co-working offices, followed by private corporate offices.
