UB To Open Two New Diagonal Buildings in 2029

The project will concentrate teaching and health research on the Diagonal to form a major scientific hub using prefabricated near‑zero energy buildings funded by the university and the Catalan government.

Overview

  • On Monday, November 9, 2026 the Universitat de Barcelona and the Generalitat confirmed the programme and timeline with construction due to start in late 2027 and both buildings opening in 2029.
  • The academic building will be a nine‑storey Faculty of Mathematics and Informatics with about 14,000 m² while the health research centre will be six storeys and roughly 10,000 m² organized around 90 m² modular labs.
  • The joint budget has risen from earlier estimates to about €71–71.5 million and funding is channelled through the Institut Català del Sòl with costs split between the UB campus and the Generalitat.
  • Architect teams presented industrialised, prefabricated designs that target near‑zero energy use and include photovoltaic roofs, geothermal and aerothermal climate systems, bioclimatic atria and rapid modular lab fit‑outs.
  • Some nearby residents have objected to the height and volumetry and warned of pressure on services and mobility, but municipal approvals stand and the project is framed as part of a decade‑long plan to centralize campus activity around the future Campus Clínic‑UB.
