The 2025 Horizon Europe calls under the New European Bauhaus (NEB) initiative open on 6 May 2025 and close on 12 November 2025 at 17:00 CET. They aim to foster sustainable, inclusive, and aesthetic transformations in the built environment. 

HORIZON-NEB-2025-01-BUSINESS-01 focuses on renovating buildings through design for adaptability and disassembly. The goal is to extend building lifespans, enable reuse of components, and reduce construction waste, aligning with circular economy principles.
