Bottom- Up NEBourhoods is an international and collaborative research project funded by Horizon Europe (the EU’s funding programme for research and innovation) for the period 2026-2029. Rooted in the New European Bauhaus (NEB) framework, Bottom-Up NEBourhoods depart from the idea that conventional top-down policies and technological solutions for Europe’s ecological and social transition have proven insufficient to deliver the envisioned outcomes. Building & construction, mobility, and land use remain carbon-intensive, resource-demanding, and often misaligned with the needs and values of local communities. Meaningful transformation ideally begins at the local level—within neighbourhoods, where questions of affordability, accessibility, cultural identity, belonging, and quality of life are most tangible.
