This year marks a turning point where sustainability is no longer a niche interest but the central paradigm in architecture and design across Europe. Whether retrofitting historic structures, greening urban rooftops, integrating AI with living systems, or weaving tradition with innovation, Europe’s professional community is crystallizing a future-built environment that’s ecological, equitable, and intelligent.
Sustainability in design is evolving from a buzzword to a design imperative in 2025. Across the UK and Europe, architects, designers, policymakers, and researchers are convening to explore the intersection of environment, aesthetics, and function. Here’s a complete guide to key events in sustainable architecture and interior design happening in 2025, including conferences, exhibitions, biennales, and award shows — each with a link to explore or register.
