The RIAI Annual Conference 2025 at the RDS Dublin brought together over 2,000 delegates to focus on the role of architecture in cities, towns and neighbourhoods, with a strong emphasis on sustainable, affordable and people-focused development.

Opening the event, An Taoiseach Micheál Martin emphasised that architecture and planning are central to addressing Ireland's housing and climate challenges, stating that well-designed buildings and infrastructure are essential for resilient communities.

Over two days, leading Irish and international architects showcased approaches to housing affordability, urban renewal and climate-resilient infrastructure. Affordable housing and regeneration were key topics, with examples from Barcelona, Vienna, and Hackney presented by José Toral, Katharina Bayer, and Holly Lewis, respectively.

Infrastructure-focused projects also featured prominently. Dr Andrew Clancy presented the design-led Arklow Wastewater Treatment Plant, while Dr Gesa Matthes shared insights from HafenCity Hamburg, Europe's largest urban regeneration project. Brussels' Kristiaan Borret highlighted the importance of independent architectural oversight in urban planning, and Dutch architect Francine Houben of Mecanoo demonstrated how public buildings can foster civic pride and cultural inclusion.

Irish architectural practices and local authorities shared case studies in design-led planning. Valerie Mulvin FRIAI and Andrée Dargan FRIAI explored town and neighbourhood revival, while Sheila O'Donnell FRIAI and John Tuomey FRIAI detailed the East Bank urban renewal project in Stratford, London, incorporating V&A East and Sadler's Wells East. Peter McGovern of Henry J Lyons showcased the Ireland House Japan in Tokyo, combining the embassy, official residence, and offices for State bodies including Enterprise Ireland. Panels with Lawrence and Long, Boyd Cody Architects, and tún architecture highlighted sustainability, adaptive reuse, and community engagement in contemporary projects.

RIAI President Seán Mahon emphasised the long-term value of quality public buildings and infrastructure, noting that architects provide practical solutions to create sustainable, meaningful places for communities. He also called for increased prioritisation and resources to implement Ireland's National Policy on Architecture, Places for People.
