Alder Architects is a multidisciplinary practice based in Dublin & Cork. We enjoy applying our design skills to projects at all scales and therefore do not specialise in a particular building type - instead focusing on inventive use of materials and light. We place a strong emphasis on collaboration and participation with clients, communities and artists. Commissions to date have included new residential & commercial buildings, extensions to existing structures, workplace design and public installations.
