Led by brothers Manuel and Francisco Aires Mateus, the Lisbon-based architecture studio Aires Mateus is known for its wide range of work, from urban masterplans to intimate interior designs. Grounded in collaboration, each project evolves through close dialogue, from concept to completion, reflecting their belief that architecture must never be decontextualised. This issue explores their philosophy, process, and commitment to architecture as a cultural and social act. Featured are key projects such as the refurbishment of Variedades Theatre, Pateos Guest Houses, House in Monzaraz, MUDAC Lausanne, and more. A conversation with the architects adds further insight.
