Diaz y Diaz Arquitectos

What Diaz y Diaz Arquitectos does

Díaz y Díaz Arquitectos is a privately held Galician architecture studio that delivers professional design services across residential, civic, healthcare, educational, hospitality, and public infrastructure typologies. Founded in 1998 and led by principals Gustavo Díaz García and Lucas Díaz Sierra, the firm operates from two offices in A Coruña (Galicia) and Pozuelo de Alarcón (Madrid), serving regional and national government bodies, port authorities, universities, private developers (Vía Celere, Metrovacesa, Acciona Inmobiliaria, Cupa Group), and individual clients across Spain, with select projects in France and Portugal.

The firm's technical core is architectural design and project execution, with accumulated proprietary expertise in energy-efficient and contextually integrated building solutions — including geothermal and photovoltaic net-zero energy design, heritage building energy retrofits (biomass boilers, centralized HVAC), and marine-environment double-skin facade engineering. The practice is structured around four service categories: Vivienda (residential), Equipamientos (public/private facilities), Rehabilitación (heritage rehabilitation), and Espacio Público (urban design and public infrastructure), with project scales ranging from small rehabilitations to ~150,000 m² hospital complex proposals.

The business model is fee-based professional services: revenue is earned on awarded commissions, sourced primarily through winning public tenders and architectural competitions (e.g., XXI COAG Award, LEAF Award 2011, UDC EI3 first prize), and secondarily through private developer and individual client commissions. There are no recurring revenue streams, no digital products, and no consumer-facing channels; the firm relies on competition wins, architectural press coverage, and repeat institutional relationships for business development.
