Ana Costa Arquitetura e Design

Ana Costa Arquitectura e Design is a Lisbon-based architecture and design studio with more than 50 years of history. Rooted in Atelier Daciano da Costa, the office was founded in 1959 by Daciano da Costa (1930–2005), considered by many one of the pioneers of Design in Portugal.

As a pioneer, he developed many aspects of the Design practice: his famous works range from important public and cultural buildings—such as the Fundação Calouste Gulbenkian, the Centro Cultural de Belém, and the Biblioteca Nacional—to innovative furniture systems that revolutionized the office industry, as well as hotel design, urban design, and public art.

Since 2005, architect Ana Costa has continued this legacy through Ana Costa Arquitectura e Design. With expertise in the rehabilitation of historical buildings, contemporary high-quality design for residential, commercial, and hospitality projects, the studio has also been growing in corporate “built-to-suit” design, as well as transportation and urban design.

In 2025, Ana Costa was awarded the Prémio Valmor e Municipal de Arquitetura 2021 for the rehabilitation of Estação Sul e Sueste in Lisbon.

What may be considered as the “brand”—the differentiating factor—is a commitment to “a way of making,” which, against all trends of mass production, cultivates the idea of “proximity.” This means recognizing the importance of the creative process and the value of “designing to suit”—the idea of uniqueness and customization in the ever-growing complexity of project management.

The office design background has had a major influence in every project, no matter its size or end use. This approach, from inside out, with attention to materials, color, light, and comfort, as well as sustainability, is reflected in this “way of making.”
