Duarte Caldas . Architecture Design is a Lisbon-based studio established in 2014, focused on architecture, interiors, furniture and light design.

The practice strives to highlight the inherent qualities of each space by enhancing them with unique, custom-made solutions. Technically, economically and culturally aware, our projects range from bespoke furniture or site-specific installations to residential, commercial and hospitality spaces.
