Selected interiors and spatial installations.

Spaces shaped through concept, materiality and a singular point of view.

Based in Costa Rica, Martēn Design approaches each residence as a complete environment—bringing spatial planning, interior architecture, custom elements, materiality, furniture and art under one creative direction, carried from the first drawing through execution.
