About the project

In the heart of Lisbon, above Marquês de Pombal, Bow appears as a residential icon defined by rhythm, curve, and transparency. Designed by Ana Costa Arquitectura and developed by Prime Portugal, it reinterprets Lisbon’s modernism with sculptural softness. The façade, with rounded corners and a gentle convexity, breaks the grid and bows out as if talking to the city. Slim profiles frame deep bays with OTIIMA’s minimal systems, including custom curved glass that follows the organic shape, blurring the lines between architecture and atmosphere.

Inside, the architecture continues in bright, fluid spaces where openness and intimacy coexist. Bow features the OTIIMA Plus system, whose minimal frames disappear to let in the light and views. The bespoke curved glass reinforces the building’s sculptural flow, while the Invisible Lock and Horizontal Meyer Lock details make the experience seamless and tactile. Bow is an invitation to the city, to Lisbon’s horizons, air, and light into daily life.
