Dive into the South Atlantic from this concrete coastal home

Set on a granite outcrop in Ribeira Bay, this house by Pritzker Prize-winning architect Paulo Mendes da Rocha occupies a narrow peninsula with uninterrupted views across the water to Ilha Redonda and the mountains of the Serra da Bocaina.

Completed as a private residence, the project positions itself directly within the Atlantic Forest, with the structure extending outward over the sea. The house is formed from exposed concrete and glass, supported by four pillars anchored into the rock. A flat concrete roof spans the plan, while continuous glazing opens the interiors to the surrounding landscape. Living spaces are arranged as a single, open volume, punctuated by cylindrical concrete columns, with bedrooms set back in more enclosed zones. Timber shutters and joinery introduce a softer material layer against the concrete frame.

Externally, decks and pathways trace the contours of the site, connecting the house to the water’s edge. The property includes direct access to the sea, with calm conditions suitable for swimming and boating, as well as a private dock.

Embedded in the rock and extending over the water, the house reflects Mendes da Rocha’s approach to structure as landscape — an architecture defined as much by its setting as its form.

It’s being sold with price on application via the owner. For more details contact sama.raquelgerber@gmail.com
