About Single Wall Wohnhaus

Single Wall ist ein Wohnhaus in Angra dos Reis, Brasilien. Das Haus wird von einer durchgehenden, 80 Meter langen Wand aus gepresstem Bambus organisiert. Die Wand trennt Freizeit- und Servicebereiche, verbirgt Technikräume und trägt das aufgeständerte Schlafzimmervolumen. Sichtbeton, gepresster Bambus und brasilianischer Marmor sind die wesentlichen Materialien. Vorgespannter Beton ermöglicht eine stützenfreie Spannweite von 12,5 Metern und eine Auskragung von 6,5 Metern. Die Glaselemente lassen sich vollständig zurückschieben und verbinden Innen- und Außenraum. Querlüftung, Tageslicht und Verschattung sorgen für Komfort ohne technische Anlagen.

Behind the Design

Press Kit

Credits, team members and technical details provided by the designer.

Unique Properties: The project is structured by a single architectural gesture: an 80 meter long bamboo wall that organizes the program, separates leisure and service areas, supports the suspended bedroom volume, and conceals technical spaces. The architecture celebrates raw materiality, making exposed concrete, pressed bamboo, and Brazilian marble the protagonists of the space.
Dimensions & Packaging: Total area: 960 square meters
Free span: 12.5 meters
Cantilever: 6.5 meters
Continuous bamboo wall: 80 meters
Structural system: Post tensioned concrete
Material composition: Exposed concrete, pressed bamboo, Brazilian marble.
Tags: minimalist architecture, contemporary house, exposed concrete, bamboo wall, material honesty, seamless integration, landscape driven design, structural innovation, sustainability
Production Technology: The project combines advanced structural techniques with vernacular construction methods. The twelve point five meter span and six point five meter cantilever are achieved through post tensioning. Concrete is shaped using ribbed formwork and raw wood props. The bamboo wall, produced in China, serves both structural and aesthetic functions. High performance glazing systems allow full retraction of the glass panels.
Design Challenge: The main challenge was to preserve the conceptual essence throughout the construction process. Formal purity demanded extreme precision in every detail, from carpentry to material junctions. Visual continuity and conceptual integrity were only possible through rigorous control and conscious decisions. The result invites reflection: why do we still overcomplicate architecture?
Research: This research explores the relationship between linearity, functional concealment, and spatial fluidity. The eighty meter wall organizes the program and expands the perception of space. Structural solutions such as post tensioning were combined with vernacular techniques like ribbed concrete and pressed bamboo. Material continuity and constructive efficiency reinforce interior and exterior integration.
Inspiration: Situated between the mountains and the sea, the architecture emerges as a harmonious response to the landscape. Nature invites full openness, while dense vegetation protects privacy. The program follows a hospitality-inspired logic, where the spatial experience is continuous and service areas remain hidden. The house was designed to offer a contemplative and sensory immersion, without visual or functional barriers.
Project Duration: The project was conceived between 2021 and 2022 in Curitiba, and built between 2022 and 2024. Located in Angra dos Reis, the residence integrates with the tropical landscape, using its natural conditions to define the architectural approach from the beginning of the design process.
Operation Flow: Circulation is defined by a single continuous wall that separates social access from service areas. The path naturally leads to the suspended bedrooms, with no visual barriers. Glass panels fully retract, blending interior and exterior. Cross ventilation, natural light, and strategic shading ensure environmental comfort without the need for artificial systems.
