About Single Wall Inzu yo Kubamo
Single Wall ni inzu yo kubamo iherereye i Angra dos Reis, muri Berezile. Iyi nzu iteguwe hakoreshejwe urukuta rumwe rukomeza rw'imigano ikandagijwe, rufite uburebure bwa metero 80. Uru rukuta rutandukanya ahantu ho kuruhukira n'aho serivisi zitangirwa, ruhisha ahantu ha tekiniki, kandi rushyigikira igice cy'icyumba cyo kuraramo kimanitse mu kirere. Beto igaragara, imigano ikandagijwe, na marimari yo muri Berezile ni byo bikoresho by'ingenzi byakoreshejwe. Beto ikomejwe nyuma yo gutakwa (post tensioned concrete) ituma habaho umwanya ufunguye wa metero 12.5 n'igice kimanitse hanze cya metero 6.5. Ibirahure bishobora gukingurwa byose uko byakabaye, bigahuza imbere n'inyuma y'inzu. Umuyaga unyura mu mpande zombi, urumuri kamere, n'igicucu bituma habaho imibereho myiza nta bikoresho by'ubukorano bikoreshejwe.

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

- 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.
