CTA Designs Annex in Vietnam with Curved Roof to Evoke Cave Sensation
CTA studio creates a unique design that brings nature into the living space.
1CTA's New Project in Vietnam
CTA studio has designed an annex for a house in Phu My, Vietnam. Named Casa Mac, the structure was conceived as a large, singular living space. The design is built around the idea of bringing nature into the interior. The building is surrounded by a vegetable garden and a koi pond. This approach aims to create a natural atmosphere while minimizing traditional home elements.
2Roof Design Evoking Cave Sensation
The most striking feature of Casa Mac is its curved, canopy-like roof. A long skylight runs through the center of the roof, and the light entering through it is filtered by perforated metal screens. CTA co-founder Nguyen Thanh explains that this design aims to evoke the sensation of being in a cave. The roof unites daily human activities and natural elements under a single shade canopy.
3Natural Materials and Minimalist Approach
Casa Mac's design incorporates raw and rustic materials. Exposed brick walls are complemented by a ceiling made of narrow wooden planks. The roof is covered with scale-shaped bitumen shingles. This material choice enhances the building's harmony with its natural surroundings. Partition walls and doors are kept to a minimum to create an open space feeling.
4Functional Layout of the Interior
Casa Mac's interior consists of a large area divided into different zones. The central area is segmented by green spaces. Two wide sets of steps connect the lower living, dining, and kitchen area to a slightly elevated workspace and jacuzzi. To the west, stone steps lead across the koi pond to a parking area.
5Connection and Transitions to the Main House
The annex is connected to the main house via two small pathways at the front and back. These pathways ensure seamless transitions while keeping the daily activities of the two households distinct. Narrow arched openings in the brick walls provide easy access to the main house. This design maintains connectivity while preserving the independence of both homes.
6Rest Room and WC Area
Instead of a traditional bedroom, Casa Mac features a rest room next to the WC. This area is designed as a temporary spot where friends can take a quick rest or sober up. This approach indicates that the building is not used as a conventional residence and offers a more flexible living space.
7CTA's Previous Projects
CTA studio previously designed a narrow house in Bien Hoa. In that project, folding doors and perforated screens were used to control light and ventilation. Additionally, the studio has a project featuring a house clad in reused scallop tiles. These projects showcase CTA's expertise in natural materials and innovative designs.
8Architectural Significance of Casa Mac
Casa Mac stands out as an example of design that brings nature into the interior and reinterprets traditional home elements. With its curved roof, exposed brick walls, and natural materials, this structure emphasizes the importance of creating living spaces in harmony with the natural environment in modern architecture. CTA's project offers a fresh perspective in architectural design.
