FLAT12x stacks floating gardens for senior-living house in bangkok

Floating Garden House sits on compact plot in Bangkok

Located in Rama 9, Bangkok, the Floating Garden House for Seniors by FLAT12x is a three-story residence designed on a compact 70-square-wah urban plot. The project addresses spatial constraints through vertical organization, with cantilevered balconies that extend outward to create alternating garden terraces on each floor.

These balconies serve dual purposes: they provide space for small-scale gardening in a dense urban context and function as passive shading devices that protect the interiors from sun and rain in Bangkok’s tropical climate. Additional climate-responsive features include wide roof overhangs and aluminum lattice screens, which enhance ventilation, regulate daylight, and ensure privacy.

interior design by FLAT12x prioritizes senior living

The interior design prioritizes senior living by maintaining clear circulation, barrier-free layouts, and direct access to outdoor spaces on each level. Every floor integrates greenery, encouraging daily interaction with natural light and plants. A sustainable approach continues within the interior, where existing furniture has been repaired and reintroduced rather than replaced. The design team at FLAT12x restores tables, chairs, and the family’s bed for continued use, embedding memory and familiarity into the living environment while reducing waste.

By combining cantilevered garden balconies with adaptive reuse of materials, the house demonstrates how architecture can integrate climate-responsive design, sustainability, and well-being within the limitations of a compact urban site.
