Stacked volumes Organize the multi-level living space from an anonymous studio
Located in an established residential enclave in Bangkok, Siamoom home from anonymous studio conceived as one extension into an existing residence, introducing additional space while maintaining continuity with its surroundings. The project reexamines the conventional housing typologies through a design approach centered on curved geometry and spatial continuity.
Located adjacent to the original house, the new structure is defined by a series of curved lines that update both the plan and elevation. These curves act as spatial devices, allowing adjacent areas to remain connected without rigid separation. This approach creates a continuous relationship between the two buildings, while at the same time blurring the boundaries between architecture and space.

Continuous curves and stair-changing paths organize the house
The ground floor hosts common functions such as the living room, dining room, kitchen and an outdoor space that extends towards the original house. The private spaces, including the bedrooms, are arranged on the second and third floors. Curved geometries are introduced at key intersections, particularly along the front facade and corners near the edges of the property, reducing corner transitions and contributing to a more continuous spatial flow.
A hollow glass wall marks the junction between the new and existing structures. This transparent surface allows the exterior of the original house to extend into the new interior, forming a shared terrace between the two volumes. The gesture reinforces the “space sharing” concept of the project while increasing the penetration of daylight to the ground floor. Protruding eaves provide shading, mitigating solar gain along the glazing surface.
THE designers in the anonymous studio organize circulation to encourage movement within the home. The staircases connecting each level are placed in different locations, distributing circulation routes and evoking varied spatial experiences throughout the interior.

Wood, concrete and curvature define the continuity of the material
The choice of material emphasizes contrast and continuity. Timber is used extensively in touch points and visual accents, reflecting the client’s preference for natural materials. Dark-toned wood is applied to window frames, railings and exterior decking, contrasting with concrete walls and white exterior surfaces. Inside, lighter wood tones are used for floors, doors and furniture, contributing to a softer spatial atmosphere.
The exterior is finished in gray plaster that evokes raw concrete, with a slightly textured surface that adds depth. This contrasts with the interior, where smooth white walls create a more controlled and neutral environment. The interior palette combines light wood, gray and beige tones, creating visual continuity across all surfaces and furniture.
Curved geometry remains the main organizing principle throughout the work. The exterior and interior surfaces follow their respective radii, creating continuous spatial relationships between interior and exterior. This approach supports a fluid transition between the new and existing structures, enhancing the integration of common areas and the overall spatial coherence of the design.
