The project is located on a 100 sq.wah plot of land purchased by two siblings near the condominium where they currently live, with the intention of building two houses—one for the younger sister and one for the older brother, who lives with his family and a young child. Both siblings previously lived in a two-storey wooden house in Thonburi before relocating, and they plan to have their parents live with them in the future.

The design concept focuses on preserving the spirit of the original wooden house where the siblings once lived. A central courtyard is introduced to connect the two houses, with all courtyard walls clad in wood to recall the atmosphere of the former home. Timber structures are also used throughout the courtyard and extended into the areas that connect to both houses, while the main residential volumes are constructed in concrete. Each house has a distinct spatial layout responding to the lifestyle of its occupants.

The building form is generated by dividing the site diagonally into two parts and flipping the geometry to create the sectional profile of the houses. Interlocking mono-pitched roofs are used to allow both houses to receive natural light and ventilation without blocking one another. Openings are designed to draw wind from the front of the site through the houses into the central courtyard, where a small bridge connects the two buildings.

The exterior elevations are kept simple, in line with the homeowners’ preferences, who were actively involved in proposing the desired image of the house. The architect focused on designing interior spaces that resemble narrow alleys and small passages commonly found in Thonburi communities.

The project is conceived as a Community House, where everyone takes part in the design and shares daily life together, reflecting the way the siblings grew up in their childhood home.
