Prologue

Taoyuan Village, located in Qimen County, Anhui Province, is a classic example of an ancient Huizhou settlement. This project sits at a corner near the village entrance and is home to the only café in the village. Surrounded on three sides by neighboring buildings, the café faces a mountain wall on one side and opens toward a relatively spacious triangular courtyard.

▲ Original state

Originally a farmhouse, Dingwu is situated close to the village’s main stone road. Its new role is to serve as a public space catering to tourism in Taoyuan Village, resulting in the creation of a rural café.

The renovation preserves the original land boundaries, main entrance, roof height, and the traditional roof drainage direction. Given the enclosed, inward-facing layout, the design focuses on creating a welcoming interior courtyard space.

The Charm of the ‘Beauty Leaning’

The “Meiren Kao” (Beauty Leaning) is a distinctive wall element found in ancient Huizhou residences, positioned at the threshold between indoors and outdoors. Unlike standard doors and windows, it allows a person to lean comfortably inside. Its poetic form earned it the name “beauty leaning.” In the abandoned house, this feature is further extended to create a unified grey space combining the eaves, supporting windows, and integrated seating.

Facing outward, metal diagonal columns support the eaves and seamlessly integrate with metal backrests. Inside, the design creates a resting space by combining “support” for the window and “removal” of the stool. When closed, this assembly forms a complete wall.

‘Support’ and ‘Pick’

Diagonal supports offer a simple yet elegant way to transfer load. Within the invisible vertical gravity field, diagonal structures appear dynamic and intriguing. Traditional Chinese homes incorporate “supporting and removing windows,” which open horizontally via slant supports—lifting the window is called “support,” while pulling it down is “pick.” Dingwu draws inspiration from these ancient techniques, exploring a building system based on diagonal support relationships.

▲ Conceptual intention

Beam and Column Integration

In traditional Chinese architecture, beams and columns form the building’s skeleton and heavily influence the space’s atmosphere and rhythm. Structurally, inclined shuttle columns and melon seed-shaped beams support the double-sloped roof. Proportionally, the design continues the Huizhou tradition of “thick beams and slender columns.” Two shuttle columns run diagonally from the first floor through the second, supporting the roof and creating a transparent spatial connection between the two floors. This “beam and column integration” showcases the craftsmanship of diagonal support and joinery.

The double-sloped roof, supported by melon seed-shaped beams, is connected by slender metal hooks, allowing sunlight to filter through narrow gaps. The angle of the solid diagonal columns and the changing light throughout the day create a poetic interplay of time—both constant and fleeting.

Support and Remove the Staircase

The staircase is part of the inclined column system. As the columns extend upward, the diagonal supports vary in thickness and are connected top to bottom by slender metal wires. The stairs are entirely detached from the ground and floor slabs, enhancing a sense of structural lightness and mystery. This lifted staircase embodies another “physical” expression of diagonal support and hooked connections.

‘Support Platform’ and ‘Remove Fence’

The storage tabletop extends from the wall via diagonal support and is constructed with semi-transparent triangular plexiglass to form a platform. The second-floor railing handrails also feature inclined connections. These abutments and fences represent the “small carpentry” elements of diagonal support and linkage.

Craftsmanship

Dingwu employs modern laminated wood technology, which enhances the strength and durability compared to traditional timber. Robust metal components replace traditional mortise and tenon joints at critical connections. This separation of beams and columns, as well as columns from foundations, optimizes the wooden structure’s efficiency and clarity.
