BIM Architecture: Research and Design of Localized Jianghuai Village Houses by Kotu Architectural Design

Background

With the rapid urbanization, cityscapes have transformed significantly, while rural areas have gradually lost their vitality, leading to numerous “hollow villages.” The Weimei Motan Homestay Project is a regeneration initiative aimed at revitalizing such hollow villages. Located in Dawei Town, Baohe District, Hefei City, Anhui Province, the project is bordered by Feihe Wetland Park to the north and Chaohu Lake to the east, surrounded by farmland.

The designers drew inspiration from the cultural heritage of the Jianghuai region by extensively studying local materials. Their design respects the natural climate and construction traditions, using surrounding residential buildings as prototypes. Rather than strictly replicating traditional Jianghuai architecture’s appearance, volume, and scale, the design redefines the relationship between buildings and courtyards, streamlines circulation, and adapts spaces to new functional needs. Flexible modern techniques are employed to enrich the spatial hierarchy and architectural expression.

The Jianghuai region sits between the Yangtze and Huai Rivers, characterized by low mountains and hills. Jianghuai residential buildings blend the “courtyard style” of the northern Central Plains with the “hall, well, and tower style” of Huizhou architecture. The layouts tend to be compact and well-ordered, while architectural decoration emphasizes simplicity. Most structures are single-story, with some two-story buildings.

The homestay’s color palette predominantly features black, white, and gray. The exterior walls are painted white, complemented by gable roofs with modern minimalist cornices and small gray tiles, blending traditional charm with contemporary simplicity.

△ Main entrance

The building’s main entrance features a shallow water surface creating a semi-circular corridor that leads to the central structure—the “Lobby Bar.” This space exemplifies the typical “hall house” style of Jianghuai architecture and serves as a multifunctional public area for today’s homestay experience.

The corridors and bluestone pathways are integrated within varied spatial forms and boundaries, serving as dynamic connectors between buildings.

Based on a new spatial definition, usage requirements were carefully considered, employing flexible modern techniques to enhance the architectural and spatial hierarchy.

Spatial sequence and design philosophy

Chinese architectural tradition emphasizes “following the trend,” which refers both to the terrain and human potential. Regarding terrain, designs should conform to the local climate and lifestyle, respect elevation differences, and minimize environmental impact. Concerning human factors, the design must align with the target audience’s needs. The original site presented irregular elevation changes, and the architectural design harmoniously follows the slope.

Spatial expression

Building upon traditional Jianghuai architecture, large glass panels were introduced to avoid monotony, allowing natural light to fill interiors and creating varied, transparent spaces.

Summary

As the saying goes, “One place nurtures its own people.” The homestay design focuses on enabling visitors to immerse themselves in the unique local culture and natural scenery. While Jianghuai architecture is influenced by northern and southern styles, it has developed distinct characteristics over time. This rural revitalization project embraces the local expression of Jianghuai dwellings, explores their cultural value, summarizes design techniques, and contributes to the ongoing development of Jianghuai architectural design.
