BIM Architecture: Designing Bagu Su Ji in Dianjiang, Chongqing – A Harmonious Blend of Mountain and Rice Field Living

Venue: A Natural Village at 800 Meters Altitude with Views of the County Town

In 2019, I was invited by the local government to visit Dianjiang for the first time. Dianjiang County is located about 120 kilometers northeast of Chongqing’s main urban area. The project site is situated in Leijiawan, a natural village cluster within Shilu Village, Guiyang Street, Dianjiang County. Nestled in the Mingyue Mountain Range at roughly 800 meters above sea level, the area offers a cool summer climate, making it an ideal escape from the heat.

To the west of the site lies a higher mountain, flanked by small hills on both sides. To the southeast, a gap in the terrain reveals a view of the county town, located 8 kilometers away, enhancing the site’s natural advantages. Of particular interest is a horseshoe-shaped rice field on the property, around which the original villagers’ lives and agricultural activities revolve. The half-acre plot supports a single cow, with villagers working from dawn to dusk.

Beyond the peaceful rural cultural landscape, the area also hosts historical landmarks, the most famous being the Bashu Ancient Road. Legend has it this was the route used to transport lychees for Yang Guifei, earning it the nickname “Lychee Ancient Road.” Climbing the stairs along the path, visitors can still see boundary markers from that era and cliff carvings left by scholars and literati over the centuries.

Layout: Preserving Rice Paddies and Arranging Buildings Around Them

The new development is a homestay complex, combining multiple homestay brands. The first phase includes two distinct homestays serving different groups, sharing public spaces such as a book bar, outdoor swimming pool, and a restaurant.

Upon reviewing the broader planning strategy, the architect learned that rice paddies would be incorporated into future village development. Therefore, building in this area does not conflict with agricultural land use. However, the question arose: is this the best approach? Although constructing directly in the paddies would simplify building challenges, it would damage the agricultural landscape and diminish the project’s charm. Ultimately, architects, builders, and operators agreed that preserving the rice paddies as the focal point of the homestay was paramount.

The buildings are positioned around the rice paddies, creating dynamic spatial relationships and visual interactions reminiscent of the “see and be seen” concept found in traditional Chinese gardens. In this analogy, the rice paddies function like water surfaces in gardens, serving as both a focal point and a stage for human activities. After opening, the homestay hosted events such as harvest festivals and rice field yoga, reinforcing the rice paddies’ central role.

The guest rooms and reception are nestled at the base of the mountains on the west and south sides, offering excellent views while minimizing farmland impact. The original road was rerouted westwards, passing between the new buildings and the forested mountain behind, isolating the buildings and rice fields from traffic disturbances and facilitating secure management.

The book bar and outdoor swimming pool are clustered on the north side of the rice paddies, backed by a forest. The restaurant, uniquely situated within the rice field on the east side, is built underground to blend seamlessly into the landscape. A watchtower stands in the southeast corner of the core area, serving for high-altitude observation and forest fire prevention.

Guest Rooms: Tailored Design, Calm and Practical

The project required 25 guest rooms to meet operational needs. However, to protect the environment, construction was restricted to a limited area, posing a design challenge: maximizing comfortable accommodations within a confined footprint while keeping building height modest.

The guest rooms are divided into two zones, each representing a different homestay brand: Feifuji and Yuanbai. Feifuji occupies the site of the original homestead (demolished due to structural issues) and faces the valley and mountain gap, offering the best views. This building has three floors with 12 rooms. The entrance and second floors feature rear porches, ensuring all rooms overlook the rice paddies.

The basement level is partially above ground, designed by leveraging the site’s natural slope. The staggered cross-section arrangement positions the basement’s roof as an outdoor terrace for the entrance floor. Besides the balcony, a shallow water pool enhances comfort and outdoor enjoyment while adding visual interest. This staggered design visually divides the building, reducing the massing impact of the three floors.

An old tree to the south carries historical significance. The architect preserved this tree, building adjacent to it to create a symbiotic relationship. A wooden deck under the tree connects to the shallow water pool, forming a pleasant outdoor leisure space.

Yuanbai Homestay is mainly located at the mountain base south of the rice fields, consisting of three two-story buildings. Floor-to-ceiling glass faces the rice paddies, bringing the scenic beauty inside. The split layout ensures privacy for each room while creating a “family-like” atmosphere.

The guest rooms exhibit a simple and calm architectural style, avoiding overly sculptural or modern forms. Buildings feature double-pitched roofs with extended eaves, suited to Dianjiang’s rainy climate. Walls are constructed with innovative adobe materials, balancing low maintenance costs with a traditional residential appearance.

Book Bar and Swimming Pool: Interpreting Local Venue and Traditional Residences

Besides guest rooms and reception, several small buildings scattered throughout the site serve as public amenities and scenic highlights, contributing to the project’s overall atmosphere.

The book bar functions as both a library and water bar, located on the north side adjacent to the outdoor pool and opposite the Yuanbai homestay. It features a large roof inspired by the local traditional residential architecture, where roofs of wing rooms, kitchens, and pigsties merge to form a continuous, sweeping roofline with eaves near the ground.

The architect adapted this distinctive regional element into the book bar’s design. Its asymmetrical double-pitched roof has intentionally lowered eaves facing the rice paddies, creating a unique, calm, and extraordinary silhouette. This horizontal composition directs views toward the rice fields, guest rooms, and restaurant. Inside, visitors can immerse themselves in the surrounding scenery.

The outdoor swimming pool was renovated from an original fish pond, minimizing earthworks and enhancing landscape drama. Infinity pools are now standard in high-end homestays, and here the architect envisioned one set within the rice fields. As the agricultural landscape improves, the pool will blend even more seamlessly with the paddies, offering a romantic swimming experience surrounded by the scent and texture of rice plants.

Restaurant: Hidden in the Rice Fields, Welcoming the Sunrise

The existing small-scale restaurant will focus on specialty catering after the second phase’s completion of a larger facility. Initially, the architect planned a modest building on the site’s eastern mountain gap to serve as a scenic viewpoint, allowing guests to witness sunrises, seas of clouds, and panoramic views of the county town from a cliff edge.

The restaurant was built at the rice field’s edge and buried underground to minimize landscape disruption. It features a simple linear layout, a single-slope concrete roof, and floor-to-ceiling windows facing the cliff gap, maintaining transparency between inside and out. The roof employs reverse beams to keep the ceiling flat, avoiding conventional roofing methods. Instead, rice is grown on the roof using soilless cultivation, with crossbeams acting as water-retaining barriers. This rooftop rice field integrates the building into its surroundings while giving it a distinctive character.

A small bubble pool next to the restaurant was added per the owner’s request. Positioned at the cliff edge with stunning views, the pool and restaurant face east, making them perfect for welcoming sunrise. Evenings are illuminated by warm indoor lighting and candlelight on the outdoor deck, creating a romantic atmosphere.

Landscape: Respect for Nature, Simplicity, and Authenticity

The project site enjoys a unique setting: mountains on three sides, an open eastern side, and a central rice field encircled by forest creating a serene paradise. This is not an urban environment but a retreat for modern city dwellers seeking “poetry and distance.” Consequently, the landscape design emphasizes minimal urban intervention, embracing a rustic, rural character.

The rice paddies are fully preserved. The road originally between the village and paddies was relocated west of the new buildings, allowing for a direct connection between buildings and fields. Pedestrian pathways connect the structures, following original ridges and forest trails. Surfaces are intentionally uneven, composed mainly of stones and rootstocks, encouraging a leisurely pace and mindful walking.

Areas around the homestay and public buildings are mostly paved with hard materials, using local bluestone fragments or foundation stones salvaged from old site buildings. This choice reflects local character and evokes a subtle nostalgia.

At night, simple light bulbs mounted on low bamboo poles along the rice fields provide soft illumination. Each bulb is covered by a bamboo woven shade that diffuses the light gently. This modest yet thoughtful lighting design embodies the project’s desired atmosphere.

Conclusion: Blurring the Line Between Subject and Object—The Realm of Mountain People

Bagu Su Ji’s architectural design does not chase novelty but explores the relationship and interaction between architecture, nature, and people. The site’s original natural features are preserved as much as possible, while architecture is introduced as discrete points anchoring visual and behavioral experiences. Visitors wander amid buildings and landscape, gradually merging into the scenery, dissolving the boundary between subject and object. Time slows, and nature, architecture, and people become one—a realm echoing the ancient Chinese ideal of “mountain people.”

Since completion, Bagu Su Ji has quickly gained popularity for its exceptional natural environment, becoming a notable destination for tourists and a significant case study in rural revitalization through innovative use of idle assets. This success is credited to the collaborative efforts of government, property owners, operators, and designers, contributing valuable insights into local rural development under the “three changes reform policy.”
