Protecting traditional villages is essential for their sustainable development, and development itself is the true form of protection. We aim to set a model for renovating Miao village dwellings amidst evolving construction systems and building materials, striving for a balance between modern living needs and harmonious architectural style. Simultaneously, we seek to harness external resources to explore cultural heritage, revive craftsmanship, introduce industries, and build platforms for Longtang. This approach will help the village regain its intrinsic vitality, ensuring it thrives sustainably even after external support recedes, achieving genuine and lasting poverty alleviation.

The Dragon Pond, veiled in clouds and mist

Longtang Village, located in Leishan County, Qiandongnan, Guizhou, is renowned for its terraced tea forests cloaked in mist and its traditional wooden stilt houses perched along cliffs. The humble Miao people have lived here for generations, embracing a simple and natural way of life. Despite being listed among China’s traditional villages, Longtang has experienced decline due to a fragile industrial base and population loss.

In November 2013, China introduced the critical strategy of “targeted poverty alleviation,” which has since guided ongoing efforts nationwide. The Longtang Mountain House project in Miaozhai, Guizhou, marks Rongchuang’s inaugural participation in rural revitalization and poverty alleviation initiatives. Leveraging Line+’s extensive rural revitalization experience, Rongchuang China and the Youcheng Foundation of the State Council Poverty Alleviation Office jointly commissioned Line+ to deeply engage with Longtang and reimagine the village.

The project covers 2,400 square meters, including 1,650 square meters of new construction and 750 square meters of renovation. The new build features eight individual guest rooms, restaurants, cliffside theaters, infinity pools, and other public areas, alongside hiking trail development and partial landscape restoration. These efforts aim to invigorate village life and production, fostering sustainable growth in cultural tourism.

Addressing the evolving needs of traditional rural life

During their research in Longtang, the Line+ team encountered a widespread challenge in traditional villages: spontaneous renovations by villagers. Many have replaced traditional features with aluminum alloy doors and windows to better withstand the climate. Elevated storage areas originally meant for agricultural tools have been expanded using modern materials like cement and bricks to create living spaces and bathrooms. The village secretary noted, “With the new road, basic modern building materials have become easily accessible. Villagers are renovating their homes, but some experts say these changes are destructive.”

Life in Miao Village

The project seeks to blend traditional dwellings with modern living requirements, combining traditional styles with new industrial materials, and revitalizing traditional craftsmanship alongside emerging industries. This approach balances the pastoral ideal with practical development needs, all within a constrained budget—a significant design challenge. Line+ embraces these complexities, responding architecturally to the decline of this traditional Miao village.

Respecting history while embracing the future, Line+ demonstrates residential renovations within the protected area and introduces boutique homestays with contemporary and futuristic elements outside this zone. These designs mimic traditional stilt houses, creating a parallel between existing structures and new additions. The goal is to improve villagers’ quality of life while understanding the cultural context, enhancing accessibility, and revitalizing this secluded community to foster self-sufficiency.

Adaptive renovation: stock transformation

Through detailed study of traditional Miao stilt houses, the stock renovation approach addresses villagers’ lifestyles and needs at a cost comparable to spontaneous renovations. The design team hopes this model will inspire villagers to renovate their homes in ways that preserve traditional styles while preventing disorderly changes.

△ Stock transformation strategy

The design prioritizes balancing traditional architecture with modern demands while minimizing the visual impact of new materials. Renovations preserve the original building structure and facade, integrating essential modern amenities—such as kitchens, bathrooms, and tool storage—into elevated layers and sides of the existing structures. Some elevated areas remain open for daily needs like shelter, socializing, and parking. Sloped roofs maintain village style while providing ventilated, sheltered drying spaces. Solar panels are added to introduce green energy.

Growth and Dialogue: Incremental Additions

“Longtang Mountain House” follows the traditional stilt house typology, built along mountain ridges with staggered heights that preserve views and address terrain differences. Situated outside the protected scenic area yet maintaining visual connection, the project creates a dialogue between the village’s past and its future.

The guest rooms draw inspiration from traditional Miao stilt houses, elevated above the ground to ensure ventilation and moisture protection, with equipment concealed beneath. The structures appear suspended on the mountain slope, blending into the landscape when viewed up close or from a distance. Entrances are cleverly positioned where the building meets the mountain, creating a vertical spatial relationship with the terrain.
