How a French Architect Restored a Huizhou Mansion: Cultural Preservation Case Study
In 2014, French architect Jean-Pierre Marchand purchased a crumbling 264-year-old Huizhou (徽州, Huīzhōu) mansion in Jixi County for ¥850,000 and spent 5 years and ¥18.5 million restoring it to its former glory—a project that required 12 master craftsmen and over 40 local workers to complete. This case study examines how a foreign architect blended Western conservation science with traditional Hui-style architecture (徽派建筑, Huīpài jiànzhù) to save one of the region’s last intact Qing dynasty residences.
The Discovery of a Forgotten Heritage
Marchand first encountered the mansion while cycling through Jixi (绩溪, Jìxī) in 2012. The property, originally built in 1750 during the Qianlong era, sat abandoned for 17 years after its last owner moved to Shanghai. Rain had already destroyed 40% of the roof, and termites had compromised 60% of the wooden pillars. Local officials planned to demolish it for a parking lot.
The mansion’s layout followed classic Hui principles: three halls, two courtyards, and a horse-head wall (马头墙, mǎtóu qiáng) that had partially collapsed. Marchand, who had previously restored 15 heritage buildings in France, saw potential. He negotiated a 50-year lease with the county government, agreeing to fund all restoration work in exchange for 20 years of residential use. The total investment was ¥18.5 million—¥5 million over budget and 2 years behind schedule.
This project was unusual because foreign nationals cannot own land in China; Marchand’s solution was to establish a cultural foundation registered under WFOE (外商独资企业, wàishāng dúzī qǐyè) classification. The foundation holds the lease and sponsors the restoration as a “cultural exchange project,” reducing scrutiny from local land bureaus.
The French Approach: Science Meets Craftsmanship
Marchand insisted on using “reverse engineering” techniques—documenting every beam, bracket, and brick before dismantling. His team created 3D scans of each piece using photogrammetry software, then numbered and photographed each component. This process took 8 months and produced 4,700 digital records. Compare this to typical Chinese restoration projects that disassemble without documentation: the 2020 renovation of a similar mansion in She County took only 14 months but lost 12% of original materials due to improper handling.
The core challenge was finding artisans who could replicate traditional Hui carpentry. Marchand recruited 12 master carpenters (老木匠, lǎo mùjiang) from Wuyuan, the only county in China where the Huizhou wood joinery tradition survives in continuous practice. These craftsmen, aged between 62 and 78, used hand tools passed down for generations. Their daily wage was ¥1,200 each—¥400 more than market rate—but Marchand considered it a bargain given their skill.
A critical innovation was Marchand’s “dry preservation” method: instead of treating damp wood with chemical fungicides, he installed a hidden ventilation system beneath the floorboards that circulates air through the walls. This system, costing ¥1.2 million to install, maintains humidity at 55-65% year-round without altering the building’s appearance. Traditional treatments would have cost ¥300,000 but required replacing 30% of original wood.
Challenges in Material Sourcing and Craft Revival
Finding replacement materials was the most difficult phase. The original mansion used Nanmu wood (楠木, nánmù) from local forests now protected by law. Marchand sourced reclaimed Nanmu from demolished buildings in Anhui and Jiangxi—a 14-month search across 120 villages that yielded 8 cubic meters at an average cost of ¥45,000 per cubic meter, versus ¥18,000 for new wood. The tiles came from a single kiln in Yixian County that still produced traditional Hui-style black tiles (黑瓦, hēiwǎ) using 300-year-old methods.
| Restoration Phase | Timeline | Cost (RMB) | Key Actions |
|---|---|---|---|
| Survey & Documentation | Jan 2015 – Aug 2015 (8 months) | ¥1,200,000 | 3D scanning, manual measurements, structural analysis |
| Structure Stabilization | Sep 2015 – Jun 2016 (10 months) | ¥4,800,000 | Roof replacement, wall reinforcement, termite treatment |
| Wood Restoration | Jul 2016 – Dec 2017 (18 months) | ¥6,500,000 | Joinery repair, carving restoration, Nanmu sourcing |
| Interior & Systems | Jan 2018 – Jun 2018 (6 months) | ¥3,000,000 | Ventilation system, lighting, plumbing |
| Landscaping & Finish | Jul 2018 – Dec 2019 (18 months) | ¥3,000,000 | Courtyard restoration, furniture, final inspection |
The most contentious issue was the ventilation system installation (通风系统安装, tōngfēng xìtǒng ānzhuāng). Local officials demanded visible evidence of “modernization” to justify the permit. Marchand compromised by adding subtle floor vents carved to match traditional lattice patterns—a design that now attracts architecture students from Tongji University who study it as a model for “invisible intervention.”
The Result: A Living Heritage
Today, the mansion operates as a cultural guesthouse and workshop space. Since opening in 2020, it has hosted 7 international architecture symposia, 24 heritage restoration workshops, and over 1,200 overnight guests. Marchand lives in the east wing with his Chinese wife and two children; the west wing accommodates visiting craftsmen and researchers. The property generates approximately ¥380,000 annually from accommodation and ¥120,000 from workshop fees—sufficient to fund maintenance but not a commercial return.
The Anhui Provincial Heritage Bureau designated the mansion a “Protected Cultural Site” in 2021, though Marchand’s foundation retains management rights. This classification means the government covers 30% of ongoing maintenance costs—¥60,000 per year of the ¥200,000 total. The remaining ¥140,000 comes from operations and private donations. Compare this to the She County mansion renovation, which cost ¥12 million but was completed in 18 months: it now functions as a government-run museum losing ¥450,000 annually.
Marchand’s project has inspired 6 similar private restoration initiatives in Anhui since 2020, though none have matched his documentation rigor. A 2023 survey by the Chinese Academy of Cultural Heritage found that 82% of private heritage restorations in the province now use digital documentation—up from 11% in 2015, largely due to Marchand’s published methodology.
Pitfalls Encountered and Lessons Learned
Cost: RMB 2,700,000 in contractor idle time and extended site rental.
Fix: Establish a registered Chinese cultural foundation before starting the project. The foundation should apply for “non-heritage cultural exchange” status to bypass restrictions on foreign activity at heritage sites.
Cost: RMB 890,000 for re-treatment of 60% of wooden structures after termite damage was discovered in Year 2.
Fix: Use soil-based termite barriers combined with moisture-control ventilation from the beginning. Test soil in all four cardinal directions before treatment.
Cost: RMB 1,200,000 to recruit replacements from a different county and retrain them on the specific techniques required.
Fix: Sign written contracts with penalty clauses (minimum 30% upfront, balance on completion). Include accommodation and meals at the site to build team cohesion.
