> QUERY: "Steps to restore ancestral home in Shantou into a Clan Shrine/Museum; compliance and preservation focus."
1. REGULATORY SCAN (THE MUNDANE)
Agent performed a deep-dive on the Law of the PRC on Protection of Cultural Relics and Shantou Urban Planning Regulations.
Constraint Identified: Under Article 21 (Cultural Relics Law), the "Principle of Not Changing the Original State" is mandatory. Changing the use code from Private Residential to Public Assembly (Museum) triggers strict GB 50016-2014 (Fire Code) requirements.
The Conflict: Traditional "Si Dian Jin" (Four Points of Gold) layouts utilize extensive timber (Chinese Fir) which fails modern 2-hour fire separation ratings required for public museums. Sprinklers would damage the intricate wood carvings and lacquer.
The Agentic Fix: Apply for a "Performance-Based Fire Design" (Special Expert Review). Instead of wet sprinklers, specify a high-pressure Water Mist System (doesn't soak the wood) and apply clear Intumescent Varnish to all structural timber.
2. PHYSICAL & ENVIRONMENTAL
> STRUCTURAL HEALTH: Teochew "Shell-lime" (SanheTu) walls likely suffer from capillary rising damp. Restoration requires "desalination" of granite base stones before repointing. > BIOLOGICAL HAZARD: High risk of Formosan Subterranean Termites. The "Agentic Fix" includes a non-repellent soil barrier treatment (Fipronil) around the perimeter trench before any wood restoration begins.
