We propose a palimpsest-like restoration where the patina of time remains legible, and new interventions—expressed through contrasting yet respectful materials—create layered narratives within the ancient space.
IN-SCOPE WORKS
A. Heritage Conservation
1. Structural Stabilization:
- Repair stone walls with cracks >2mm;
- Consolidate eroded mortar joints in designated zones (A, B, C).
2. Dougong Preservation:Only Grade B/C interventions allowed.
B. New Interventions
1. Steel Platforms:
- Install 3 circular viewing platforms (max. 120㎡ total);
- Embed 5 AR kiosks showing castle history reconstructions.
2. Flow Optimization:
- New pedestrian route via platforms (reduce detours by 40%).
C. Cultural Activation
- Convert stable ruin into pop-up gallery (200㎡), retaining original feeding troughs.
I. TECHNICAL SPECIFICATIONS
SECTION 01 00 00: GENERAL REQUIREMENTS
Heritage Conservation Principles
Minimal Intervention:Demolition limited to structurally hazardous elements; original dougong (timber bracketing) to be retained ≥95%.
Reversibility: All new steel platforms shall use detachable anchors (Type M16 stainless steel bolts) without core-drilling historic stone.
Authenticity: Existing wall patina, cracks, and weathering traces preserved; cleaning via low-pressure helium blasting (≤0.5 MPa).
Steel Platform Assembly
Structural Frame:Circular platforms – Cantilever trusses (max. span 8m); Square platforms – Modular grid units (1.2m×1.2m).
Connection Details:
50mm gap between steel and stone walls with silicone sealant (RAL 7013);
Titanium-zinc flashing at interfaces to block capillary moisture.
