Location: High-end Residential Apartment, Hong Kong
Completion Date: June 20, 2024
Key Features:

· Premium imported North American walnut treads with oiled finish

· Robust 150×150×6mm carbon steel stringers with matte black powder coating

· 8mm carbon steel tread supports for maximum stability

· Frameless 6mm tempered glass guardrails for unobstructed views

Design Philosophy

This staircase was designed for a luxury Hong Kong residence where material authenticity and structural purity were paramount. The warm walnut treads float against industrial-grade steel elements, creating a perfect balance between organic warmth and urban sophistication.

Technical Execution

1. Material Selection & Fabrication

· AAA-grade walnut (minimum 80-year growth rings) selected for color consistency

· Precision-machined steel components with 0.3mm fabrication tolerance

· Anti-vibration tread supports prevent creaking

2. Structural Innovations

· 150mm square tubular stringers provide 6kN/mm² load capacity

· 8mm steel tread brackets welded with aerospace-grade techniques

· Hidden fastening system maintains clean lines

3. Glass & Finish Details

· Low-iron glass panels (6mm) with nearly invisible standoff fittings

· Hand-rubbed walnut oil finish (7-coat process)

· Custom steel-to-glass clamps anodized to match hardware

Why This Project Stands Out

· Material Contrast: The rich walnut against blackened steel creates dramatic visual tension

· Spatial Efficiency: Compact footprint (1.2m width) maximizes tight Hong Kong floorplan

· Acoustic Performance: Isolation pads eliminate metal-on-metal contact sounds

Client Testimonial
"The staircase feels simultaneously solid and lightweight - exactly the architectural statement we wanted. The walnut's depth changes beautifully with the light throughout the day."
