A living wall is the highest-impact greenery for a corporate space — get clear on system, cost and upkeep first.

Living vs artificial

Living: strongest for air purification, humidity, acoustics and life — needs irrigation, lighting, care. Artificial: zero maintenance, great for windowless corridors or logo walls — no ecological function.

Irrigation

Recirculating (closed-loop) for large walls; direct-feed from plumbing; manual for small walls.

Lighting (essential indoors)

Full-spectrum white LEDs, ideally 12–15 hours/day (around 14) with even coverage.

Cost (indicative — get a site quote)

Roughly US$200+ per sq ft (about HK$1,500+/sq ft). WaaS subscription: reception (~8 m²) ~US$15k–22k install; open-plan (~16 m²) ~US$24k–38k. Always price by on-site survey.
