83 King Lam Street - HKIA Award of Hong Kong - Office Building

83 King Lam Street won the HKIA Award of Hong kong Office Building category 2025. A great recognition for COLLECTIVE, who is the Design Architect for the Architecture and Interiors of the podium, including the public steps, landscape design, auditorium design, co-working space design and lobby design; COLLECTIVE is also responsible for the interiors of the twin towers.

COLLECTIVE partnered with Rocco Design Architects, who is the Design Architect of the twin towers and the Executive Architect of the project.

83 King Lam Street consists of a major podium for a set of new commercial office twin towers situated in the old industrial heartland of Lai Chi Kok along King Lam Street, redefining the new “Privately - Owned - Public Spaces”. The building site is nestled between King Lam Street on the south and the rising lush green hillside of Kam Shan Country Park to the north. As one transitions from the busy Lai Chi Kok’s subway exits and main roads towards the site; the area begins to have the feel of a quieter and calmer cul-de-sac, where traffic is reduced, and the green mountain backdrop starts to be visible.

A PIXELATED LANDSCAPE

Forming the centerpiece of the podium is a cascading landscape of steps – the ‘feature steps’ – which rhythmically winds its way up and down, left and right, connecting each level of the separated podium. Its parametric surface is expressed as a series of pixelated steps with varying heights, thereby creating a landscape of stairs, seats, and planters. At the top of the podium, the pixelated steps conglomerate into another landscape of tree planters and green walls, blending into the site’s rising green back-drop. In addition to effectively linking the base of the two towers, this fabricated landscape, and its curated greenery is meant to be an intentional extension of the natural green mountainside into the city’s urban fabric.

AUDITORIUM

Inserted below the Feature Steps are two connected interior auditorium spaces – the upper and lower auditorium. The two spaces may be used as a single event space or partitioned to be used separately. The seats of the upper auditorium can also be retracted, transforming the room into a multipurpose open plan, thereby offering an event space as an additional amenity to office tenants. Architecturally, the auditorium space is distinguished by a unique stepped ceiling of varying heights, geometrically reflecting the parametric and pixelated nature of the exterior feature steps above.
