The West Kowloon landmark project in Hong Kong, designed by Zaha Hadid Architects, is rapidly taking shape. This futuristic building, regarded as a transformative departure from traditional office typologies in Hong Kong, reshapes the city skyline with its highly sculptural, flowing form.

As one of the key curtain wall glass suppliers for this landmark project—once the most valuable development site in Hong Kong—NorthGlass, with its industry-leading “Super Flat & Spotless” glass manufacturing capabilities and high-precision curved tempering technology, has delivered approximately 60,000 square meters of high-performance architectural glass solutions for this world-class building.

The overall design is inspired by a series of interconnected “petals,” each unit featuring different orientations, heights, and curvatures, collectively forming a dynamic architectural expression. The tower tapers inward at both the upper and lower sections, reducing its perceived mass while creating more open public urban spaces and improving natural ventilation efficiency. Vertical shading fins extend from the façade up to the roof, forming a distinctive “halo” effect that enhances the building’s recognizability along the Victoria Harbour skyline.

Such a free-form and complex architectural language places extremely high demands on the curtain wall glass system. The project uses approximately 14,000 glass panels, with nearly every piece differing in size, shape, and curvature. Among them, curved glass accounts for around 25,000 square meters, with the largest single panel reaching 5 meters. A large proportion of 3m × 3m oversized tempered glass panels are used, imposing stringent requirements on flatness, optical quality, and batch consistency. The irregular curved glass is concentrated in key visual zones such as the upper and outward-bulging middle sections of the building, involving multiple radii, bidirectional bends, and complex curvature control, all of which present significant manufacturing challenges.

To meet these requirements, NorthGlass fully leveraged its independently developed tempering equipment and process technologies. Using its top-tier proprietary tempering furnace systems, combined with intelligent out-of-furnace temperature control, super-symmetric heating technology, and gapless convection heating, the glass is heated more uniformly, significantly improving flatness and optical quality for oversized panels, ensuring a clear, true, and continuous reflective façade effect.

For the large volume of curved and irregular glass, NorthGlass adopted its self-developed automatic arc-forming tempering furnace. With a precise thermal field control system and automated forming technology, it achieves high-precision shaping for varying radii, bidirectional bends, and complex curved surfaces, ensuring each glass panel precisely matches architectural design requirements.

At the same time, NorthGlass continuously optimizes its tempering processes, achieving ongoing breakthroughs in complex surface forming control, reduction of roller wave distortion, and improvement of optical quality—allowing the building’s smooth and elegant curved form to be faithfully realized.

In terms of glazing configuration, the project adopts a silver-grey laminated insulated glass system combined with NorthGlass solar control coating and double-silver Low-E glass. This achieves a highly transparent visual effect while significantly improving building energy efficiency.

The combination of high-performance glass and complex curved structures not only gives the building a futuristic appearance but also demonstrates NorthGlass’s comprehensive technical strength in the field of high-end architectural glass.

As one of Zaha Hadid Architects’ landmark works in Hong Kong, the project represents a future direction for office architecture and embodies green and low-carbon design principles. It has achieved a BREEAM “Excellent” rating and received the highest pre-certification levels for LEED, WELL, and HK BEAM Plus. High-performance curtain wall systems, vertical shading elements, and photovoltaic components integrated into the roof and façade collectively reduce energy consumption and decrease reliance on the urban power grid.

From the OPPO Global Headquarters in Shenzhen to this Hong Kong West Kowloon landmark, NorthGlass continues to participate in the construction of world-class complex architectural projects. Facing curtain wall systems where “no two panels are the same,” NorthGlass transforms architects’ most ambitious curved concepts into tangible urban landmarks through independently developed equipment technologies, lean manufacturing capabilities, and strict quality management. Looking ahead, NorthGlass will continue to push the boundaries of architectural glass innovation, contributing more outstanding works from China to skylines around the world.
