First presented by ZHA in 2007, The Opus was conceived as two separate towers that coalesce into a singular architectural whole, taking the form of a precise glass cube. At its centre, the cube is dramatically “eroded” to create an eight-storey free-form void, conceived as an important architectural volume in its own right.

The two halves of the building are linked at ground level by a four-storey atrium and connected 71 metres above ground by an asymmetric bridge. The intervention creates a strong contrast between the cube’s precise orthogonal geometry and the fluidity of its central opening.

Advanced Glass Façade Engineering

The façade is fundamental to The Opus’s architectural expression. The cube’s double-glazed insulating façades incorporate a UV coating and mirrored frit pattern designed to reduce solar gain. Applied across the building, the dotted frit also reinforces the clarity of the cube while creating constantly changing reflections and transparency.

The central void presents a substantially more complex glazing challenge. Its approximately 6,000 m² façade comprises around 4,300 individual glass units, incorporating flat, single-curved and double-curved elements.

The high-efficiency glazing units consist of 8 mm Low-E glass, coated on the inside, a 16 mm cavity, and two layers of 6 mm clear glass laminated with 1.52 mm PVB resin. Digital 3D modelling was used to develop the complex curved façade and identify specific zones requiring tempered glass.

The result is a façade system in which glass transitions from conventional planar geometry to highly customised curved components, allowing the central void to achieve its fluid appearance while maintaining high-performance insulating characteristics.

A Dynamic Façade by Day and Night

The building changes significantly according to lighting conditions. During the day, the cube’s reflective façade captures the sky, sunlight and surrounding Dubai skyline. After dark, the central void becomes an illuminated architectural surface through a dynamic lighting installation incorporating individually controllable LEDs within each glass panel.

The Opus is home to the ME Dubai hotel, operated by Meliá Hotels International, alongside residences, offices, restaurants and hospitality spaces. The hotel represents an unusually complete Zaha Hadid design, with the practice responsible not only for the architecture but also for extensive elements of the interiors.

The project has received extensive international recognition. In 2022, The Opus received the MUSE Hotel Award in the Architecture Design – Hotels & Resorts category. The award programme aims to recognise projects that raise standards across the hotel, hospitality and tourism industries.

The building has also received the 2021 Architizer A+ Awards Jury Winner, 2021 INDEX Awards Hotel Design of the Year, 2021 Prix Versailles World Awards Winner, and the 2019 CTBUH Award of Excellence for Best Tall Building under 100m.

Newly released technical details now reveal the extraordinary façade engineering and manufacturing processes behind the building’s iconic appearance, positioning the project as a benchmark for next-generation curved architectural glass.

The theatre’s undulating envelope was inspired by a prose-poem by Aboriginal Elder and artist Lilla Watson, referencing fish moving beneath the surface of the Brisbane River. Rather than applying symbolism superficially, the architects translated this movement directly into the geometry of the façade itself. According to Michael Rayner, Director of Blight Rayner Architecture, the intent was to create a transparent “public theatre” where activity inside the foyer would become visually layered and animated from the surrounding streetscape.

Delivering this effect required one of the most complex curved glazing applications seen in a contemporary performing arts project. The façade incorporates large-format, double-curved insulated laminated tempered glass manufactured by NorthGlass. Individual panels reach approximately 7 metres in height and achieve a minimum bending radius of just 1 metre, an extremely tight curvature for insulated laminated units of this scale.

What makes the system particularly challenging is the continuous transition between concave and convex geometries across the façade surface. Unlike standard cylindrical bending, these panels required highly controlled free-form curvature to maintain the fluid “water ripple” effect envisioned by the architects. Any inconsistency in curvature alignment, roller-wave distortion, or reflected image quality would become immediately visible across the transparent envelope.

To achieve the required optical performance, NorthGlass reportedly developed a new generation of bending equipment specifically for the project and upgraded multiple stages of its production line. Significant advancements were made in roller-wave control, anisotropy reduction, and surface distortion management, critical factors for large-scale curved façade glass where reflected cityscapes and daylight conditions constantly expose imperfections.

The insulated laminated tempered units also needed to satisfy demanding structural and environmental performance criteria, balancing curvature with wind-load resistance, thermal insulation, safety compliance, and long-span stability. Maintaining dimensional accuracy across panels approaching semi-circular curvature represented a major manufacturing and quality-control challenge.

Beyond its visual impact, the project reflects a broader evolution within façade engineering: the transition from planar curtain walls toward highly expressive free-form envelopes that demand integration between digital modelling, precision fabrication, and advanced tempering technologies.
