Mandarin Oriental Hotel Group has completed the topping out of its latest development in Hong Kong, One Causeway Bay. The building is the city's newest premium waterfront commercial development, situated in the rapidly evolving Causeway Bay neighborhood.

The development occupies "Lot No. 1," the first piece of land acquired in Hong Kong by James Matheson in 1841, which inspired the name "One Causeway Bay." The site was previously home to the famed Excelsior Hotel from 1973 to 2019, and remains under the ownership of Mandarin Oriental Hotel Group.

One Causeway Bay is a Grade A premium commercial development, designed by Kohn Pederson Fox and Ronland Lu & Partners. Inspired by its unique harbourfront location, the building's facade reflects the movement of waves in Victoria Harbour with interlocking and undulating glass panes. The building has been designed with a focus on occupant wellbeing and sustainability, aiming to deliver a cutting-edge workplace with advanced property technology and facilities for tenants. Features include state-of-the-art air purification systems and a green rooftop terrace.

Laurent Kleitman, Group Chief Executive of Mandarin Oriental Hotel Group, commented: "One Causeway Bay represents a reimagination of the workplace in Hong Kong. We are bringing our globally renowned reputation for craftsmanship, elegance and exceptional service, combined with modernity and innovation, to the office market in Hong Kong to create a truly unique space. Sustainability is at the core of the redevelopment, and we are delighted with the certifications already received."

Upon completion, One Causeway Bay will be a mixed-use tower, offering 500,000 sq. ft. of premium Grade A office space across 24 floors, and 55,000 sq. ft. of retail space over 5 floors, including a rooftop bar and restaurant. The building will be managed by Hongkong Land, a major listed property investment, management and development group.

Main contractor Gammon is overseeing the construction, using advanced materials and techniques to ensure a world-class design and finish. Gammon is dedicated to pioneering sustainable construction practices that contribute to a greener and healthier future.

One Causeway Bay has been designed to the highest sustainability standards, focused on enhancing tenant wellness, increasing operational efficiency and reducing environmental impact. Sustainable materials such as green concrete, green rebar, FSC-certified timber and recycled materials were used throughout the building. Upon completion, the building will feature AI-optimized chiller plant control and energy-saving LED lighting systems.

The building has already achieved provisional Platinum rating from BEAM Plus, Platinum pre-certification from LEED, pre-certification from WELL, and a Platinum rating from WiredScore. It is also targeting a Platinum rating from SmartScore certification.

A show suite will be launched in August to showcase the building's design. The project is expected to open in Q2 2025.
