K11 Atelier King’s Road is an urban office redevelopment project in North Point on Hong Kong Island. With a total GFA of 45,300 m2, the building features 22 office floors with sky garden, exhibition space and F&B outlets. Integrating over 70 sustainability features, the building not only creates a sustainable and pleasant workplace, but also brings green and healthy to the neighbourhood.
Arup was appointed by New World Development to provide engineering services in building sustainability, MEP and façade engineering services on the building, which is the second K11-branded office we have worked on in Hong Kong following our work at K11 Atelier Victoria Dockside.

Distinctive envelope
This project is situated in the typical Hong Kong urban landscape with extensive greenery wrapping the podium. Together with the roof, the total greenery covers an area of 6,700m2, which is equivalent to 2.2 times the total site area. It contributes to the carbon sequestration of 4 tonnes of CO2 each year and reduces urban heat island effect in the high-density neighborhood.
The podium is greatly set back on all façades to enhance the natural air ventilation at pedestrian level
Its ‘floating green box’ podium is greatly set back on all façades at pedestrian level, up to 12.8m, to enhance the accessibility and comfort at street level. The building envelope adopts a cubic recession and projection design to further introduce greenery and visually enrich the view at low-zone floors.
Pushing the boundary
We equipped the building with Hong Kong’s first and Asia’s largest commercial hybrid solar photovoltaic and thermal (PVT) installation on the rooftop with an area of 220m2. A total of 138 PVT panels co-generate electricity and hot water for the lift lobby lighting and showers on typical floors. The system has a higher energy efficiency than conventional photovoltaic systems, with an annual renewable energy generation estimated to be 77,000 kWh, accounting for 1.3% of the total building energy use. A 3kW wind turbine is also installed for powering-up the landscape lighting.
Pleasing environment
On the rooftop, there is a microclimate-controlled sky garden informed by CFD and thermal comfort design techniques. Microclimate modifiers of 2m height are designed at specific locations to shield the activity space from the winter prevailing wind to enhance its usability.
An area of 70m2 urban farming planter boxes allow the occupants to enjoy gardening, while the freshly grown vegetables and fruits are served in the building’s F&B outlets. A 170m-long biophilic jogging path is also featured to encourage physical activities.
WELL-designed interior
Efforts were put into designing the office space to achieve the highest wellness standard, covering air quality, visual comfort and thermal comfort.
The high performance low-e glazing provides solar control and good daylight availability, while the LED lighting system is linked to the daylight sensors for energy saving and circadian lighting. The use of air handling unit and supply diffusers ensure the best air quality and thermal comfort level in terms of pollutants level, temperature distribution and air movement velocity. As the world’s first building to have achieved the WELL Building Standard (core and shell) pre-certification, this ideal workplace environment is expected to increase productivity of building users.
Comprehensive sustainability
With dozens of other key sustainability and wellness features designed by Arup, from electric glare control to olfactory comfort design at lavatories and pantries, the project achieves over 30% energy savings against the ASHRAE Standard. It is the first building in Hong Kong to achieve Final Platinum levels of WELL and LEED certifications.
