"Trinity" is one of the key design principles of this project.

It implies the symbiosis of three main components – Office, Hotel and SOHO apartments. Although these buildings can be operated individually but while they function together, a powerful urban synergy is created from these separate entities.

Total GFA is 246,067 sq.m with a plot ratio of 12.6. It comprises of three 165.8m tall building, a 39 storey office tower, a 38 storey Hilton hotel and a 43 storey SOHO apartment. The crystalline building form signifies its status as the landmark in the city of Chengdu, with its modern and geometrical expression in curtain wall, has given the project a pure and classic appearance.

  • This  440-room 5-star business and resort hotel with a 2800 sqm banquet area exploits fully its sea view potential.

    There are two lots on the site: Lot A is for hotel and support facilities while Lot B for offices with entertainment podium. Facing a shoreline park the twin towers’ “V” site formation flanking a 50m wide green belt allows all the rooms’ 30 °angled bay windows to enjoy sea view without looking into one another and without completely blocking other inland buildings towards the sea.

    The intricate stepped facade treatments allude to seashell forms while the sail-like roof membranes establish a nautical presence and dramatic skyline seen both day and night.

  • Atkins’ architecture and urban design studio was selected by the developer, Huarong Real Estate Ltd Co through a design competition, as having provided an eye-catching and modern design which specifically responds to the site, the environment, and Huarong’s design aspirations of creating a landmark tower. This mixed-use development contains accommodation for a 5-star hotel, international grade-A offices and top brand retail facilities. It will be one of the first buildings to be built as part of the large masterplan of the new special economic zone of Hengqin Island District. This development benefits from a prime location facing the waterfront only a few hundred meters from the world-famous Cotai strip in Macau.

    The organic towers of this project are carefully arranged to provide hotel guests and office users with stunning views of significant landmarks in Macau, while respecting the development potential and view corridors of adjacent sites. The building orientation also protects its main entrances from wind, while the façade consisted of louvers in wavy forms which shade unwanted glare and accentuate the concept of a rippling water surface.

  • Named “Window of Canton”, this project defines the southern gateway to Guangzhou, the first Chinese city that pioneered trading with the west centuries ago. Moreover, the multi-tower masterplan development can be read as “001” from the south and “100” from the north, both being auspicious numbers. The concept uses only a 25m deep slab, thus allowing for daylighting and northsouth ventilation and views of both the famous Pearl River and the CBD skylight for all office units. Moreover, the use of solar shades on the roof, east and west elevations optimizes the energy conservation strategy. Lifting the “window” off the ground not only lightens the mass of this 178m-long building but also opens up uncluttered vistas to the river from future development to the north. The top floor unit will boast a 178m long panorama of the Riverbank Park and marina occupying a shipyard converted into a yacht club.

  • Located at Tianjin TEDA Modern Service District, H2 low carbon building was conceived as a demonstration project and research platform for green building technologies. The top floor and roof garden of the 9 storey building is designated as a showcase for low carbon building technologies, while the remaining floors for the slab tower are office spaces. The 2 storey podium will be occupied by retail shops, bank, F&B outlets and main lobby. Parking lots, MEP equipment and auxiliary facilities are located in the 2 storey basement. H2 low carbon building has been accredited the first office building in the world with 4 green certification; China 3 Stars, CASBEE, BREEAM and LEED.
