Following the design concept of "Shanshui Hengqin, the Living Hall of the Grand Bay Area," this building will be progressively opened to the public before the end of the year, marking the third anniversary of the creation of the Hengqin Guangdong-Macao In-depth Cooperation Zone. By July 2025, the complex will be fully opened.Three arches in the twilight.

There are dozens of large projects under development, all of which are within 34 nautical miles from Hong Kong and within walking distance of Macau. With clusters of developments aimed at the prominent fields of culture, creativity, and knowledge, the 106-square-kilometer island is a recent addition to the populated area.Reflection on the facade.

The firm's winning proposal focused on embracing innovative design and concepts.View from the park. Image © Schran Image"The complex houses nine departments, but the requirements for each of them were independent and filled with contradictions,” explained Yunchao Xu, lead architect of Atelier Apeiron. "We approached it from the perspective of integrating nine independent buildings into a single complex, and we convinced the client to give each department relative independence in order to proceed with a comprehensive strategy that resolves conflicts and stimulates public energy," Apeiron added.South facade.

How to bring natural light into such enormous dimensions was another difficult aspect.Overall view. Image © Schran ImageThe foundations of the vast complex also offered a challenge because of the island's subtropical temperature and a naturally occurring silt layer that might lead to stability problems. In order to guarantee optimal strength throughout the construction, the business responded by designing a basement as an enclosed support compartment with anchor points.The roof garden and plaza. Image © Shengliang SuGateways of arts and cultureThe Hengqin Culture & Art Complex is situated between an open city park and existing residential buildings. Atelier Apeiron developed  a plan to build a dynamic complex that can support a multipurpose future. The firm advocated an architectural approach characterized by large-scale porosity as part of that concept, tailored to the high-density urban setting of the site's surroundings.Waterfront view. Image © Shengliang SuApeiron articulated an architectural language that blends Chinese and Western elements on the complex's bottom level by using the geometric concept of an inverted catenary to construct three beautiful arches of varying shapes. Every arch acts as a doorway to a distinct hall with its own personality and agenda. The firm added two diffuse reflectors that softly guide sunlight into the rooms and carved a skylight above the arches to create linkages with the rooftop gardens in order to bring natural light into the naturally dark areas.Three arches in the twilight.

Visitors can take in unhindered views of the nearby park during the day, and at night, the soft lighting from the translucent arched hallways will serve as a stage backdrop for a range of public activities that will take place in the park.Sunken plaza under the cantilever. Image © Schran Image"Arches have been embraced as a critical form of architecture since the beginning of time and are prevalent in both eastern and western culture," explained Yunchao Xu. "To create strong structures with available materials, arches have been used to convert shear force in a horizontal direction into vertical force, ensuring that all points of the structure carry a shared load."Sunken plaza under the cantilever.

In order to accommodate building services and equipment, little areas have also been incorporated inside the arch joints.Library. Image © Schran ImageA diversity of atmospheresYunchao Xu/Atelier Apeiron worked to desegregate the experience in order to create a truly communal sense of being. The enormous complex was designed to house nine distinct functions: a library, an archives center, a concert hall, a cultural center, an art gallery, a science museum, a women's and children's activity center, an elderly activity center, and a youth activity center. Each arch leads into a distinct area, which includes an Exhibition Hall, a Performance Hall, and a Knowledge Hall. The building is designed as three urban living spaces.Library with book mountain.

With its vertical village of crystal book blocks, the Knowledge Hall will elevate the idea of traditional libraries to a new level and serve as a hub for public urban activity.With a large open stage and a black box theater for dance, music, theater, and opera shows, the nearby Performance Hall functions as a cultural performing arts center. Book mountain.

Image © Schran Image"The modular design of the complex ensures that each of the nine pavilions has its own distinct spaces, and the three large halls follow that same rationale," said Yunchao Xu. "Our vision is for the Hengqin Culture & Art Complex to be a vibrant, three-dimensional vertical city that will host millions of tourists each year, as well as a growing community of local residents, while seamlessly connecting with its surrounding environment."View towards the park.

To guarantee the best sightlines from every platform, the team carried out several research when constructing the gardens.View towards the park.

A 24-meter platform that doubles as a children's theme park has restaurants, museums, family cafes, sand pits, and large play areas. Another platform offers a communal garden at a distance of 30 meters, along with cafeterias and staff canteens for workers to relax and take in their surroundings. View towards the park.
