The project of Hainan Smart Ecological New City Digital City Hall, themed “Garden & Courtyard”, is a multi-functional building available for exhibition, creative industries and commercial offices. The design, starting from climatic strategies for subtropical zones, has introduced terraced fields, a series of interconnected courtyards at various altitudes, outdoor atriums and cooling alleys into the build-ing. Taking the abstract prototype of Eastern gardens and courtyards as reference, these spaces are integrated into the multi-functional city hall to from a multi-dimensional public space with gardens and courtyards, where people enjoy various scenes with changing viewpoints through the winding paths.

This project is located in the southwest corner of the Tencent Eco Village Park of “Hainan Eco-Smart New City”, Chengmai County, Hainan Province. Next to the main entrance of the Park, the building is arranged with courtyards and platforms. Each floor has an outdoor platform and faces to the southwestern landscape. The core is designed in combination with the entrance hall, the small halls and the corridors. Here are also arranged elevators, toilets and some equipment rooms. The main spaces of each floor can be accessed through the core, and each space has an approach that leads directly to the outdoor platform. 

The first floor is mainly for the exhibition, multi-function hall, café and tearoom. The north side is used as the main entrance for reception. Through the courtyard, visitors can get into the main hall. Combined with the landscape terrace on the southwest, the first and second floors cover with earth, in order to reduce energy consumption while enhancing ventilation and lighting.

The second to fourth floors are designed as office space, which can be accessed through the elevator in the lobby. It is also possible to walk directly up to the shared platform on the second floor, and then enter each office.

In each floor there are a roof platform. The upper and lower platform are connected by outdoor stairs, which lead to the outdoor landscape terrace. In the outdoor shared hall in the east, there is also a vertical stair for urgent evacuation.
