rock-like skylights pop up on blue insight cave’s green rooftop by 3andwich

Blue Insight Cave Space resembles reefs and sea caves

3andwich Design / He Wei Studio architecture office shapes Blue Insight Cave Space, situated along Donghai No.1 Road, Ningde City, Fujian Province, China. The design focuses on environmental harmony, emphasizing low-carbon and energy-efficient solutions. The building, partially buried underground, minimizes energy consumption by maintaining a stable indoor temperature and reducing cooling needs in summer. Inspired by the reefs and sea caves around the site, the design team created an irregular exterior shape, incorporating structural and functional openings, such as doors and windows, to form a dynamic interplay of geometric cuts and angles. The building’s form subtly evokes a reef-like abstraction. The roughened concrete gives the structure a rock-like texture, further enhancing its connection to nature.

3andwich Design engages in an interplay of geometric forms

The roof features uniquely shaped ventilation and lighting openings, designed to mimic marine creatures in the form of flat circles, triangles, and long tubes. These elements are freely arranged on the rooftop’s grassland, offering photo opportunities for visitors while ensuring indoor ventilation and light. The main entrance, located on the west side of the roof, features a semi-circular shape that extends from the underground, with a descending passage leading inside. The designers at 3andwich Design / He Wei Studio shaped the interior out of interconnected ‘cave’ spaces, creating an organic and dramatic atmosphere. The layout includes three primary areas: a lobby, a main space, and a logistics area. The main space, with its salon and gallery, is positioned to face the sea, offering striking views. This versatile space hosts exhibitions, small gatherings, and provides catering services.
