Open Architecture Designs A 50-Meter Tall Concrete Sun Tower in China

Beijing-based architecture studio- Open Architecture- has started the construction of this 50-meter high tower in China that appears like a huge sundial. Located in Yantai in the northeast of China facing the yellow sea, the "Sun Tower" stands as a landmark in the city. Once complete, the building will accommodate a cultural facility, a spiralling exhibition space, a semi-outdoor theatre, an observation deck and a beautiful library in the sky. The firm used white concrete to design the structure, which is informed by watchtowers that were built during the Ming Dynasty. The construction work is expected to be completed in 2024.

According to the firm, the Sun Tower is a " more purposeful structure, something that would evoke the ancient rituals of nature-worship while providing much-needed cultural facilities in the newly urbanised district" along with its nod towards history the structure boasts amazing sunrise views across the yellow sea.


"Immediately when we conceived of the design we wanted to reference ancient human rituals, honoring the sun, moon, and stars, and offering a space for reflection and contemplation," said Li Hu and Huang Wenjing, founding partners of Open Architecture.

White Concrete Facade

Sits in the center of a circular plaza, the building is a composite shell structure having a complex design designed in close partnership with engineering firm Arup. The structure is made from two white concrete conical forms that are attached and supported by horizontal ramps and slabs.

Inside the Sun Tower

The concave inner shell of Sun Tower is designed to act as a sound collector that absorbs and amplifies the sound from the sea.

The upper shell contains a bright library and the 'phenomena space' that provides breathtaking views of the sky and ocean.

A myriad of elliptical ring patterns are set in the walkway. " The intersections between the rings and the waterway mark the building shadow's footprint at specific hours on the equinox day," said the firm.

These are linked with low and high tides during normal days. These strategically planned water features offer dynamism to the formation, while also showcasing the city's long history of oceanic culture which is rare in China.
