Open Architecture has announced the topping out of its project Chapel of Sound, with the pouring of its broad concrete roof.
The project, which is expected to open in 2020, includes a semi-outdoor amphitheater, an outdoor stage, and viewing platforms, overlooking the mountainous rural area of the Jinshanling Great Wall, outside Beijing, China.
Its roof will be the largest flat surface in the project. It took the workers 24 hours to complete the slab having worked day and night.
Chapel of Sound is situated near the northern boundary of Beijing municipality, a rural area where most of its population has migrated due to the lack of resources. The project aims to vitalise the barren mountain area, inviting locals and investors back to the land.
The design team developed the project based on the spatial needs of a music hall, as well as the site’s landscape. The main structure consists of two interconnected concrete shells: the outer shell is an inverted conical shape, while the inner one is formed by its acoustic needs. The shells are treated with hard surfaces and punctured on a few enclosed surfaces to provide proper acoustics within the space. The openings also frame the surrounding views of the sky and the valley, as well as bring in sunlight at different times of the day.
