An interior view of a building's ceiling with metal beams and glass panels. The structure is composed of multiple layers, each featuring white metal beams arranged in a grid pattern. The top layer consists entirely of glass panels that allow natural light to enter the room, while the bottom two layers have only partial coverage of glass panels, allowing for a mix of natural and artificial lighting. This design suggests that the building may be designed with energy efficiency and sustainability in mind, as it allows for maximum use of natural light during the day and reduces the need for artificial lighting.
