interior of a building under construction. The camera moves through a stairwell, where three workers in safety vests and hard hats are present. Scaffolding is erected along the stairs and in front of a large window. The stair treads are blue. Beyond the stairwell, a room is visible with a blue protective covering on the floor and a large sliding glass door leading to an outdoor balcony with a view of the city. The walls are white, and the room appears to be in the process of being finished. The building exterior is visible through the large window.
