Circular window on concrete building features black tic-tac-toe frames.
A distant view of a circular window on the side of a white chisel slate textured concrete building. The window is embedded into the side of the building. Around the window is a black circular frame. There are two vertical frames and two horizontal frames extending over the window forming a tic-tac-toe shape over the window. A shadow of the inner part of the side of the building that the window is embedded into is being cast over the majority of the window. Natural light is reaching the bottom right side of the circular window.
