Flat Iron Building

The Flat Iron Building was finished in 1902. The architects were Daniel Burnham + John Wellborn Root. The building height is 285 feet. There are only 22 floors. The architectual style is a classic greek column. The materials they used were lime stone and glazed terra cotta facade.
The color of the building from what me and Stephony can tell is gray there are some repeated shapes but there are mostly rectangles and squares which are the windows.
The only special shape is the triangle.
