8. Philip Johnson, the Creator of the Glass House, Designed the Building’s Interior

While the Seagram Building’s exterior is most known for leaping architectural boundaries, its interior was also innovative. Once Lambert chose Mies to design the exterior, Mies decided to make American architect Philip Johnson responsible for its interior. (Fun fact: Lambert and the executives chose the Seagram Building’s architect in the Glass House’s living room).

The office space above the building’s crisp lobby are lit with ceiling panel lights and receive as much natural lighting as possible since the floor to ceiling windows are glass panes with grey topaz. He also used a lot of marble and bronze, contributing to its overall decorative nature (and hefty price). There are also vertical bars in the window panes to match and highlight the building’s vertical exterior.
