Not a lot of changes have been made to the first and underground floors. Here, you can see how you can get to the ground floor from the first. The additions made were the columns and furnitures to portray what each space is.
This perspective shows the northern facade of the building looking from the inside of the sunken garden.
The second floor was edited. A ramp was added since the exhibition space is at a higher level and two double height spaces are added next to the ramp and at the northern end. The archival space has been made smaller so that people can only accessed the restrooms before entering the exhibition space. Theater spaces remain the same with an addition of benches along the southern columns so that visitors can sit and look out at the administration building.
This perspective shows how one can be standing on the second floor and look down and see into the sunken garden at the underground level.
In order to show the double height spaces and height shift of the exhibition, I drew a sectional axonometric. This axon shows not only those mentioned earlier but also the overhang space, entrance, sunken garden and how each space is related to each other.
Last but not least, I build a massing model. It shows the sunken garden, the anchor that connects the theater space, the open middle section of the building and the overhanging mass. You may not be able to see the interior spaces inside but the general shape of the building is clearly portrayed in the model.
