For my thesis I explored the idea of the mask in relation to architecture. For my project I designed an art gallery located in Georgetown Washington DC which is composed of three layers: a structural layer, an environmental casing, and an outer layer. Theoretical parallels are drawn between the outer layer of the gallery and what is commonly referred to as a mask. Additionally, I explored the interaction between the layers of the gallery. The distinguishing characteristics of the building include the tri-facade mask, the unique spaces in between the gallery's layers, the glass system, the mask's ghost effect, and the floor system.
