My big ideas include multifunctionality and biophilia in dense areas.
I have included a picture of the highline, while it is not a building, it does an effective job an showing the transport/walkability potential of infrastructure like a building. I think buildings could be interesting mediums for people to use passively in order to get to another place.
Continuing on the theme of multifunctionality, I appreciate the concept of biophilia inside buildings. For example, this wall serves as a barrier, but it also provides greener than can help create a healthy/immersive tone in the room.
Lastly, another big idea I would like to include is the use of skylights and other passive forms of light like in the Bradbury Building. Also, this building embraces open space between the floors so this is another concept I would like to incorporate.
