Brief Update versus Previous Model

I modified my building shape to adopt the inverted configuration because placing and allocation of space (in Module 5 and 6) have been difficult because of the steep envelope. It's really a challenge for my schematic design because the fire exit stair requirements must have their own space and the smoke should not enter it for evacuation. I also realized that having a green landscape would only be a good asset for my building if I am looking from the top. So, I changed it to become inverted so that visitors would just need to look up to appreciate the beauty of the green landscape around the perimeter. See pictures below for updates!!! 🙂😉

#I will still need to update my space budget spreadsheet and bubble diagram for the final deliverable.
