I have been experimenting with the following design on sketchup:
Below are a few views of the models upper ground and shape of the below studio. I used the arcs that are part of the middle show-ground as a way to allow natural light into the underground studio. The whole structure (minus the arcs) is highly geometric to create a sense of unity in the building as a whole.
As compared to my first sketch, I have now learnt how to integrate a landscape into the design. I have also learnt how to make a slightly more sophisticated and proportional looking building.
