The process…

We initially started by making a paper sketch using the measurements we took at the site. Our initial sketch was actually of the wrong building, but since the modules were similar, we were able to reuse some of the measurements we originally took with some rough estimates of the upper half of our module. In Rhino, we made use of a lot of reference lines and in order to create the curves, we had to create an extruded cutting object with filleted corners. Using the BooleanDifference command, we were able to cut out the shape you see above.
