My inspiration was Torre Arcos Bosques II. I was originally looking at famous buildings in Mexico when I found Torre Arcos Bosques II in my search. This building is composed of two twin towers united in-between.
I started by getting a picture on Google Earth of the 2D view (top view) of the building.
I started by tracing both towers and the middle piece that unite them in-between. Once I have traced everything, I extruded everything up and started tracing all the windows on the sides.
Once I extruded all windows, I added any extra features and hollow the inside circle up.
Here is the drawing of Torre Arcos Bosques II with some dimensions
