Below is the "Tea cup exercise" which we had to draw and render the tea cup in scale 1:1.
Above is the Mock-Up for our final drawing. I think the bridge of the Botta House is certainly the most sight catching element. So I was thinking to place the plans as a horizontal line to make a coherent feeling to the bridge.
An in-class exercise which is a perspective drawing of the house that we chose. I have choosen the Botta House, which is this building has both vertical and horizontal sense.

Above is an in-class exercise, what we had to do was to mark the correct shadow.

Plans , section
and elevation which were drawn on tracing paper.
The FINAL DRAWING of the Botta House. I really like the bridge that extending along to the cliff, so I emphasis that by colouring it. To get a balance, I also coloured the bridges in the section, elevation and plans. The layout of the plans is an imitation of the form of the house, I tried to create a coherent feeling in the drawing.
