Kloosterstraat 31, Antwerp, Belgium
I studied architecture in high school. The building below, Kloosterstraat 31 in Antwerp, was going to be protected, but the original blueprints were lost. The assignment for our class was to re-create the drawings. I volunteered to do the façade. The drawing below is a reconstruction on PC based on my notebooks from that time. (Everything was done by hand; PCs didn't exist yet.)
My original drawing was at scale 1:20 (about A1 format).
