26th August. I was drawing this building site in Fatbursparken when the site manager came past and had a look, and offered to show me around the building in the sketch. It's a beautiful old 18C building, on the heritage list, but they need to build a new train tunnel underneath it. So the solution is to lift it up by a couple of mm, build the tunnel underneath, and put it back down again onto the roof of the tunnel. As you do. It's amazing what you can learn from doing a drawing! I'll put more drawings of this on flickr, and go back and do some more when it stops raining.
