Brussels: thurn & taxis

I am running behind with my sketches, and don't have enough time to sketch at present. Regular work, the usual hobbies, teaching architect students to draw and organizing a sketching workshop in Volterra (Italy).
So this is a leftover of a quick sketch I made during an architectural visit with the students to Brussels.
It's an abandoned and burned out railway house on a former trainyard, called thurn & taxis. The new office towers are slowly creeping towards this part of the town.
