[Image: Originally an ad for the Cité de l’Architecture in Paris].
I originally spotted this image a while back via the Tumblr Architectural Models, but it appears actually to have been created as part of an ad campaign for the Cité de l’Architecture in Paris.
Whatever its actual provenance might be, I love the idea of leaving in place the partially excavated backdrop out of which an architectural model emerges, the rough material matrix—be it wood, rock, or 3D-misprinted plastic—whose precise spatial shaping becomes all the more clear when you can compare a form with its formless origins.
