Sometimes we stumble upon something that doesn’t need any explanation, because there’s simply nothing to explain. The project ‘Balcon Additionnel’ by French artist Julien Berthier is such a piece of work. In 2008, he designed a plug-on Haussmannian-style balcony that can be easily attached to all kinds of buildings. Berthier’s ‘balcon additionnel’ cannot be separated from the boom-truck that allows it to be quickly fitted or removed. The picture above shows how a modernist building, which I would describe as an ‘intentionally blank page’ in printing terms, gets an instant classical extension.
