"Maison Sédimentation" is a historic townhouse located in the old Montreal harbor. The original building has been acquired by a local art foundation, which plans to convert it into a contemporary gallery and cultural center. Preserving the building's authenticity is a priority, but an honest assessment of possibility is necessary. The objective is to construct a gradience of temporality through three different but complementary approaches. Rather than simply adding spaces to accommodate contemporary art, the project is trying to curate sensory experiences.
