The design for the new library at Saint-Eustach (North of Montréal), is founded on the notion of creating a contemporary project that also shares a story, a story that reveals the historic value of its site. The project symbolizes the reconciliation between the urban form of the Saint-Eustach as it is today, and the history of the riverside site. The concept for the project further integrates fundamental ecologically responsible principles which focus on building compactness, energy economy, and the use of high quality, sustainable materials ensuring the permanence of the project.The parti of the project attempts to distinguish between diverse components of the project that converge with each other, yet compose a homogeneous cohesion. The new building will function as a bridge between the city and nature, tranquility and movement, culture and community. The proposal is thought of as the idea of “living together”, continuously promoting exchange between the library users, staff , and community. The volumetrics and orientation of the new library are derived from a series of major precepts discovered at the beginning of the conception process. The factors include the diverse built and natural context of the site, physical site constraints, and the complex functional program of a modern library. The siting of the library responds to a strong intention to connect the urban form of the town, to the bucolic site. The point of departure is the deformation of a simple, elongated box in which the library program is placed.
