Lateral elevation of the presbytery reconstruction, by architect Théo Daoust.

Pointe-Claire's first presbytery was erected in 1705 and enlarged in 1786. It was demolished in 1848, and replaced by a large, traditional house, built by contractor Narcissus Prévost and master carpenter Basile Daoust. The new structure had rough stone masonry on three sides, while the main facade was covered in bush-hammered stone. A ridge roof with dormer windows topped the walls, and the protruding drip moulding sheltered a front porch.

Most of the masonry of this residence was preserved, despite a major transformation of the building in 1913, according to plans by architect Théo Daoust. A floor was added, plus a mansard roof, and many dormer windows crowned with finials. A new porch with ionic columns surrounded the structure on three sides. A balcony, with a pyramidal roof and finial, rests over the porch in the centre of the main facade. Slate covers the roof and the exterior walls on the second floor.

In 1954, repair work was carried out eliminating the cornice mouldings and other decorative elements, but most of the exterior still survives.
