St. Paul the Apostle Church, fronts Portage Avenue with a distinctive and spare slab of white-painted diamond patterned and textured concrete block. The large plane, seemingly floating, surmounts a ground level wall of red brick and windows, all set back from the sidewalk with a garden barrier. This north, Portage Avenue wall (paired with a matching south wall) is in fact the side of the church, which in typical church form is oriented on an east - west axis. The building, a distinctively modernist form, was designed by noted Winnipeg architects Waisman Ross, in 1959. Originally a large wall of coloured glass windows and wood detailing marked the east entrance, which has been modified with the addition of a narthex of brick and glass featuring a peaked pediment at centre. This peak mirrors that of the original church architecture, whose simplified form was of a simple composition: glass end walls, masonry side walls, topped by a shallow gable. Distinction was added, in part, through a gentle melding with the slightly hilly setting, adjacent to the Assiniboine River. The west wall preserves the original design of the end walls, with a broad span of coloured glass windows and wood detailing.
