Later, wings were added to accommodate classrooms and dormitories, but in 1915 the northern part of the building suffered very seriously during the floods of that year, and the Nuns were compelled to spend entire nights under umbrellas. Arches gave way and the roof of the Chapel collapsed crushing every priedieu and chair under its weight but the Sisters escaped death. After this the northern part of the building had to be pulled down and the present handsome edifice was built. There are four houses - Ball (red), Hart (green), Hogan (yellow), and Ward (blue). Ward house is dedicated to the foundress of Loreto worldwide, Mary Ward. Ball house is dedicated to Teresa Ball . Hart house is dedicated to Mother Delphine Hart. Hogan house is dedicated to Mother Joseph Hogan.
