The church was built with buff colored Gizri stone and the architectural design made it unique.

The church followed a Romanesque[6] layout which made it stand out compared to the buildings located around.

At the top of the tower, since there were no lighthouses, it was given beacons to help ships[7] in the Karachi Harbour.

In 1904, Captain John Hill and Chief Engineer John Brunton, reviewed the cathedral and found that the foundation was showing signs of weakness and removed[8] the top two stories, giving the tower a new height of 115 feet.
