This beauty of a structure was the vision of newly elevated Archbishop Joseph Fiorenza. Ziegler Cooper Architects of Houston was selected to design and Linbeck Group was selected as general contractor. Archbishop Fiorenza presided over a groundbreaking ceremony for the new co-cathedral and construction began shortly afterwards. The building footprint is 27,800 square feet occupying on a site of 37,000 square feet. The co-cathedral will seat 1,820, with room for an additional 200 temporary chairs. The co-cathedral is designed in a simplified Italian Romanesque style with a cruciform shape. The exterior is clad in Indiana Limestone and the interior is accented with 30,000 sq ft of marble. One hundred and eight stained glass panels and windows, including those in the Clerestory, were designed and constructed in Florence, Italy by Mellini Art Glass and Mosaics.
