Cathedral Sanctuario de Guadalupe Dallas, Texas Alternative site development plans for the redevelopment of an existing site immediately adjacent to the existing historic cathedral in the Dallas Arts District. Portions of the building were to be constructed on top of the underground parking garage constructed some eight years earlier, designed as the foundation for a thirty four story office building. Initial plans called for a new parish Hall capable of seating 500 plus people, as many as seventeen new classrooms and administrative space for at least twelve staff members, totally approximately 41,000 square feet. Plans included provision for the expansion of the school to another level, and the addition of a Chapel or Exhibition Hall as part of the Arts District public accommodations requirements. The final design included 35,000 square feet, with the administration area moved to the basement level under the Parish Hall, and completion of the seventeen classrooms.
