H. J. High has been constructing religious facilities in the Central Florida region for over 75 years. We have built religious projects ranging from simple church additions to mega-churches, which are larger auditorium-type buildings that can hold 2,000 people or more. In fact, H. J. High built two of the first mega-churches in Florida, including First Baptist Church of Orlando and Calvary Assembly of God – both containing more than 6,000 seats.
