Leland Gray has years of experience with theaters and large gathering spaces. Perhaps one of his largest such projects was as senior design architect for the Church of Jesus Christ of Latter Day Saints, when he oversaw design of the 21,000 seat Conference Center in Salt Lake City, Utah. In addition to the main auditorium, an additional 950 seat auditorium plays host to smaller events and plays. Beyond the conference center, Lee provided design, construction administration, and quality assurance inspection services for religious and educational projects in the USA and Canada for 25 years, as design architect for the LDS Church. Lee's experience with theater design and design of other assembly areas began early. Years before going into architecture, his family owned a movie theater in Sandpoint, Idaho. He ran the theater during his high school and college years, giving him valuable theater operation experience and understanding of the equipment.
In 1970, shortly out of architecture school, Lee designed the Wenatchee High School in Wenatchee, Washington. It was one of the largest award winning high schools for its time. It has a large auditorium with a stage.
Lee designed and provided construction administration for recreation facilities that were part of housing complexes, motor hotels, and apartment and condominium complexes in Washington state in the 1970’s.
Lee’s role as an architect extends beyond design. As the Senior Design Architect for the LDS Church, he worked directly with corporate management creating standard designs. In addition, he managed staff engineers and led the production of construction documents for temples, meetinghouses, seminary buildings for high schools, institute buildings for college campuses, and welfare building such as food storehouses, canneries, and clothing distribution stores.
As Principal of Leland A. Gray Architects, Lee creates designs and budgets for clients. In addition, he produces construction documents and coordinates the work of consultants.
