The temple was a Class "A" fireproof building constructed of concrete and steel designed by Brook Hawkins. The structure's main architectural feature is its large, unsupported concrete dome coated with a mixture of ground abalone shells. The dome's interior was painted azure blue, with fleecy clouds, a reminder to "work while it's day" and "to look for His coming". McPherson insisted on a bright, joyous setting, avoiding any reminder of sin from either artwork or motto. In back of the pulpit was her theme verse from Hebrews 13:8: "Jesus Christ the same yesterday, and today and forever." She later said that she loved "every stone in Angelus Temple...I love to touch its walls, its altar...I look to its high vaulted dome..." but no part of the church pleased her more than the magnificent Kimball pipe organ which always soothed her and brought her peace of mind.
