Though the building appears to sit atop a hill, it is actually two levels high, with most of the first floor situated behind a berm. The first level contains Murphy Center's offices and facilities, which are positioned in a square under the arena's seating bowl. The arena floor itself is also on the first level, and is accessible from any of four portals. The main arena concourse makes up the second level, which is entirely above ground, and its exterior walls are composed completely of windows and metal frames. As a result, Murphy Center has earned the nickname "The Glass House". During the day, the interior of the arena is bathed with natural sunlight, so much so that a curtain was installed on the western side of the building to prevent glare during afternoon events. The bleacher sections on the concourse also help to shield the arena floor from the light.
