Surrounded by a densely wooded area Breakstone Lake is a secluded and quite place where many students come to be alone and bask in the calm of nature. Being a huge lake it is also a place where many go to swim, fish and boat for pleasure or educational purposes as well.

The office where once Charles Xavier sat and taught his students as well as took part in the administration of the institute. Though its headmaster has changed the layout has not. It more then any room retains its 1700’s layout with only the mansion monitoring systems to contrast. Filled with book shelves, an old oak desk and other antiquities once belonging to Xavier this room serves as the heart of the school in many ways.

The offices of the Institutes Faculty. Often these offices are changed due to the constant rotation of Teachers and X-Men.

The War Room is the 'operating center' of the X-Men. This is where briefings are given, missions are planned, and meetings take place. There are various computers and monitors around the War Room, each o f which monitors news feeds from every news network on television and radio, and scans every known frequency for reports on events occurring around the world.

It provides a central and controlled location for training where the X-Men can learn to control and develop their abilities in normal and combat-like situations. The Danger Room employs four high-capacity Shi’ar computers that generate room-filling, 32-bit color images at 300 gigabytes per second, creating hard-light laser constructs of anything imaginable that are virtually indistinguishable from reality. The room itself is quite large, and there is a central control room and observatory overlooking it where the entire room can be controlled by a single person.

These labs are usually used by X-Men scientists and medical personnel. RALPH, the holographic doctor is also installed in the lower-level Medical Lab in the event that another of member of the medical team is unavailable. R&D is where all X-Men equipment is made.

The holding cells are an underground storage facility for those villains that the X-Men deem too unsafe to let roam about freely. The holding cells consist of small titanium-steel cells with the same type of door. Various safety measures can be taken such as erecting an internal force field to back up the titanium-steel walls, a nullification field to 'switch off' mutant abilities, and various other precautions. There are also stasis tubes which hold inhabitants in a state of suspended animation until they are awakened.

Cerebra using a spherical room design, with a suspended walkway leading to the users chair and helmet is a device which primarily amplifies the brainwaves of the user. In the case of telepaths, it enables the user to detect traces of other mutants worldwide. However Cerebra can not only locate mutants, but can also holographically represent recent memories of Mutants, Aliens, Humans and other sentient species in specific geographic locations. Cerebra has been upgraded so that non-telepaths can use the device though this is not advised and only authorized when no telepaths are available.

The Hanger is one of the very few places on the Estate that is actually as it seems it is just an underground area for the storage of the X-Men's aircraft, notably the Blackbird. Devil's Rock and now beneath the basketball court are the primary exit and entry points for the X-Men's aircraft, The Blackbird. Upon departure and landing, a klaxon will sound warning for anyone nearby to vacate the area. Students are advised to move immediately once the klaxon sounds.

The front and back lawns, like any mansion setting, are huge sprawling landscapes of green grass, flowers and the like. In the middle of the school is a small open courtyard which can be reached by several doors where stands in the center the statues of fallen X-Men, most notably Jean Grey and Charles Xavier. Here students can come and pay their respects to the fallen heroes.
