Dedicated to Tony Stark’s father this room contains a multitude of weapons created for the use of the Avengers in support of their many missions.

A portion of the mansion's third floor served as a hangar for the Avengers' quinjets, their primary mode of transportation. Here the most advanced systems Tony Stark could create monitor, maintain and repair the several jets used by the Avengers.

The primary training and sparring area’s of the Avengers. These rooms contain all the Avengers need to help maintain their peak physical status. A Weight Room, Track Room, Gymnastics Room, Pool, Combat Simulation Room (Much like the X-Men’s Danger room but less advanced), Sparring Room and Much more are housed in this area.

24 rooms to house Avengers who wish to reside in the mansion, as well as Jarvis's quarters. As the Avengers roster often shuffles many of the rooms are left open and or switched to suit new occupant’s desires. Only two rooms have remained unchanged since the reconstruction, Captain America’s and Tony Starks.

When entering the house one would think it to be the home of some wealthy millionaire. The walls are finished oak with paintings and tapestries and the floors polished hard wood. In the Sitting Room visitors wait to be announced and greeted by the Avengers. The Lounge is where the Avengers can relax on their time off, play pool, sit and read, watch television or other such leisurely activities.
