It is surrounded by a 4 lane athletics field with tartan of high specifications and has all the required facility infrastructures needed for throwing and jumping sports (broad, high and triple jump). Finally, there is a tier of 1,200 seats and locker rooms fully equipped with showers and WCs. All areas are designed in a way allowing the use by athletes facing movement problems.

The upper part of the building has a 117 m. long and 10 m. wide athletics field with tartan and four lanes. On the ground floor there is an indoor gym for pole vault training as well as training areas for the sports of gymnastics, weight lifting, boxing, wrestling, Judo and Tae Kwon Do. It has three fully equipped locker rooms and WCs as well as warming-up areas. The indoor training hall is connected via an underground passage to the main Stadium (Building 1).

On the eastern side of the building towards the junction of the streets Agiou Dimitriou and Katsimidi is currently (2006) being constructed a new athletics field especially for throwing sports.
