The building complex, Sigma Block, is located in the most prominent area of Kalamaria and specifically at the junction of El. Venizelou, an extension of Adrianoupoleos & Ethnikis Antistaseos streets. This place is right on the eastern entrance and exit of the city with direct access to all public transportation, while the residential neighborhood and upscale retailing stores make it a unique spot. The complex consists of three independent six-storey buildings and all the spaces have great 360 degree north-south views since there is no adjacent bulding  nearby and will remain so in the future.

The developments have been imaginatively arranged to provide residents with generous accommodation and maximum daylight whilst achieving the necessary degree of privacy for its occupants. Each building has a separate entrance while sharing a common atrium providing a secure and private environment for residents to enjoy. On the ground level, around the buildings there are commercial stores with large facades overlooking the two main streets. The buildings were designed to accommodate mixed uses such as offices including dental offices, but mostly apartments / residences.

The complex has also underground parking and storage space for the needs of the users.
