The name comes from wings featured in the building's emblem, symbolizing the connection to labor unions and workers' movements of that era.The design reflects the pride of these institutions and still shapes how people understand its role in the city today.
The building can be viewed from outside and offers a good starting point for exploring the neighborhood's architecture.Since it is an office building, interior access is limited, but the exterior facade clearly displays its rationalist design features.
The building was originally equipped with an underground bunker designed to provide shelter during conflicts, a feature that reflects the politically uncertain times of its construction.This defensive structure was later completely converted into production studios, transforming its original protective purpose.
