Era, a.s. is a manufacturer of air traffic safety systems for both military and civil purposes. Its production and administrative premises are located in the traditional industrial part of Pardubice.
The original production building, built in the 1990s, was the oldest part of the complex. Since its construction, it has served as a production and administrative building. Gradually other buildings were built in the complex. First two assembly halls, then a new administrative building was completed in 2017 (Jiří Bíza, Ondřej Hilský, Pavel Táborský).
The production capacity of the premises gradually ceased to be sufficient and the condition of the 30-year-old production building was also not satisfactory. The company had been considering the reconstruction and extension of the production hall for some time, but decided on the final form in 2020.
A condition of the renovation and extension was that production would not be interrupted during the entire construction process. It was not possible to simplify the process by removing the existing building and building on greenfield sites.
The first addition was a three-storey office wing on the north side of the existing building. Subsequently, the original three-bay, 46x50-metre production hall was gradually renovated. In order not to interrupt, but also for the gradual increase in production, the individual steps of the reconstruction were carefully planned. The relatively small size of the site was also a limitation for the construction.
The overall result is a logistically well-functioning production building with a unified appearance, dominated by a high-rise mast for the installation and testing of technology.
The completed structure has been given a new cladding which significantly improves the thermal performance of the building. The motif used to articulate the entire envelope is based on the design of the truss masts used for the technology. The facade articulation reduces the scale and completes the overall expression of the building. Both the window openings of the original building and the new extension are integrated into the chosen grid pattern. The top floor of the extension to the north is illuminated by a glazed façade.

The original building was structurally designed as a prefabricated skeleton, the extension is a skeleton, monolithic. The façade is designed as a heavy envelope with higher demands on design, durability and maintenance. To reduce the energy consumption of the building, photovoltaic panels are installed on the roof.
