The project of preserving the listed buildings of the gas plant was a priority project. The works extended to areas with an obligation of environmental rehabilitation. Both the buildings and the neighbouring ground contained hazardous waste, which had to be removed and disposed of.
As a result of the project, the building was restored to its original glow. Works included a complete restoration of the facade, building the structures that ensure the functionality of the interior spaces as well as a complete renovation of the onion domes. During the restoration of the stones of the facade, led by a restoration expert, contemporary mortar was used, applied with a special technique.
During the restoration it became clear that the shell structure of the northern tower would have to be removed due to its unsafe condition, and a new one would have to be constructed. This was only possible using a specially built modular scaffold; the shell formwork was also constructed specifically for this project.
