The interior architectural construction of all ten stations of Budapest’s Metro Line 4, along with the smaller surface‑level landscaping works associated with the project, showcase Swietelsky’s expertise and high‑quality workmanship. The execution resulted in modern station spaces with unique visual identities, representing outstanding quality not only in terms of aesthetics but also from a technical perspective. The complexity of the project is reflected in the fact that, in addition to the interior installations, the coordinated implementation of numerous related technical systems was also part of the task.

This exceptional professional performance was recognised by the industry in 2015, when Swietelsky received the Construction Industry Award of Excellence in the “Transport Facilities” category.
