K1 (building)

Plans were made to construct a larger number of similarly tall skyscrapers in the Grzegórzki district (referred to as "Kraków's Manhattan").

In 1975, the building was left in an unfinished state—load-bearing tests revealed that the structure could not support the weight of the printing machines needed for newspaper production.

The completed building had an orange-yellow color and, for the time, innovative windows coated with a very thin layer of gold, which, however, proved to be highly non-durable and not resistant to external conditions.

The architectural redesign was carried out by Krzysztof Kiendra as the lead designer, with Wacław Kujbida and Adam Reczek as co-designers, in collaboration with Witold Nowak, Marta Lipska, Zbigniew Filipek, Thomas Wahlberg, Marius Lorentzen, and Jarosław Dąbrowski.

The modernization of the office building was awarded the title "Construction of the Year 1998" under the patronage of the Marshal of the Małopolska Region for its design and execution.
