Trzonolinowiec

Trzonolinowiec is a residential tower in Wrocław, Poland, standing 41 meters (135 feet) tall and built on an unusual principle of steel cables supporting hanging floors. The 44 apartments spread across 12 stories are each suspended from a central concrete core that carries the entire load.

Construction started in 1961 using an uncommon method: builders began from the top floor downward, with hydraulic jacks pushing each new level underneath the previous one. This experimental technique was intended to demonstrate that Poland could pursue new directions in construction after the war.

The tower earned the nickname 'Artist House' during the 1970s, when several performers, painters, and theater professionals chose to live there. The concentration of creative residents gave the address a bohemian character that shaped its reputation across the city for years.

The building stands at 72-74 Kościuszki Street and underwent technical evaluations in 2023 to determine the condition of its structure and maintenance needs. Access is only for residents and their guests, as it remains a private multifamily residence.

The top-down construction method is rare in building history and was applied here for the first time in Poland. The approach shortened construction time and ensured that each floor fit precisely under the other, reversing the usual building sequence.
