CHYBIK + KRISTOF Unveiled the Tallest Tower in the Czech Republic

Hammering home the city of Ostrava’s transformation from an industrial coal and metal mining center in the 20^th century to the modern metropolis it is today, CHYBIK + KRISTOF has revealed plans for the Czech Republic’s tallest building: Ostrava Tower.

Subtly shaped like an X, the 56-story, the 235-meters-tall tower is the latest piece of urban infill for Ostrava, as industrial lots have given way to new residential and cultural buildings such as Steven Holl’s 2019 concert hall.

Flaring at the base and pinnacle and cinched at the waist with a 90-degree turn between the top and bottom, each of the three points contains public spaces; a barrier-free ground floor to allow for a seamless transition for pedestrians from the plaza at base level and the local bus terminal, and a public bar, cafe, and restaurant with panoramic views of the city at the very top.

In between those two terminuses will sit residential units, offices, a hotel, retail, and a “congress centre”.

“Rethinking the typology of the skyscraper,” said architect Michal Kristof, co-founder of CHK, in the project’s announcement, “and its function to serve the public and activate the urban environment, one of our core missions was to create a positive social impact in the heart of Ostrava. The studio’s intention was to create a simple but powerful form that acts as a beacon into the city center.”

Ostrava Tower will be wrapped in a “jittering,” pleated glass facade that closely follows the jagged floor plates of each story.

Aside from the aesthetic flair, increasing the complexity of the tower’s edges also corresponds to an increase in viewing angles.

A copper-colored metal brise-soleil will top the roof deck and undulate with the same sharp curves of the building below while shading guests.
