O2 universum

Commercial construction

The construction is connected to the construction of the O2 Arena in Prague 9 and is operationally and technologically linked to it. The multifunctional O2 Universum Center forms a space not only for concerts, but also international events and congresses.

Basic information

Project Investor:

Bestsport, a.s.

Project Designer:

ATIP a.s.

Project Duration:

10/2017 – 02/2020


The project deals with the reconstruction of the existing O2 small arena in Prague. At the level of Českomoravská Street, the entrance parts of the congress center were newly completed and new congress halls were built, including a completely new steel structure above Hall A. The layout is designed in such a way that the congress part is a separate operational unit, which is connected to the Oarena and which uses the previously prepared capacities of the technical and operational infrastructure. 

For sports purposes, a minimum clear height of 12.5 m has been ensured in Hall A. Six large height-adjustable circular light fixtures are installed here. Some halls can be further divided using sliding partitions into separate, acoustically separated spaces.

    Exceptional Nature of Project

    During the reconstruction of the O2 small arena, hydro-demolition (removal of concrete by water blasting) was used. An entrance awning with a 1,800 m2 steel structure was built, while the steel trusses above Hall A and the steel structure above Hall B, which carries the original concrete ceiling panels, were replaced.
