OBERMEYER HELIKA is the general designer of the Hagibor Kappa residential building

The residential complex Hagibor by CRESTYL will expand during its next development phase with a fifth apartment building named Kappa. The nine-story building will offer more than 250 apartments and is expected to serve as a tower-like gateway into the emerging multifunctional neighborhood at the junction of Vinohrady, Žižkov, and Strašnice. The design team from the construction consulting office OBERMEYER Helika a.s. has provided the construction documentation, including static calculations. The specific architectural design is by Ian Bryan Architects, and the general contractor for the construction is Metrostav CZ s.r.o.

"As a designer, you always have to seek solutions somewhere between the architect's vision, the builder's needs, and the investor's possibilities. In the case of Hagibor Kappa, I believe everything is successfully coming together. The collaboration with Metrostav and Ian Bryan Architects is fantastic, and I must say that the initial project brief has been of a very high standard since the beginning," describes Ing. Libor Stránský, lead designer from OBERMEYER Helika.

Light Entry

The building features a striking combination of concrete, glass, and bonded facades. From the sixth above-ground floor, four pyramidally shaped masses rise from a shared base, gradually receding towards the ninth floor. This concept not only maximizes the access of daylight into the courtyard but also creates spacious terraces for individual apartments.

Nature in the City

Great emphasis is placed on the integration of greenery – both on the roofs and in the courtyard – as well as on the overall sustainability of the operation. The green roofs on the first and sixth above-ground floors contribute to reducing the building's carbon footprint, improve the microclimate in the housing units, and support the energy efficiency of the project. Rainwater management is ensured by two retention tanks with a storage capacity, whose water is used for irrigating the richly designed courtyard. Common areas consist of mixed perennial flower beds complemented by shrubs and trees, supported by terrain modeling to ensure the long-term vitality of the greenery. The concept of "nature in the city" for Hagibor was designed by Michel Desvigne in collaboration with the landscape studio L&SCAPE.

Non-Conductive Reinforcement

The building is founded below the groundwater level, with protection against stray currents requiring electrical separation of the structure. "In the central part of the building, where there are no above-ground floors above the basement, there was a risk of flooding the structure. For this reason, we ultimately proposed the use of non-conductive connecting fiberglass reinforcement between the tension piles and the basement columns, which will reliably prevent this risk," explains the static part of the project Ing. Alexandr Šmíd.

The estimated construction period for Hagibor Kappa is October 2025 to December 2027.

Project Details:

Hagibor Kappa: The project includes 9 above-ground floors and 2 underground floors. There are a total of 255 parking spaces in the basement, located in the 1st and 2nd basement levels. Kappa will offer a total of 253 apartments (from 1+kk to 5+kk) including 6 retail units.

Location: The development area of Hagibor is located in Prague 10, at the border of Žižkov and Strašnice, near the Želivského metro station. The addressed area is situated between Vinohradská, Izraelská, and Počernická streets, adjacent to the existing building of Radio Free Europe (RFE). The area was named after the historic Jewish sports club ŽSK Hagibor, which operated here until the German occupation in 1939. The Hebrew word "ha-gibor" translates to hero, strong, or powerful.
