Upper One underground construction starts

● Developer STRABAG Real Estate is starting construction of the underground floors of the Upper One complex.

● According to the schedule, the investment will be completed in 2026.

Warsaw, 21 September 2023 – Construction of the five underground floors of Warsaw’s Upper One office and hotel complex has begun. The first phase of underground works will involve the construction of diaphragm walls containing the geothermal installation. This phase will be completed later this year.

After the demolition of Atrium International, which lasted seven months, the developer is entering the next phase of works. On the plot on Jana Pawła II Avenue, construction work is being carried out on the diaphragm walls and the construction of the underground storeys of the office tower, with a target height of 131.5 metres, and the hotel section.

“The Atrium International building had two underground storeys. Keeping in mind the requirements of the tenants, the Upper One project envisages five of them. There will be a garage with more than 200 parking spaces. Thus, our project will provide modern spatial and functional solutions for the future users of the investment. This is particularly important in the centres of large cities, where the availability of parking space is limited,” explains Łukasz Ciesielski, Managing Director of the development company STRABAG Real Estate.

Construction of the diaphragm walls is currently underway and will be completed in the fourth quarter of this year. The next stage will be the construction of the underground structures. According to the schedule, the entire Upper One complex will be completed in 2026. It will provide the capital’s market with 35,900 sq m, sustainable and designed with tenant wellbeing in mind, of office space and approximately 11,000 sq m of hotel space.
Upper One will be distinguished by a light-sculpted, asymmetrical façade, pulsating with the movement of five glass lifts. The building will combine advanced building technologies and modern, elegant architecture. The project was designed by the Polish studio Medusa Group and the general contractor is the construction company STRABAG.
