UNS has completed the Bridge Tower in Warsaw, Poland, a project that brings together the new office tower with the historic Bellona building.
Standing at 174-metres tall, the Bridge Tower integrates innovation and sustainability with a structure that honours the city’s heritage.
The design for the tower visually complements the historic Bellona building, a locally protected monument, through a shared lobby that serves as the main entrance for both buildings.
The Bridge Tower offers 47,000 square metres of office space, with 280 parking spaces, bicycle facilities and charging stations for electric vehicles.
Ben van Berkel, Founder and Principal Architect, UNS, said: *“*By carefully blending the historic Bellona building with a modern high-rise, The Bridge Tower created a space that not only respects history but also embraces innovation.
“This connection is more than just visual – it is functional, sustainable, and designed to enhance the everyday experience of its users.”
The Bridge Tower integrates technological innovation and sustainability in addition to its heritage structure. The tower will be powered entirely with clean energy sources, including nearby photovoltaic farms.
Its advanced Building Energy Management System will monitor and optimise energy use, while innovative features like vacuum sewer technology will reduce water consumption in toilets by up to 75 per cent, setting a new standard for resource efficiency.
The Bridge Tower will incorporate its proprietary Signal OS, a smart operating system that enables sustainable management of water, energy, and air quality.
Additionally, the building will feature health functions, including virucidal UV lamps in lifts and air handling units, ensuring a safe environment.
Through its commitment to sustainability and technological advancements, the project not only preserves the historical significance of the Bellona building, but also sets a benchmark for future-forward urban development.
