InCity Immobilien AG ("InCity AG") just laid the foundation stone for the "Delta" office scheme at Lilienthal Business City near the new Berlin-Brandenburg Airport (BER). The prestigious new building with its gross floor area of around 12,000 square metres will serve as future gateway to Lilienthal Business City, an office park only four kilometres from the airport. The start of construction also signals that the further development of Lilienthal Business City has resumed. Its planned expansion will proceed in several construction stages and introduce offices and hotels but will also include upgrades to the existing buildings. The first construction works for the "Delta" new-build project are already under way, having started in July 2021. The new office scheme about to be created was certified for the "Gold" standard of the DGNB German Sustainable Building Council. Designed by STP Architekten Berlin, it stands out with its conspicuous form, elegant facade and flexible layout structure. The floor plan takes the shape of a triangle with rounded corners.
