German property developer Bewocon has unveiled plans for a 150-metre-high skyscraper in Berlin, which could become the city's tallest building.

Designed by German firm Ortner & Ortner, the Alexander Berlins Capital Tower would be 25 metres higher than the city's current tallest building, the 125-metre-high Park Inn Berlin Alexanderplatz.

If completed according to schedule, it could beat other skyscrapers proposed for the German capital, including a 150-metre-high tower by Frank Gehry.

The city does have a taller structure, although it is not a building. The Fernsehturm Berlin, also known as the Berlin TV Tower, is 368 metres.

Plans for the new skyscraper were first revealed in 1994 as part of a wider masterplan for the city.

Bewocon filed a planning application for the project last month, but is confident that the project will be granted permission by September, allowing construction to begin at the end of the year.

The plans for the Alexander Berlins Capital (ABC) Tower, commonly known as the Alexander Tower, include 475 residential apartments across 39 floors, with spa and gym facilities, private cinema, residents terrace and club levels, as well as underground parking facilities for cars and bicycles.
