The Urban Beat
Live where the heart of the city beats

14 exclusive 1–3 room apartments

In a prime city center location in Bonn, 14 high-quality apartments are being created that combine urban living with historic charm and modern comfort. The units are spread across two buildings – a lovingly renovated period building from 1870 and a sleek new-build at the rear of the plot. Both are connected by a newly constructed central building.

The approx. 43-meter-deep plot stretches from Thomas-Mann-Straße to Noeggerathstraße. Access to the period building is from Thomas-Mann-Straße, while the new building is accessed via Noeggerathstraße. The 14 apartments predominantly offer one to two rooms and living areas between approx. 29 m² and 84 m² – ideal for owner-occupiers or investors.

The apartments are finished to a high standard: parquet flooring, underfloor heating, large-format tiles, triple-glazed windows, and other premium features create a pleasant living atmosphere. 12 of the 14 apartments also have a balcony, terrace, or loggia.

Special attention has been paid to energy efficiency: the period building is being renovated to KfW-85-EE efficiency standard, while the new-build meets the even higher KfW-55-EE standard. Heating is provided efficiently and sustainably via a modern air-to-water heat pump.

These apartments not only provide attractive living but also represent a sound investment. Comparable rental units currently achieve cold rents of €21 to €23/m². In the period building, 2.5% linear depreciation applies, while in the new-build, up to 5% declining-balance depreciation may be used (please consult your tax advisor – all information without guarantee).

The purchase price is due upon completion. We would be happy to show you the current construction status in a personal viewing. We look forward to hearing from you!

In the heart of Bonn

Location description

Bonn city center is a district on the left bank of the Rhine and forms the heart of the federal city. It borders the districts of Bonn-Castell, Nordstadt, Weststadt, and Südstadt, and lies directly on the eastern banks of the Rhine.

The pedestrian zone – car-free since 1967 – stretches from Bertha-von-Suttner-Platz through Marktplatz, Remigiusplatz, and Münsterplatz to the central station. The district also includes the historic riverside quarter and the northern area around Stiftsplatz.

The University of Bonn, with its historic main building by the Hofgarten, shapes the cityscape and adds an academic flair. Additional institutes are located in Südstadt and Nordstadt – all within walking distance.

Also located in Bonn are renowned scientific institutions such as:

  • the Federal Institute for Vocational Education and Training (BIBB)
  • the Center for Development Research (ZEF)
  • the German Institute of Development and Sustainability (IDOS)
  • the Bonn International Center for Information Technology (BIC)
  • the UN Campus with over 20 United Nations organizations

Bonn is also economically well-connected: the headquarters of Deutsche Telekom AG, Deutsche Post DHL Group, Postbank, and numerous federal authorities and ministries are nearby – easily accessible by bike or public transport.

The Hofgarten, with its wide lawns, mature trees, and modern playground, is a favorite spot for families, students, and those seeking relaxation. The city center also offers numerous shopping and dining options, excellent childcare, and convenient access to schools in surrounding neighborhoods.

Thanks to the centrally located main station – used daily by around 67,000 travelers – transportation links are excellent. The B9 and B56 ensure fast car access, for example via the Kennedy Bridge to Beuel. Cologne/Bonn Airport is reachable in about 25 minutes.
