UBM breaks ground for HAVN residential and office project


  • 44 condominiums and 5 office units on the banks of the River Rhine
  • Clear commitment to residential construction – even under difficult conditions
  • DGNB pre-certification in gold


Mainz, 25 January 2024. The ground-breaking ceremony for the exclusive HAVN residential and office building developed by UBM Development marks another prominent addition to the Zollhafen Mainz. Located directly on the waterfront promenade of the Nordmole, the project comprises 44 condominiums and 5 office units with a total of around 6,700 square meters of gross floor area above ground. “With each of our projects in Mainz Zollhafen, we want to create something very special to do justice to this unique location,” explains Sabine Lennarz, Head of UBM’s Frankfurt branch, “HAVN is a real gem in this context, with its architecture and overall aesthetics designed to showcase the premium location on the banks of the Rhine as a unique lifestyle experience for residents.”

The elegant architecture of the building, which was designed by happarchitecture, references the unique location on the waterfront with its wave-shaped balconies and a clinker brick facade that shimmers in shades of green. The apartments offer space for a wide variety of lifestyles. Both compact city apartments and spacious family apartments with more than 100 square meters are being developed. Many of the apartments are designed to be barrier-free and all have at least one balcony or, on the first floor, a terrace plus garden area in the green courtyard facing the River Rhine. For the perfect view of the Rhine panorama, HAVN also has an elaborately designed and landscaped communal roof terrace that is accessible to all residents.

Smart features

The sustainability concept of the DGNB Gold pre-certified project places particular emphasis on landscaping the outdoor areas and roof garden to promote biodiversity as well as a sustainable energy supply using environmentally friendly district heating. Heating, lighting, sun protection and video access control are operated via a user-friendly app in the smart home system. The underground car park has a total of 26 parking spaces, which are pre-equipped for the connection of wall boxes, as well as a bright and spacious bicycle garage. HAVN is scheduled for completion in Q1/2026.

Following the Timber Peak timber hybrid high-rise project, HAVN is the second of four building plots that UBM acquired in the Mainz customs port in March 2022. A total of more than 42,000 m2 of floor space will be developed on these four plots, around 75 percent of which will be residential and 25 percent commercial/office. Following the gradual realization of these developments, UBM expects sales revenues of more than €300 million.

Timber Peak and HAVN are not the first UBM projects in Zollhafen Mainz. The “Waterkant” and “Kaufmannshof” residential projects and a Super 8 Hotel have already been realized and sold. Also currently under construction is the “Flößerhof” project, which is being developed in partnership with CA Immo.

UBM Development is one of the leading developers of timber construction projects in Europe. The strategic focus is on green buildings and smart offices in major cities such as Vienna, Munich, Frankfurt and Prague. The Platin rating from EcoVadis and the Prime status from ISS ESG confirm the consistent focus on sustainability. With 150 years of experience, UBM offers all development services from planning to commercialization from a single source. The company’s shares are listed on the Prime Market of the Vienna Stock Exchange, the segment with the highest transparency requirements.
