CA Immo and UBM Development start construction of the Kaufmannshof in the Zollhafen Mainz district

Mainz, 29.07.2020—CA Immo and UBM Development have started construction of the Kaufmannshof residential and office building in the Zollhafen Mainz district. The building will have total gross floor space of around 8,600 m², of which approx. 55% will be for residential and 45% for office use. Completion of the building is scheduled for mid-2022. The investment amounts to a total of around EUR 37 million.


The Kaufmannshof is being built directly on the port basin on a plot of land measuring around 5,600 m² as part of the development of the Zollhafen Mainz district. The building has a total of 50 high-end flats and around 3,100 m² of rental office space.

An architectural competition for the building was already held in 2017. The design by Meck Architekten together with the landscape planners Latz + Partner emerged as the winner. The building encloses a green inner courtyard and is surrounded by canals. These are large water basins in which an independent ecosystem with fish and plants is being created. Wooden decks make it possible to experience this special open space and invite you to linger a while. The building’s architecture is characterised by a clinker façade, reminiscent of the history of the Mainz customs port.

The residential and office building consists of four separately accessible building sections. Different types of homes are possible in 2- to 4-room flats, spacious lofts and townhouses, each with its own entrance and garden. In addition, there will be micro-flats for students or singles. Flexible solutions for modern working are being realised in the office part of the building. The standard floor with approx. 700 m² rental space can be individually divided, and water is supplied via loggias and a spacious roof terrace. The building also has an underground car park with 76 parking spaces and is pre-fitted for e-charging stations. There are also 45 bicycle parking spaces in the basement, 60 more are available above ground.

Construction work on a further 90 or so apartments in the “Flößerhof” project on the adjacent construction site is scheduled to begin in 2021. CA Immo and UBM Development are also implementing this development project in a joint venture.
