INDUSTRIA, a real estate manager from Frankfurt and part of the Becken Group, has taken over the management of its rental housing project at Walter-Hallstein-Straße 13a-15b in Mainz-Weisenau. The project developer Ten Brinke had recently completed the ensemble with 103 apartments. On construction site 16 of the new Heiligkreuz-Viertel urban quarter, two buildings with around 8,000 square meters of rental space have been built. All of the two- to five-room apartments are barrier-free. They were built according to the energy-efficient KfW 40 QNG standard and with new construction subsidies from the state of Rhineland-Palatinate and are subject to rent and occupancy control. The rental will start in May 2026. The ensemble includes an underground car park with 86 parking spaces, a green outdoor area and a children's play area. The plans come from the Düsseldorf office POS4 Architekten.
The Heiligkreuz district is currently the most important housing development project in the state capital of Mainz. Since 2017, an attractive residential quarter with 2,000 residential units for around 6,000 residents has been under construction on an area of over 34 hectares on the former IBM site in the Weisenau district. The area has shopping facilities for daily needs and schools in the neighbourhood. It is conveniently located near a junction with the A 60 and about three kilometres from the city centre. A bus stop with a connection to Mainz main station is located a few minutes' walk from construction site 16.
INDUSTRIA acquired the property in 2023 as an asset manager for the open-ended real estate special fund "Wohnen Deutschland VII" as part of a forward deal. The fund is administered by INTREAL as a service KVG. The seller of the project is Ten Brinke. The company acted as both developer and general contractor for this property. The total investment costs amount to around 40 million euros.
Thomas Wirtz FRICS, Managing Director of INDUSTRIA, comments: "With the acquisition of the ensemble in Mainz-Weisenau, we are specifically expanding the fund portfolio to include further subsidised housing in a dynamically growing state capital. Ten Brinke's project combines sustainable construction quality, social housing supply and a very good micro-location – exactly the criteria that we consistently pursue for our fund."
Jens Wantia, Managing Director of Project Development at Ten Brinke, says: "With construction site 16 in the Heiligkreuz district, we have realised another residential project that combines high-quality architecture, functional floor plans and a high quality of stay. It was particularly important to us to create an attractive and liveable living environment, even under subsidy conditions. The combination of energy-efficient KfW 40 QNG standard, barrier-free apartments, well thought-out open space concepts and serial construction underlines our claim to develop sustainable and future-proof residential projects."
