GSK Stockmann advises Adler Group on the sale of the Holsten Quartier project in Hamburg

GSK Stockmann provided the Adler Group with legal advice on the sale of the “Holsten Quartier” development in the centre of Hamburg’s Altona district. The project, which covers an area of around 87,000 sqm, was sold to a consortium of Hamburg-based companies consisting of Quantum and HanseMerkur Grundvermögen, in cooperation with SAGA.

Thanks to its unique scale and location in Hamburg, the Holsten Quartier is one of the north German city’s most high-profile projects. The Adler Group views this transaction as a stepping stone towards dedicating more attention to, and further developing, its residential rental portfolio in Berlin.

Located in the heart of Hamburg’s Altona district, the site is set to be transformed into a vibrant urban neighbourhood, with parts of the historic architecture being preserved and incorporated into the new design. Upon completion, which is expected from 2030 onwards, the project will offer approximately 2,000 flats for more than 5,000 residents.

The transaction is expected to be completed in the first quarter of 2026.
