Marzipanfabrik, Building No 11

Office building with underground car park and extension to the existing structure on the site of the marzipan factory

Construction of a new office building with an underground car park

Building 11, a new office building with an underground car park, was constructed on the site of the former marzipan factory. The building has a gross floor area of 6,500 m² and a gross volume of 26,800 m³. The office spaces were designed to allow for a variety of unit types and floor plans.

Connection to the existing building stock of the quarter

The new building was connected to existing parts of the quarter via a glass link. This connection integrates the new development into the existing building fabric of the former industrial site.

Addition of a storey to an existing building

In parallel with the new development, a factory building dating from the 1950s was extended by an additional storey. The extension was constructed using timber-frame construction and complements the existing building structure.

Facade and building concept

The building envelope consists of a combination of a clinker brick facade and a mullion-transom facade. The facade concept is complemented by aluminium windows as well as a staggered storey constructed from prefabricated timber elements. The facade design draws on the materials and structures of the existing quarter.

Exposed concrete construction

The structural work was carried out entirely to exposed concrete standard. The ‘Doka Framax Xlife plus’ formwork system was used to construct the exposed concrete walls, enabling a uniform formwork finish on the concrete surfaces. Around 550 m² of slab formwork was used for the slab construction.

The extended shell

PORR’s scope of work comprised the construction of the extended shell, as well as concrete works, façade structures and the structural preparation for the subsequent finishing trades.

Part of the Marzipanfabrik quarter development

Building 11 is an office block situated within the Marzipanfabrik quarter in Hamburg-Bahrenfeld. The project comprises 6,500 m² of gross floor area, 26,800 m³ of gross volume, an underground car park as well as the addition of extra storeys to an existing building dating from the 1950s.
