We have been supporting the listed Kontorhaus since 2023. In addition to supporting the owner in the implementation of construction measures, we also assist the marketing and estate agency team in letting the vacant rental space.

Refurbishment of a listed staircase in Hamburg city centre. Restoration in accordance with historical finds and coordination with the heritage office. Among other refurbishings, the existing natural stone and terrazzo flooring was carefully restored and supplemented.

The entrance doors to the rental units were redesigned in accordance with the design elements of the time of construction and installed in the historically correct position. This was done while observing and implementing modern fire protection requirements.

Together with the redesigned lighting, the stairwell has now shone in new splendour since autumn 2022.

‍

The approx. 1200 sqm 2nd floor of the Kontorhaus in Hamburg's city centre was completely modernised, first and foremost to eliminate existing fire protection issues, which are not uncommon in historic buildings.

In the course of this, the space was completely cored and the floor plan reverted closely to the historical layout with wide areas.

The new layout of the future rental space was developed in a direct dialogue with the future users, taking into account the historical substance. The conversion and design were carried out in close consultation with the heritage office. In the course of the remodelling, previously concealed historical elements were discovered, secured and renovated as part of the construction work.

‍

The office space on the ground floor was combined with a storage area that was no longer in use. The layout of the new office space was optimised for the new user and extensively refurbished.

The historical structure and stylistic elements were restored and emphasised in the course of the conversion.

The Area of 480 m² was completed in spring 2023.

Conversion of the office space of approx. 400 m², completion in November 2023. To optimise the layout of the space, the area was completely cored to enable an optimal redistribution of the space. The space was fitted with new ventilation and cooling systems.

A three-storey retail space, connected by internal escalators, was reorganised. The floors were separated for the new uses.

The previously decommissioned "Kunsttreppenhaus" was put back into operation for access. This also includes the recommissioning of the listed glass lift.

The area on the 1st floor was remodelled into high-quality office space. In close consultation with the future user and the tenant's advisors, the space was completed and handed over to the tenant in 2023.

‍

The 1200 m² office space in Hafencity was redesigned and reorganised for the purposes of a notary's office.

An ultra-modern conference area equipped with the latest media technology, soundproofing, cooling and ventilation, a beautifully designed office area for the partners and lawyers, a lounge and an inviting reception area with a view over Hafencity complete this fit-out.

The new lighting concept for the building was implemented in collaboration with a lighting designer and the owner. The staircase was also improved, enabling better orientation thanks to new railings with integrated lighting and new basic lighting for the passageway. The result is an intuitive and inviting entrance to the building.

‍

The beautiful roof terrace of the Coffee Plaza was largely unused as there was no opportunity to relax. We supported the client in redesigning the roof space and created a refuge for the building's tenants with the help of new furniture and a new lighting system.
