Full-scale renovation of a multistorey dwelling in Aachen and the modernisation of residential and shop units.

As part of a modernisation programme, an existing classicist multistorey dwelling located within the inner city area of Aachen was due to undergo a transformation process: a previously unused gastronomy unit located on the ground and basement floors was to be converted into commercial units with retail space, and the storeys situated above were to be comprehensively renovated.


The entrance areas to the newly created shop units were designed both in compliance with planning specifications and with the barrier-free principle – when accessing the building both from Mefferdatisstrasse and Dahmengraben – thanks to the inclusion of new glass facades with zero threshold, automatic sliding doors.

By separating the rear building section of the new commercial unit on the ground floor, the use of one further, smaller shop unit could be achieved, which faces out towards Mefferdatisstrasse.

The existing ridge turret and courtyard roof were removed and replaced by overhead glass panes.

The former kitchen belonging to the gastronomy unit on the first floor was separated, deconstructed and then converted into an apartment.

The apartments situated above on storeys two and three were also completely renovated and modernised.

The former attic was deconstructed in parts, and the apartment was expanded into a gallery. The roof was also renovated for improved energy efficiency.
