rotterdam’s ‘timmerhuis’ — the new home for the city’s municipal offices — has officially opened to the public. conceived by OMA, the scheme accommodates a range of retail, cultural, work and residential spaces, with the design led by partner reinier de graaf alongside associates katrien van dijk and alex de jong.

 

‘we are very proud of timmerhuis,’ states de graaf. ‘rather than adding to rotterdam’s crowded history of revisionist planning and cacophony of architectural styles, the typical mass of timmerhuis negotiates between the architectures of the buildings surrounding it.’

the building’s repeated units gradually step back from the street as they rise into two irregular peaks, creating a complex geometric form. meanwhile, an innovative structural system generates maximum efficiency and versatility both in terms of construction and in program. units can be added or even dismounted from the structure as demands on the building change over time, and can adapt to either office space or residential parameters as desired. additionally, green terraces on higher levels provide the possibility of an apartment with a garden in the heart of urban rotterdam.

the axis between the existing town hall and the post office coincides with the axis of symmetry of the timmerhuis, and the street between these two buildings continues into a passageway to the haagseveer,’ explains OMA. ‘the timmerhuis integrates with the neighboring stadtimmerhuis by maintaining the same floor heights, while the plinth height of 20 meters conforms to the character of the surrounding laurenskwartier.’

as the design brief stipulated that the timmerhuis must be the most sustainable building in the netherlands, OMA designed two large atria that act as lungs. these atria are connected to a climate system, while the building’s glazed façade uses hi-tech translucent insulation that allows for unprecedented levels of energy efficiency.
