The Timmerhuis in Rotterdam features a design that manages to simultaneously combine standardisation and variety. It is being referred to as a “mutable” building that will be able to adapt its shape over time as the function of the property changes. The idea behind the design is that buildings are constructed and then need to be renovated periodically when their purpose changes, resulting in large expenses in the future. A building that can mutate would make savings because a full renovation would never be needed, potentially making the property future-proof.

The Timmerhuis is a mixed use building that houses municipal offices, retail spaces, 84 apartments, and leisure spaces like a gallery and cafe. There is even parking beneath the property for residents and visitors to use. The building’s design has a pixelated effect which opens the possibility for new extensions to be added in numerous places in the future, seamlessly blending with the original structure.

When the design was unveiled there was concern over how such an innovative approach could be created within such a tight budget. This challenge was overcome thanks to prefabrication. By making aspects of the blocks in advance, including the steel framework, a great deal of the costs can be saved because of lower labour requirements. The standardisation also led to economies of scale for additional savings. When you look at the building it is impossible to tell that it was built on such a tight budget.

Sustainability was an important requirement for the design. This was accomplished in several ways, by using energy storage systems, solar panels and innovative window shades. The use of steel for the frame and lower use of concrete provided benefits as the metal is recyclable. The property was awarded an “excellent” rating by BREEAM, showing the green credentials of the design.

It will be interesting to see how attitudes towards the Timmerhuis change over time, particularly when the time comes to alter the building for a new purpose. It could certainly start a trend for conscientious, adaptable design that can be changed when necessary. The idea could be applied to commercial architecture, domestic properties and mixed use buildings like the one in Rotterdam.
