Innovative and sustainable design wins competition for City Hall in Rotterdam 

Europe's modern architectural epicentre is soon to receive a new city hall, courtesy of the Office for Metropolitan Architecture (OMA), in collaboration with Werner Sobek and engineers ABT. Rotterdam's Stadskantoor, as the building will be known, will accommodate municipal services, offices, and residential units in the city. OMA's design was announced this morning (Wednesday) as the winner following a public consultation period and deliberation of an expert jury, which commented: “OMA’s design was the perfect combination of innovation and suitability for the surrounding context.”

Led by OMA partners Reinier de Graaf and Rem Koolhaas, the design was chosen from five submissions by Dutch architecture companies. OMA conceived a modular building with repeated units gradually set back from the street as they rise into two irregular peaks. The building’s composition of smaller cells creates an impressive, complex form when viewed from Coolsingel, one of Rotterdam’s main arteries, and allows for subtlety and adaptability as the Stadskantoor abuts the adjacent municipal building from the 1950s, the Stadstimmerhuis.

The Stadskantoor's innovative structural system is designed to generate maximum efficiency and versatility both in 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. Green terraces on higher levels provide the possibility of an apartment with a garden in the heart of urban Rotterdam.

The building's concept of flexibility – together with a climate regulated by warm air stored in summer and released in winter, and vice versa, and the use of hi-tech translucent insulation in the building's glass façade – allowed OMA to meet the design brief’s requirement of making the Stadskantoor the most sustainable building in the Netherlands, despite its construction of glass and steel. The embedding of nanogel in the facade is a key factor in providing lightweight insulation allowing the structure to maintain its form but maintain an ecological profile.

Reinier de Graaf commented: "Rather than posing as the city's next superlative, the design for the Stadskantoor is partly a building, partly an urban condition – a skyline in its own right. The design attempts to mediate between the adjacent town hall, post office and Stadstimmerhuis. Through an intentional ambiguity, the mass immerses itself in the city's diverse architectural periods, absorbing the scales and styles of its immediate context."

Set for completion in 2014
