Commissioned by OVG re/developers and in consultation with the Port of Rotterdam Authority, JHK Architecten drew up an integral plan to restore and redevelop Cofely's entire former industrial estate on the Willingestraat on the Sluisjesdijk peninsula.
Cofely's new accommodation is the first phase of this redevelopment with an office building of ca 6,000 m² gross floor area on the River Maas and 134 parking spaces at street level. In a later phase there is still space for a second office building on the Robbenoordsehaven and a company hall on the Sluisjesdijk.
The new office building is a compact no-nonsense five-storey volume lifted into space, with the main entrance on the ground floor and space to park under the building. An important underlying principle in this design are the large floor surfaces of 1,000 m² per level, which can be freely organized and have a wonderful view over the Maas and the city of Rotterdam. As soon as you step out of the lift, the entirely glass façade on the Maas side provides a fantastic panorama over the water.
The offices are located on the first to fifth floors. A clear supporting structure and floor plan organization with all the workplaces at the façade provide the opportunity to create a pleasant working environment throughout the building and to make communicative and appealing meeting spaces or an archive or test area in the middle zone. On the fifth floor, a restaurant with kitchen is planned. The technical area is located on the roof, out of sight of the direct surroundings.
Around the building on its own site, various different types of paving and lighting have been implemented. For the design of the outside lay-out, the underlying principle was also to fit in with the sturdy no-nonsense work environment of the Rotterdam harbour and contribute to the coherence and social safety of the area.
With this project, OVG re/developers and Cofely had the ambition of realizing an office building with low energy consumption. As a result, the building form is based on a compact volume with broad floors and relatively little façade area and therefore little transmission loss through the façade. In the façade design, the percentage of glass depends on the orientation of the building in connection with the warming-up of the social areas. In addition, in collaboration with HdG and DGMR, an investigation was carried out and an integral provisional package of technical installation measures was compiled that includes the application of a TES installation, low-temperature underfloor heating and climate convectors.
