Together with Schilderscholte Architects, the office building of Van der Spek Vianen and apart of the warehouse have been completely renovated.

"The renovation of this business premises from the 70s promises to be the most sustainable office building designed by our office. The sophisticated design shows how an existing structure can make optimum use of the possibilities available. The design was started from the end user , user-centered design is combined with a low-tech approach to the energy issue.The ventilation is natural and is driven by a solar chimney, the flat roof is optimally used for solar energy collection, the street façade receives strikingly shaped slats that last direct sunlight blocks throughout the year ".
The existing steel of the main structure consists of portals and floor disks. These has been kept intact as much as possible. Added are a steel plate concrete floor at a height of approx. 3 m, roof constructions, beautiful steel stairs and a built-in elevator.
A part of the new office is in split level. An Atrium has been added to the rear and solar panels have been installed on the roof. The existing Durox concrete plate roof has been stiffened to support the added load of the solar panels.
The facade has been completely replaced and the slats have been placed for this. The slats on the front are very slim and examined for vibration behavior.
A moss sedum roof has been installed above the warehouse. To make as few structural changes as possible, this has been achieved by replacing the existing roof with a much lighter SAB steel sheet roof.
