The Inland Revenue IT Centre has been located in the Laan van Westenenk Complex in Apeldoorn since January 2001. The Government Buildings Agency awarded a commission to adapt and extend the existing complex to accommodate ca 400 employees and to set up a commercially secure production and computerization process.
The complex has three components: the production building in a central location (Centrum), connected via a walkway with the energy building (Zuid). In the North is the diagonally positioned office building (Noord). Both Noord and Centrum buildings were already constructed in 1993, together with a fully automated high-rise warehouse. This warehouse was carefully demolished and materials and constructions from this demolition were reused where possible.
The existing assembly hall was turned into a production and IT centre operating round-the-clock. The two processes are kept strictly separate. This is made possible by locating the production processes, such as printing and final processing, on the ground floor. On the first floor there are now four heavily secured computer areas, the IT centres. They are kept separate by means of striking technical shafts, painted in a signal red colour. Daylight reaches the ground floor via roof lights and glass tiled floors. An office shell has been designed around this floor, with open office landscapes on the long sides. Meeting rooms, archives, pantries and sanitary facilities have been included here as separate elements. On the north side are the traditional office spaces. The corridors around and between the computer rooms are raised so that building services and installations can be concealed underneath. As a result, the office landscape lies at a lower level.
On the south side, there is a functional energy building; a walkway carries all the installation cables to the Centrum. The energy building contains an innovative system of energy generators, necessary to ensure continuous operations. A great deal of research has been devoted to the sustainable generation of energy, where the company not only draws from traditional energy sources, but is also capable of storing and reusing self-produced energy.
The existing style of the complex has been taken into consideration as much as possible. The light grey-green metal siding shows the industrial character in a modest way and refers respectfully to the green and wooded surroundings. The site has been given a new lay-out and is now transparent with some greenery.
