Current design

The current design of the station was completed in 1986. The Station is divided in a South and a North entrance, were on the South side a station building is constructed.
The building is placed under an angle in relation to the rail lines and kept separate from the tracks. Inside the concrete framework all the elements are placed to service the station in its operation and accessibility for the passengers.
All service elements are placed in red boxes which are hung from the concrete frame. Together with the yellow lines, showing roof edgings and pedestrian bridge a reference is made towards “ de Stijl”, also known as neoplasticism,  a Dutch artistic movement founded in 1917.

The North entrance is placed at the same angle as the south building in relation to the tracks. The north entrance contains a staircase only, with a concrete wall in the middle making a strong reference to the concrete frame of the South building.

Both North and South entrances are connected by a tunnel, providing a connection for pedestrians and cyclists only. The passengers waiting areas on both platforms are places in line with the tunnel and by doing so the waiting areas are visual directly linked.

Present functionality

IIn the current situation the ticket office has been closed for many years and the facility spaces on the ground floor has lost its purpose. Over time the amounts of travellers have increased to such a level which has led to the requirement of increasing the capacity of the stairs by enlarging them in width to 4 meters.

The outcome of flow studies at the station shows the highest passengers flow taking place through the tunnel from both South direction and North direction. The result of the increase of stair width needs to be reflected in the width of pedestrian walkway in the tunnel. The pavement connecting both staircases needs to be widened to 4 meter as well in order to maintain a good passengers flow between the North and South side.

Within the current context lifts need to be added on both sides of the station to allow disabled and ambulant passengers gaining access to the platforms and trains. The lift will at the same time provide vertical access for the Ambulance services to enable them to transport a patient on a stretcher by lift.   

The wish to entertain a shop in the South building is strongly present and this idea is taking into the design development.

The vision

The starting point of the design is to respect the existing architecture and to develop the new brief into the existing building by maintaining the character and if possible to enhance the current concept of the building. The main consideration to take this approach is to keep the building as a recognisable landmark building with which travellers have identified themselves with over the years.

The new additions to the building, being a 4 meter wide staircase and a lift on both South and North side of the station, to be kept as open as possible.
By placing these new elements the opportunity arises to open up the existing building and to bring more natural daylight into the building and onto the public route passengers take to access the platforms. To achieve this, the concept of a roof above the staircase was removed; the balustrade is changed into a structural glass balustrade with stainless steel handrails attached to the glass.
The lift is constructed out of a light steel framework to support all requirements needed for the lift to operate and is clad in planar structural clear glass system.

The position of the first flight of stairs has been changed from its original position as a response to the high increase of passenger’s flow coming from the tunnel.

The staircase is orientated directly towards the tunnel by placing it orthogonally which provides a better direct access to the staircase and fits best into the existing building by allowing the maximum amount of natural daylight to penetrate through.
The lift shaft is placed against the staircase to anchor the lift and the lift can function as a centre point for staircase users going up and down the staircase.

The use of planar structural glass as a cladding material provides the opportunity to allow as much natural light to pass through the shaft and this provides in the meantime a interesting shading patter in the building of the structural elements of the lift shaft. The dynamics of the lift car travelling up and down brings a extra level of dynamic to the scenery of the travellers.
The lifts are becoming a point of orientation and recognition because of its outstanding character to help identify the points of vertical circulation within the station. This is further enhanced by placing a red transparent film between the planes of glass at the top of the lift shaft which makes a direct visual connection to the existing red boxes in the south building.

To improve the quality of the tunnel, the east wall of the tunnel has been placed under an angle to open the visibility towards the horizontal circulation. The chamfered wall is to avoid blind spots in the traveller’s walkway and to bring the maximum amount of natural daylight into the tunnel.
