High Wycombe Train Station Multi-Storey Carpark

Melchor was awarded the design and construct project for the High Wycombe Train Station multi-storey car park.

The car park takes its design intent from the neighbouring High Wycombe Train Station (known as Forrestfield Station during planning), creating a cohesive and integrated appearance across the development.

One of the most prominent features of the car park is the screening along its façade. This screening ties in with the station’s folding roof forms, providing an aesthetically pleasing finish while also functioning as a wayfinding element to announce the car park and enhance visibility within the precinct.

To accommodate the large catchment area of the station, the three-level car park provides 1,200 car bays to meet parking demand. The layout has been designed for maximum efficiency, offering a clear and logical flow for both vehicular and pedestrian traffic, with no blind aisles. Open stairwells further enhance visibility and contribute to a safer structure.

The main structure consists of a concrete floor system, utilising precast concrete shell beams supporting prestressed hollowcore floor planks. The beams span the 7.2-metre orientation, with 400-millimetre-deep hollowcore planks spanning up to 17 metres. An 80-millimetre-thick cast in-situ topping slab ties the floor system together. On the top floor, a 100-millimetre-thick topping slab was adopted to allow transverse post-tension ducts to be installed centrally within the slab, aiding in achieving a watertight finish. The supporting columns consist of cast in-situ concrete on isolated pad footings.

In addition to the above works, Melchor also installed stormwater drainage, firewater systems, gravity drainage, lifts, and all electrical works, including fit-out, testing and commissioning. This was delivered as a full turnkey design and construct project for the client.
