Diller Scofidio + Renfro's winning design for the new Hungarian Museum of Transport

Using the role of ground transportation as an organizing principle, the proposal “de-familiarizes ground — an often overlooked, everyday surface — by excavating, lifting, and cutting this plane to produce immersive and unexpected environments,” DS+R says.

One of the main elements of DS+R's redesign is the new Forecourt, a communal “place of decompression” that will be a “mosaic” of paved and landscaped areas including outdoor galleries, picnic area, shady bosques, a cafe, playground, and outdoor community spaces of the Törekvés Cultural Center. The Forecourt will also include a part of the museum's collection of transport artifacts, like locomotives and carriages that once traveled across the fields and streets of Hungary.

The ground level has galleries, storage spaces for large vehicle, as well as intermittent access from below, which allow for rare undercarriage views, the firm says. “Double height spaces slice through the ground, exposing subsurface infrastructure.” This layered environment continues throughout the scheme. A hovering mezzanine offers overhead views of exhibition and access to the museum's collection storage. Special galleries, educational spaces, and a museum cafe (with views of the surrounding cityscape) are all located on the “floating ‘second ground’” above the Gallery Hall roof.

Another distinctive element of DS+R's design is how the new Gallery Hall fuses with the historic Diesel Hall, which was built between 1958-62 and comprises of nine parallel naves that are each 110 meters long. The naves will be adapted for exhibiting and storing the museum's large items like railway wagons, tramway cars, buses, and other vehicles. The new Gallery Hall will be “slid halfway into the Diesel Hall, projecting into the Forecourt to increase needed space and provide reinforcement for the Diesel Hall structure.”
