Deák Ferenc tér station is a distinguished hub of the Budapest metro network: three metro lines (M1, M2, M3) intersect here. To facilitate orientation, the new architectural concept makes the space understandable as a graph of nodes and connecting linear spaces. Static spaces (entrance halls, distribution and waiting areas) are characterised by neutral shapes and richly detailed textures, while dynamic spaces (pedestrian routes and escalator shafts) are characterised by dynamic shapes and brightly coloured cladding.

The renewed image with its transparency, bright and cheerful colours and attractive surfaces reinterprets the original retro architecture and also promotes public transport for all. At the -2 level of the underground complex a vestibule represents the entrance of the station. The free-floating individual luminaires create an imaginative plane under the false ceiling made of gleaming expanded aluminium sheets. At the platform Portuguese artist João Rodrigues Vieira's 1996 letter tiles were carefully restored, the artwork stands out in its moderate setting.

The section of the interlinking corridors was reshaped: the cladding unites the two tunnels into one, this new abstract form evokes the space-age of the construction. With additional mining a new elevator was constructed that serves as an accessible and secondary entrance.
