The interchange upgrade aimed to improve pedestrian and cyclist access and transfer between, bus, London Underground and rail. This was achieved by the inclusion of direct access from the bus interchange to the underground station removing street-level passenger/vehicular conflicts, improved pedestrian crossings and walkways. Congestion was also reduced by a redesign of bus access routes, removing them from the gyratory system.

Sustainability was a significant consideration in the bus station design, the roof incorporating two cantilevered arms covered in 168 technologically advanced solar panels, enabling the interchange to produce a third of its own electricity.

The result is a striking contemporary structure, which formed the focal point of an extensive regeneration programme for the area. The twin arms extending from the bus interchange create a prominent local environmental feature and project a positive image for public transport.

Interchange is compact with short movements required between modes. Movement spaces are generally clear and uncluttered with information and street furniture situated away from desire lines. A good staff presence, visible CCTV and an operations room situated prominently within the bus interchange achieve a good sense of security.

Connectivity between the Underground station and the local area is good via a series of underpasses that avoid the need for at-grade crossings.

Information displays in the bus interchange include useful features such as clocks at each stand. Stands are clearly identified and include a display panel with service information and local area maps.

Issues include access for cyclists which can still be difficult, and pedestrian connectivity between the bus interchange and the local area via at-grade crossings that are not always located on desire lines resulting in more circuitous routes.
