London Underground Station Design Idiom

London Underground has a rich design heritage stretching back over 150 years. It is a
defining part of what makes London a leading world city. Attention to detail has made its
customer environments world renowned, yet there remain inconsistencies in the quality of
its stations. In order to continue to innovate and inspire customers and staff, the London
Underground Station Design Idiom sets the future look and feel of all stations across the
Underground's vast and diverse network.
London Underground spent 18 months working with Studio Egret West to develop the Idiom.
The final document covers all of London Underground’s 270 stations, with guidelines for
how to create ordered, comfortable, accessible and atmospheric stations that are
integrated with commercial and community uses. It outlines a holistic approach that can be
practically applied to any style of station and any size of project, from small-scale
patch repairs to brand new stations.
