Exploring and reinventing
underground urban spaces

To meet developing needs and uses, and bolstered by our expertise in the design of underground car parks, Indigo group offer a new vision of parking of the future that also includes more generally underground spaces. Taking a new approach that incorporates the needs of today and anticipating coming changes, it seems only natural to expand the possibilities that underground areas can offer: how they can be further integrated into urban life, how to offer users more mobility and services, and how to facilitate urban logistics and supply sustainable cities.


The parking of tomorrow will be open to its environment and at the heart of the mobility and service challenges for the Smart Cities of the future.

Sébastien FRAISSE,

President of the Executive Board


The Carpark of tomorrow must be integrated in the urban fabric to facilitate mobility in the larger sense, from services to energy.

Dominique Perrault,

Architect & urbanist, founder of DPA

A reflection in partnership with Dominique Perrault Architecture, specialist in underground architectures.
To lead these reflections, Indigo decided to work with a strong partner, a specialist in underground architecture, Dominique Perrault and his firm of international architects, DPA. The inventor of the “groundscape” concept and founder in 2013 of the SubLab for designing and reinventing the cities of tomorrow, some of DPA’s most exemplary developments that incorporate and invest in underground spaces include the National Library of France (BnF) in Paris and the EWHA Women’s University in Seoul, Korea.

These focuses are both global and local and lead to reflection on a number of possibilities that go beyond the subjects of mobility and parking; in addition to accommodating vehicles, car parks will become a centre of services entirely interconnected with their environment, acting as an extension of the city above: bringing in light, negating the “above-below” gap, connecting parking and transport, offering vehicle services and even becoming a source of energy.

Studying on site
typologies and cities

Underground carparks allow to intensify urban activities while protecting the integrity of the city fabric, including for the most sensitive heritage sites. Many of the most precious city centres of Europe have already been saved through the introduction of underground car parks in keys locations, Paris being one of the most exemplary cases.

DPA has identified 3 metropolitan conditions and 3 site typologies. Although they present different opportunities and require different architectural strategies, the general tendency is towards the development of a thick city floor that includes a variety of services relative to mobility at large, and also beyond: vehicle handling, passengers management, goods logistics, energy production as much as light industries and cultural venues.
