As cities grow up and out, we are applying our skills to thinking about how urban environments could be better managed through the spaces beneath them.  From flood storage to urban transport, retail spaces to public places, we are thinking deep about the urban future of the UK and asking others to do the same.


  • To promote an awareness of the value of underground assets and to create a policy framework that can enable their fair use. 

  • To inform and guide the general public, decision makers, politicians and professionals how the use of urban underground space can create better cities with socio-economic benefits for society.

  • To encourage thinking deeply when making decisions and planning for the future of our cities.


  • Promote the importance of sustainable and compatible use of urban underground space and enhance awareness of the value it can generate for cities

  • Create a three-dimensional spatial planning strategy and define processes for safeguarding spaces underground

  • To be a facilitator bringing together interested organisations and individuals with a singular campaigning voice

  • To improve plans for future underground infrastructure and help coordinate a multi-disciplinary approach.

  • Develop guidance and best practice
