St Mary’s is the major urgent and specialist hospital for north west London

St Mary’s is the major acute and specialist hospital for north west London.

The need for redevelopment

St Mary’s is the site in most urgent need of redevelopment:

  • The cost of fixing all of the St Mary’s 'high risk' backlog maintenance – the building issues at most risk of causing major problems – is £224m. This represents a third of the 'high risk' backlog maintenance liability for the whole of the NHS in England.
  • Our poor estate is increasingly causing significant operational problems – recent examples include a ward ceiling falling down and a flood in our surgical innovation centre. The latest estimate is that, without investment, we have 7-10 years before there is an almost certain likelihood of a ‘catastrophic’ estate failure meaning we would have to close services.
  • Much of the site is very old - a quarter was built pre-1948.
  • Our average bed occupancy at St Mary’s is 94 per cent – at peak times it is now over 100 per cent. There is no more room within the existing site to add capacity.

Outline proposals

We’re proposing to build a completely new St Mary’s Hospital.

The Trust is working closely with Imperial Health Charity, who own part of the St Mary’s land earmarked for wider development, as well as Imperial College London, the Trust’s research and education partner.

As we gear up a programme of ongoing engagement with our stakeholders, we have put forward an initial vision for the hospital:

  • To be the major acute and specialist hospital for west and north west London – able to respond flexibly to future health need, threats and opportunities
  • To act as a key hub for north west London’s integrated care offer
  • To continue our legacy of research, innovation, safe and high quality care.
  • To set new gold standards for patient and staff experience, community partnership – a genuine anchor institute - and sustainability
  • To be a building that our community can be proud of.

In terms of the redevelopment approach, we have been clear we want to:

  • Use the value in our land – and Imperial Health Charity’s - to help fund the new hospital, ensuring optimal balance of the size the hospital and other developments
  • Ensure the hospital remains fully operational throughout the rebuild
  • Maximise the investment already made in design and planning for our new ‘triangle’ building

And, in terms of design, the building must be:

  • Designed from the ‘inside out’ – form will follow function
  • User-led – through early and on-going involvement with staff, patients and local residents
  • Provide a welcoming and healing environment – use of natural daylight, space for nature, acoustics, materials, art, lighting
  • Adaptable – responding to changes in clinical practice, technology and expectations
  • Sustainable – net zero carbon

The 'triangle building'

During the summer of 2016, we brought forward a proposal for a first phase of redevelopment for St Mary’s Hospital – a brand new, eight-storey building on the eastern part of the estate on the current location of Salton House, the Dumbell and the Victoria and Albert buildings.

In January 2018, we were granted planning permission following our application to Westminster City Council for what is now often referred to as the ‘triangle building’. Since then, we have needed to explore a more holistic approach to the redevelopment of all of our estate, which has resulted in our current redevelopment approach.

Within our current redevelopment approach, we continue to see the triangle building as a practical first phase of redevelopment – of St Mary’s and our wider estate.

Outline timetable

Until we have secured initial business case approvals, the timetable will remain tentative:

  • July 2020 – launch our initial staff, patient and public involvement activities
  • August - submit our 'strategic outline business case' to NHS England, Department of Health and Soclal Care and HM Treasury
  • July/August – clinical feasibility review
  • September – procurement process for permanent design and planning teams and advisors
  • November – initial response on strategic outline business case
  • First half 2021 – further strategic outline case work for resubmission
  • Date to be decided – planning application
  • 2022 – planning and business case approvals completed
  • 2029/30 – a new St Mary’s built and fitted out.
