St Mary’s Hospital has been treating patients and making healthcare breakthroughs since it first opened in 1845, but its sprawling patchwork of aging buildings are crumbling.

With the need for a new St Mary’s Hospital increasingly urgent, we now have the funding to undertake detailed design and planning work.

Our ambition is to build a new, taller hospital on a smaller footprint, located within the eastern part of the current site. This will allow us to:

  • organise services, research and staff facilities in a much better way
  • keep our existing facilities running while we build the new hospital
  • reshape the whole site with an overarching masterplan

We want to explore using the surplus land to expand the cluster of life and data sciences businesses that has been developing around the hospital. As well as supporting better health and care, this would boost economic growth and help attract additional investment in a new hospital.

We need a bigger, better St Mary’s to respond to the changing and growing health needs of our local population over the coming decades. And the need is increasingly urgent if we are to ensure our future in Paddington and avoid major building failures that put services at risk.

St Mary's redevelopment site

Have your say

We have launched the first phase of a public consultation on the new St Mary’s and wider site.

As we start the masterplanning process, we want to understand what matters most to you.

  • How do you use the area now?
  • What are the opportunities to be explored?
  • What issues might cause concern?
  • What would you like to see on the site?

In particular, we are consulting on:

  • the overall approach to delivering a new teaching and major trauma hospital on part of the existing site
  • emerging masterplan principles for the wider estate, including access and movement, public realm, heritage, sustainability and how the site connects to surrounding neighbourhoods
  • the role of research and life sciences on land released once services move into the new hospital.

Complete the survey online. The survey closes on 20 March 2026.
