Children's Cancer Centre building work

Basement slab break out and look ahead to January 2026

Thank you for your ongoing patience between October and December as the breakout of the basement slab took place. As the slab was ground bearing, Sisk had to use heavy equipment to “peck” it into pieces and then remove the chunks away.

There are some small sections of slab and obstructions remaining that will be removed in January 2026.

The underpinning of the Paul O’Gorman Building will continue until the end of February 2026.

A large coring rig, like the one which was onsite over the summer will return in January 2026. This will drill through any final obstructions on site. Once these are removed, the piling rig will come to site in around March to create the basement wall along the north side of the site.

Information for children, young people and their families and carers coming to GOSH

We hope this Q and A provides you with some information about what to expect when you come to GOSH as we build the Children's Cancer Centre. We are very grateful for your patience as the works take place. Please don't hesitate to get in touch if you have other questions or would like more information - you can email the CCC team: ccc@gosh.nhs.uk or contact our PALS team.

Clinical services will remain open throughout the construction of the Children's Cancer Centre. Care and treatment for our patients will continue as normal.

We are working closely with our contractor, Sisk, to limit the noise and other disruption from the works on the hospital as far as possible by:

  • having acoustic screens around works areas to reduce noise and using water to dampen down dust.
  • having monitors in place to ensure that noise, vibration and air quality limits are not exceeded. There are also quiet periods between 7 and 8am, 12 and 1pm and 5-6pm.
  • limiting vehicles coming to site each day.

The construction team is working closely with our clinical teams to minimise any impact on patients and families but at times there may be noise or vibrations caused by the works. We understand this can be unsettling and we are grateful for your understanding as we build our new facility.

If you or your child are sensitive to loud sounds, you may wish to bring ear defenders or noise-cancelling headphones to your appointment. If the construction work is disturbing you, please speak to your ward team—they’re here to help.

Yes. Limits are in place for both noise and vibrations, and these are carefully monitored by the hospital and construction team to ensure they stay within safe levels.

Your clinical team is always available to support you. You can also contact the Patient Advice and Liaison Service (PALS), who can help answer any questions or raise concerns on your behalf.

Changes that will be in place for the duration of the construction works

The main entrance on Great Ormond Street has closed. For most people coming to Great Ormond Street Hospital, the best alternative entrance is on Guilford Street.

Appointment letters and My GOSH will also let you know which entrance is best for you to use.

Patient pick-up and drop-off location is now on Guilford Street near the Morgan Stanley Clinical Building entrance. The Great Ormond Street entrance will be closed for the duration of the building works. Please do not use the entrance on Powis Place as this is for emergency ambulance access and staff only.

Find out more about the best ways to travel to GOSH.

Find out which entrance is best for you.

Great Ormond Street is now one-way (from Lambs Conduit Street to Queen Square). Cyclists will continue to be able to go both ways along all of the street. Access for emergency ambulances will continue to be permitted from Queen Square to Powis Place.

Information for local residents

If you live near Great Ormond Street Hospital, our GOSH community website provides information about the project and how the construction process will be managed to limit the impact on our neighbours.

How to get involved

Pick up your copy of "The Look Inside" magazine. It has been developed so children and young people can find out more about our Children's Cancer Centre and how it is being built and the difference it will make for everyone at GOSH. If you cant wait until you are next here, please email ccc@gosh.nhs.uk so we can send you a copy directly.

Children's magazine opened on a construction site colouring page, on a blue tablecloth. There are some construction-related stickers on that page and we can spot the hands of a child holding the stickers sheet.

We would like to invite patients and their families to co-design the Children's Cancer Centre (CCC).

Kate, a children's nurse, is asking for current and former oncology parents to join the Parent Advisory Group to help develop the CCC.

The Parent Advisory Group meet virtually on Fridays from 12pm to 1pm once a month in a friendly and supportive environment to discuss what is happening with the centre and ask parents for their valuable suggestions.

You can email CCC.PPI@gosh.nhs.uk with your contact information and Kate will get in touch. Please inform them of any additional needs you may have to facilitate your involvement.

You can also register for updates by emailing CCC.PPI@gosh.nhs.uk
