Children's Cancer Centre building work
What's happening during Spring on the CCC site
Over the next three to four months (mid June - October 2026), the excavation of the basement of the CCC will take place.
The equivalent of around 200 double decker buses of earth will be removed and the deepest point will be 13.8 metres below ground level - this is equivalent to two and a half giraffes!
Diggers will be on site removing the earth and large tipper trucks will take this material away. There will be around 35 lorries coming to site each day.
This is a big increase in activity so please do take care on Great Ormond Street and Powis Place. Please remember, the public access to the hospital is via the Octav Botnar Wing and Morgan Stanley Clinical Building entrances.
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.
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.
