The Sick Kids Friends Foundation will use the funds to create a welcoming entrance at the Royal Hospital for Sick Children in Edinburgh, new family-friendly environments and play spaces with a virtual aquarium. Work will start on the new hospital site later this year and the foundation will have input in both outdoor and indoor areas.
David Reith, chairman of the Sick Kids Friends Foundation, said: "We're extremely excited to announce that we can commit such a substantial fund to the re-provision of the RHSC in Edinburgh.
"Our plans bring together the needs and feedback of many valuable stakeholders to ensure our support is positioned where it is needed most.
"We're deeply grateful to all of our donors whose generous support and trust has helped us pledge such a fantastic sum to the new facility. I hope fundraisers will continue to help us raise the funds required to further enhance this marvellous hospital which will care for generations of sick children from across Scotland."
