Great Ormond Street Hospital is a centre of excellence in the treatment of sick children, the training of doctors and nurses, and research into childhood illness which benefits many more children than the 90,000 who are treated here each year.

However, Great Ormond Street Hospital Children's Charity (GOSHCC) faces a major challenge as it fundraises to bring the hospital's facilities up to 21st century standards. We need to provide care in a more comfortable and convenient way, reduce unnecessary stays in hospital and provide better facilities for the one thousand parents a week who need to sleep near their child.

To do this will require redevelopment of two thirds of the hospital site to provide the very best in healthcare. The first stages will cost £312 million and we need to raise £123 million of this through public generosity. Once this work is completed we will be able to treat 20 thousand more young patients. GOSHCC's first priority is raising funds for this essential work, however the charity must also continue to support the ongoing work of the hospital through buying vital up-to-date equipment, supporting pioneering research, and funding improved facilities to benefit families and staff.
