Construction on the 14-storey Paediatric Services Building at The Children’s Hospital Westmead has begun, which will house the largest critical care unit for kids in Australia.

The project team marked the milestone with a sod turning at the site of the new $619 million Stage 2 redevelopment.

The project will future-proof health care in Western Sydney and help staff treat, care and support children and their families from across the state and around the country.

The Stage 2 redevelopment is part of almost $8 billion in health infrastructure delivered or underway by the NSW Government across Western and South Western Sydney.

The capacity of almost every service will be expanded in the new building, which will form the biggest paediatric facility in NSW.

The Paediatric and the Neonatal Intensive Care Units will be increased in size and importantly, parents and carers will be able to stay with their children and babies when they need them most.

Featuring the most advanced technology, this new health facility will house the largest paediatric critical care unit in the country.

Patients, families, staff and community have been involved at every stage of the planning for this major redevelopment.

The new paediatric services building has been designed to ensure the facilities support both patient wellbeing, their carers comfort and deliver the best working environment for staff to deliver exceptional care.

The project would support around 1,100 direct jobs for Western Sydney, with the potential for supporting thousands of indirect jobs over the life of the project.

The redevelopment also includes a multi-storey car park; more access to redeveloped green spaces; improved spaces for families, and new and accessible playgrounds.

Construction is expected to be completed in 2025.
