PART of Southlands Hospital has been put on the market to public sector organisations.
They are being formally notified that the Harness Block is available for them to take on.
The formal notification follows the decision by the trust board in late April to declare the Harness block surplus to requirements.
From this point onwards, decisions about the future of the Harness Block will be determined in line with national rules for the disposal of public land.
Public sector organisations have until July 26 to submit a viable bid setting out the future use of the building and land.
The Harness Block would become available to private sector bidders only if no viable proposal is received within that time.
The Harness Block and peripheral buildings have now been placed on the government website which lists public assets available for sale.
All proceeds made from any future sale of the block will be reinvested into the hospital.
This development comes more than a year after the last trust in-patients were moved out of the block, to new wards in Worthing Hospital.
The rest of the site – the majority of the land – is still being retained by Western Sussex Hospitals NHS Trust.
