Services at three community hospitals could be moved to a health hub at Wexham Park Hospital in Slough to raise cash for a hospital trust which is £13million in debt.
St Mark's Hospital could see existing facilities reduced to a smaller 'footprint', meaning excess land could be sold.
A large public consultation will cover all the changes and is due to start in early autumn.
Plans have not yet been finalised but are being discussed by clinicians who will oversee the process.
The Shaping the Future consultation is jointly run by NHS Berkshire, Heatherwood and Wexham Park Hospitals NHS Foundation Trust, Berkshire Healthcare NHS Foundation Trust and clinical commissioning groups. It aims to introduce 'smarter ways of working and optimum use of buildings'.
The final options to be put out to consultation have not yet been decided.
At first the focus was based around Heatherwood Hospital in Ascot, but after one of the initial meetings last year the trusts went 'back to the drawing board' and started looking at all health services.
A report looking at how to make the hospital trust sustainable over the next three years was due to be submitted to strategic health authority on Friday.
