The newly-completed $20 million Quakers Hill Nursing Home will open with a community open day on Saturday, March 1.
Residents can take a look around the centre in Hambledon Road and enjoy some family entertainment from 10am-2pm.
The event will include a free sausage sizzle, live music, jumping castle, animal farm and face painting for children.
The Alzheimers Australia Memory van will help raise awareness about the importance of brain health and dementia risk reduction.
An invitation only event for special guests will be held on Friday, February 28.
The former nursing home was destroyed in a fire that eventually claimed the lives of 11 residents in 2011.
Nurse Roger Dean pleaded guilty in the NSW Supreme Court to 11 murders relating to the fire and is now serving a life sentence.
Domain Principal Group managing director Gary Barnier said anyone thinking about aged care for themselves or their loved ones was welcome to the open day.
The new centre is three times the size of the previous one and can accommodate 127 residents.
It has 79 single and 24 companion rooms and also has a dedicated specialist wing for 16 residents living with dementia.
There are a range of accommodation options with warm decor and natural light and a beautiful, tranquil garden.
Parking for the open day is available at Mihkelson Reserve (access via Maslin Crescent) and the Quakers Hill Anglican Church (access via Morrell Crescent which is off Bali Drive).
Guests are not permitted to park in the Aldi car park or on Hambledon Road.
