Hoyts is seeking extended operating hours as part of its plans for the Cronulla cinema complex.
A development application (DA) has been lodged for upgrade works costing an estimated $5.53 million.
The DA also seeks extended operating hours, from 9am to 1am seven days a week, except for 12pm to 11pm on Good Friday and Anzac Day.
No works are proposed to the elements of the building identified as having heritage significance.
The only changes to the exterior will be new signage and replacement of doors at the northern and western entrances.
Proposed internal works include full refurbishment of the six theatres to accommodate new seats and associated platforms, new speakers and upgrade to projection systems, new floor and wall finishes.
The foyer will have self serve food and drinks facilities offer as well as a new bar/cafe located on the northern side of the space.
No changes are proposed to the door and window arrangement along the northern facade, except as required to meet regulations.
The proposed low level bar will be designed to maintain transparency with outside.
Refurbishment of amenities will be carried out to meet current codes including renewal of fixtures, fittings and finishes and incorporation of ambulant facilities.
Refurbishment of the two smaller theatres will include demolition of the rear wall of the cinema, construction of new platforms over existing platforms to accommodate new seats and new floor and wall finishes and associated lighting.
"The building was substantially demolished during redevelopment works circa 1998," the DA said.
"Other than the western facade and its windows, which were reinstated, there are limited elements of heritage significance within the interior of the existing complex."
The DA said the proposed internal refurbishment of the complex would provide the community with an upgraded cinema experience.
"No major refurbishment works to the interiors of this site have been completed since the significant demolition and reconstruction works of 1998," the document said.
The DA said records held by the NSW Department of Planning, Industry and Environment revealed "the interiors of the building underwent dramatic degeneration and destructive alteration during the 1970s and 1980s following the closure of the original 1400 seat theatre in 1974".
