Sutherland Sharks Football Club has received development approval for a new, two-storey club building at Seymour Shaw Stadium.
The club says the modern, new facilities will cater for enormous growth in the code in shire, including participation by girls and women.
Sutherland Shire Council approved the development application (DA) for the $1.4 million project.
On the ground floor will be a gymnasium, home and away change rooms, toilets, canteen and cafeteria space.
The first floor will include two club rooms and administrative office space, kitchen with associated kitchenette, toilets and storage space.
"The [proposal] does not involve any works beyond the boundaries of the subject site, nor will the proposal facilitate any use that will give rise to negative amenity impacts upon adjoining residential properties," the DA stated.
A business case prepared by the club in 2017 said the changes were required to accommodate the service changes occurring with football over the past decade at local, state, national and international football programs.
"In the past fifteen years, changes in world, national, state and local football have had a direct and indirect impact on the SSFC operations," the document stated.
"An increased volume of players has arrived due to population growth in the Sutherland LGA.
"Women and girl's participation has increased tenfold over the past two decades."
The business case said, in 2007, when Seymour Shaw Stadium became the first east coast synthetic pitch in Australia, the club benefited enormously.
