Lodged with Wollongong City Council by Prince Property Consulting, the development application seeks approval for "a new timber deck to the courtyard" and screening around the property.

The revamp aims to give the once-busy nightspot "a fresh new look" and would "better utilise the courtyard area overlooking Crown Street", according to the plans.

"The proposal will provide greater pedestrian amenity and contribute to the creation of a unique streetscape character in keeping with the commercial area," the plans say.

"The proposed [changes] will utilise innovative elements that will positively contribute to the streetscape of the locality."

The Glasshouse has been closed for much of 2014, and before that had significantly dropped from its former position as the late-night venue of choice for young revellers.

In 2009 it was the second most violent venue in NSW with 36 incidents listed on the Office of Liquor, Gaming and Racing's list of the state's most violent nightspots.

It is owned by Wollongong Nightlife (WNL), which owns most Wollongong nightclubs including Ivory, The Harp and The Grand.

The renaming and refurbishment of the Glasshouse comes after a boom in Wollongong's smaller bars and restaurants during the past two years, that has driven punters away from the old, cavernous, beer barn-style venues.

Photographs on the venue's new Mr Crown Facebook page, set up last month, show glimpses of the internal renovations, which include timber decking, disco balls and oversized black leather furniture.

Posts also indicate there is "more info coming soon".

The deck plans are on public exhibition through the council's website until January 23.
