Turbot Nominees submitted a development application, care of Urbis, to Brisbane City Council on Thursday proposing a 30-storey office tower that would include, retail, a gym, conference and childcare facilities at 343 Albert Street.

The current tower has one of Brisbane City's most recognisable landmarks at its summit, a 10-metre digital clock.

The existing Suncorp Plaza was completed in 1971 and remained the city's tallest building until the construction of the AMP Centre in 1978.

The assessment report submitted to the council made no mention of a clock being included in the new tower design.

"The key rationale for the proposed development is the provision of a premium office grade building - a development typology underrepresented in the Brisbane market and currently in demand by tenants," the assessment report said.

"The proposed development has also been carefully designed to improve the interface and relationships with the adjoining Albert Street Uniting Church and Brisbane Dental School building opposite the site."

The report said only six other Brisbane buildings achieved the high standards of premium office space, including 111 Eagle Street, Riparian Plaza, Riverside Centre, 1 William Street, Waterfront Place and 480 Queen.

"Half of these buildings are recent builds and reflect the requirements that tenants are demanding in modern office buildings," it said.

The tower would have three basement levels with 165 car parks, 224 bike spaces and three short-term stay and drop-off parking spaces along Albert Street.

The assessment report said the proposed building had been designed to be an "iconic landmark" in Brisbane's CBD and King George Square and would have extensive use of glass and voids.

The clock was severely damaged during the 2014 Brisbane hail storm.

The council will now assess the development application.

Comment was sought from Urbis.
