BRISBANE'S ever-changing skyline faces transformation with a fresh push to relax CBD height restrictions.
Lord Mayor Graham Quirk has written to Federal Transport and Infrastructure Minister Anthony Albanese requesting a review of the current 274m height cap on city skyscrapers, as the 2014 Brisbane Airport Masterplan - which includes the parallel runway project - is finalised.
The changes could result in buildings of 300m or taller climbing into the city skyline, in a move Brisbane City Council believes could earn the city hundreds of millions of dollars.
But it could increase costs for the airport and airlines.
The current 274m cap for Brisbane exists to limit interference with flight instruments and aircraft navigation.
Brisbane's tallest approved building is Mary St's yet-to-be-constructed 274m 111+222 project. Billbergia's initial proposal for a 297m structure was refused due to height restrictions.
The Courier-Mail revealed in January, the developers of what will soon be Brisbane's tallest residential tower, Herschel St's Meriton Infinity project, had applied to temporarily operate a crane at 311m during construction of the well-advanced 262m tower.
Cr Quirk said current restrictions limited growth and business opportunities and increasing CBD heights to 300m could add an extra six levels and more than $620 million in economic value in terms of future development.
A 350m limit could result in an extra 20 levels and more than $2 billion in economic value, according to BCC.

"Brisbane's CBD is projected to grow rapidly over the next 20 years however the current cap on building heights will potentially limit floor space and curtail economic activity," said Cr Quirk.
"A vibrant city centre is fundamental to the success of Brisbane's economy and culture and has complementary benefits to the airport."
Cr Quirk said a report by Strategic Airspace found building heights of 300m could be possible by revising current take-off gradients at the airport from 3.3 per cent to 4 per cent resulting in higher fuel costs.
There is also potential for a further $1 million per annum increase in fuel costs if the runway approach is altered.
The report also found raising building heights to 350m could be possible by relocating runway navigational aids at a cost of between $1 to 2 million.
"I am advised that the changes required to increase CBD building heights do not diminish safety or service regularity," said Cr Quirk. "The efficiency of airport operations may be impacted but those costs would be far outweighed by the potential opportunities for increases in CBD-based economic activity."
The 2012-2031 Brisbane Economic Development Plan estimates the CBD and nearby suburbs could accommodate an additional 130,000 jobs over the next 20 years. BCC's City Centre Masterplan forecasts the CBD will need an extra 50 buildings to meet growth projections.
