Infinity Tower, Modern skyscraper in Brisbane, Australia

Infinity Tower is a 262-metre skyscraper at 43 Herschel Street in Brisbane's North Quarter, completed in 2014 with 81 levels and 549 serviced and residential apartments. Its structure is almost entirely reinforced concrete, and the vertical and horizontal streaks on its sides are aluminium facades designed to make the building appear taller than it is.

Meriton bought the former ground-level car park at 43 Herschel Street for A$25 million and excavation began in November 2009. Four storeys were added to the design, approved by Brisbane City Council, and in March 2012 Meriton sought federal permission for a crane reaching 311 m. Premier Campbell Newman and Meriton's Harry Triguboff opened the tower on 24 July 2013; levels 25 to 64 were completed from November 2013 and construction finished in early 2014.

The name Infinity Tower comes from its 81 stacked levels of serviced and residential apartments, 549 units in all. Meriton built it on the former ground-level carpark at 43 Herschel Street, and Queensland Premier Campbell Newman opened it with Meriton's Harry Triguboff on 24 July 2013. Residents share a spa, lap pool, private gym and sauna.

Infinity Tower stands at 43 Herschel Street in the Brisbane CBD's North Quarter, a short walk from Roma Street railway station, King George Square and the Queen Street Mall. The Kurilpa Bridge nearby leads across the river to South Bank Parklands and the Queensland Cultural Centre. The apartments are private residences, so visitors see the building from the street rather than inside.

The white aluminium strips on the facade are designed to make the tower appear taller than it is. The building's structure is made almost entirely of reinforced concrete, and it uses a Schindler Miconic 10 lift system.
