The Interlace has won the top prize at the 2015 World Architecture Festival held at Marina Bay Sands.
The residential property by OMA/Ole Scheeren, featuring 31 blocks of apartments stacked in a hexagonal arrangement, took home the World Building of the Year title at the annual event, considered the Oscars of the architectural world.
The 1,040-unit condominium by CapitaLand Singapore sits on an 8ha site and was completed in 2013.
German architect Ole Scheeren started the project when he was at Rotterdam-based firm OMA, but he left in 2010 and completed the housing project under his new practice, Buro Ole Scheeren.
The property came out tops after a live judging yesterday by a 'super jury', led by English architect Sir Peter Cook.
The Interlace project team had won in the Housing - Completed Buildings category of the festival, beating 13 others. It then went up against other winners of completed buildings in 17 categories, including mammoth projects such as the Sino-Ocean Taikoo Li Chengdu shopping complex and Qatar Faculty of Islamic Studies in Doha for the Building of the Year award.
There were 338 projects submitted this year.
This is not the first time Singapore has won the festival's top accolade - Gardens by the Bay won the prestigious title in 2012, when Singapore hosted the festival for the first time.
