Look at buildings vying to stand out across Singapore's business district skyline and "one" stands out. Make that several "ones".
Many of the buildings feature the number "one" in their names.
Consider these ones: condominium One Shenton (completed last year), waterfront dining and entertainment complex One Fullerton (2000), the office buildings One Marina Boulevard (2004), One Raffles Quay (2006), One George Street (2004), One Raffles Place (new name - 2008) and One Raffles Link (2000).
So why is one the one that is numero uno downtown? The number exudes the image of being top of the pack, says CapitaCommercial Trust Management, a spokesman for One George Street.
SundayLife! also did a quick check of buildings across Singapore with "one" in the name and found dozens including commercial building Surbana One (the former HDB Centre) in Jalan Bukit Merah and industrial building Focus One in Ubi View.
There is also 29-storey condominium Newton One in 1 Newton Road, which, says its owner, developer Lippo Realty, was named for its single tower and also because it is the Indonesian company's first residential development here.
Some "number one" buildings used to go by different names.
One Raffles Place was formerly OUB Centre, built in the 1980s. But in 2008, owner OUB Centre Ltd renamed it One Raffles Place amid a $540million plan to add a 38-storey tower office building and redevelop its retail podium.
The owner says it wanted to reflect the prime address in the commercial epicentre and to provide a strong identity.
Tenants have been won over, including GMP Recruitment Services, which moved into the building in 2004. The firm's assistant director of corporate services, Mr Josh Goh, 38, says being associated with a premium address helps to "beef up" the brand and add an "air of reputability".
However, there is one problem: The new name confuses clients and taxi drivers who get mixed up with all the buildings in the area with "one" in their names. Mr Goh says: "To overcome this, we refer to the previous name, OUB Centre, which immediately dispels any doubts."
Financial consultant Cheyne Chen, 24, who works in the CBD, says: "I am familiar with the buildings here but there is a chance that those who just started working here or those who need to go from one building to another might be confused."
