The air was crisp and the smell of mulled wine wafted through the buildings, while people milled and mingled.
At Swire Properties' 40th anniversary street party in Quarry Bay, streets usually filled with office workers were filled with revellers taking in jazz, a capella and dance performances and checking out booths for face-painting, art-viewing, eating, drinking and just being merry.
The event in Tong Chong Street, while celebrating a company anniversary, also sought to give something back to the community that had allowed Swire to flourish, donating proceeds to Operation Santa Claus and Habitat for Humanity.
This year's OSC donations will help children, the elderly, victims of domestic violence and those with mental and physical disabilities.
"I want my daughter to take care of the community. I don't want her to watch TV all day," said Andy Wong, a 15-year employee at Swire Properties who volunteers regularly with others in the company.
He, his wife and his eight-year-old daughter all volunteered their Saturday afternoon alongside other Swire workers to make the street fair happen, bringing in public donations through a pay-what-you-wish system. Other colleagues, like 24-year-old Karl Chan Man-ho, trained for hours to put on a variety dance show for passers-by.
Raffle tickets and limited-edition T-shirts designed by artist Tania Willis were on sale and 10 per cent of sales from the food and beverage stalls will go to the two charities.
Swire Properties is well on the way to raising a total of at least HK$500,000 for Operation Santa Claus, which is run by the South China Morning Post and RTHK. All public and corporate donations at the event and from the company's employees will be matched dollar for dollar by Swire Properties.
At the end of the day, even employees of rival developers came in for the party and had a kind word to say.
"It's important to do something local, not just big names," said Henry Fong, a 29-year-old marketing and retail specialist at Hutchison Whampoa's A.S. Watson. "Hong Kong people tend to keep their eyes on things happening in the world, but not locally. It's great that [Swire Properties] is supporting local and small charities."
