Sinochem Hong Kong Investment has sold 968 square feet of office space on the 15th floor of Nine Queen's Road Central for what is believed to be a record $19,000 a square foot, according to Treasure Land Realty Consultancy.
The identity of the buyer is not known.
Graham Wong Chi-keung, Treasure Land's director of commercial agency, said Sinochem also sold yesterday a 970 sq ft office at $18,800 a square foot.
Sinochem bought the 15th floor, which measures 13,720 sq ft, for $240 million, or $17,500 a square foot.
The highest price previously achieved for office space in Central was $18,200 for space on the 30th floor of the same building, Mr Wong said.
He believed Central office prices would continue to rise after the Lunar New Year break because of a shortage of space for sale.
