Malaysian property developer Mah Sing is selling land in Selangor to data center developer DayOne.

In a stock exchange announcement, the company announced this week that its wholly owned subsidiary, Southville City Sdn Bhd (SVCSB), sold land in Daerah Sepang, a district south of Kuala Lumpur.

SVCSB this week entered into a conditional Sale and Purchase Agreement (SPA) with WG Malaysia X Sdn Bhd for the sale of 78.80 acres of freehold land located in Southville City township, Mukim Dengkil.

The deal was for a total cash consideration of RM617.8 million ($152.8m). The land is currently vacant, and the buyer intends to develop it into a data center. The deal is set to close in the second half of 2027.

Selangor, a western state on Peninsular Malaysia, contains the Klang Valley, which is Malaysia's second-largest data center market by capacity and its colocation hub.

WG Malaysia X Sdn Bhd is a subsidiary of DayOne Data Hub II Sdn Bhd.

Founded as a plastics manufacturer in the 1960s, Mah Sing ventured into property development in 1994. The company has 58 projects across more than 5,300 acres, spanning residential, township, office, retail, and industrial developments.

Bridge DC was previously set to develop a data center on Mah Sing-owned land in Southville City, but backed out.

APAC-focused DayOne was spun out of Chinese data center firm GDS back in 2025. The company's portfolio currently comprises more than 500MW of data center capacity in service and under construction, and more than 500MW held for future development across sites in Hong Kong, Singapore, Malaysia (Johor), Indonesia (Batam), and Japan (Tokyo).

The company recently broke ground on a site in Thailand and another in Singapore. In August, it made its first foray into markets beyond Asia, announcing a campus in Lahti, Finland.

DayOne acquired 65 acres of land in Johor from Malaysian property group Paragon Globe earlier this year.
