Mah Sing Buys Kuala Lumpur Land Plot for Future Development, Continues Data Center Push in Malaysia

Mah Sing has acquired land fewer than 500 meters from Kuala Lumpur’s city center and hopes to roll out a premium offering later in 2026, Lionel Leong, Mah Sing’s deputy CEO, told Fortune. The move marks a departure from the firm’s M Series properties, which are priced at 500,000 Malaysian ringgit ($126,000) and target the mass market with affordable luxury homes.

Lionel Leong said the success is benefiting local firms. “The spillovers are quite natural,” he said. Leong pointed to a 150-acre site in Southville City, Selangor, which Mah Sing hopes to develop into a large-scale data center hub with proximity to key infrastructure, access to power, water, dark fiber connectivity and the potential to tap renewable energy solutions.

The zone was formally established in January 2025 to allow businesses to set up complementary operations on both sides of the causeway. Mah Sing has identified Johor Bahru as a key growth market due to its proximity to Singapore and rising cross-border economic activity.

In recent years the company has expanded beyond residential projects into data centers and industrial parks to tap Malaysia’s AI boom. The conglomerate ventured into the manufacturing of plastic gloves in response to the spike in demand for PPE during the COVID-19 pandemic. Lionel Leong said the firm’s long-term strategy centers on diversification.

“We’re looking to have a balanced and diversified business,” he said. Leong recalled visiting construction sites with his father in the 1990s, when Tan Sri Leong Hoy Kum first took an interest in real estate and would drive the family far from town.

Leong has noted that margins improved substantially after the shift into properties, allowing Mah Sing to leverage its entrepreneurial strengths while supporting Malaysia’s urbanization push.

Fortune reported that the firm is repositioning itself for the artificial intelligence era by leveraging land banks in the Klang Valley and Johor to court data center operators.
