Mitsubishi Estate has announced a major partnership with Central Pattana for a massive new mixed-use development in the heart of Bangkok’s bustling Siam Square district.

Named “CEntRal ceNTrAL” for now, the 42-storey tower represents Mitsubishi Estate’s largest single investment in Thailand so far. The massive build will feature 141,000 square metres of gross building area spread over 42 floors above ground and five underground storeys. The total cost of the project is estimated at 11 billion Thai baht, which is roughly 53.9 billion yen.

Work on the skyscraper began in July 2024. Developers expect the complex to open in phases starting from 2027. It marks the second time the Japanese real estate giant has joined forces with Central Pattana, following their previous collaboration on the Central Village Outlet mall in 2019. This new property will take on the flagship “Central” brand name.

The site is located in Bangkok’s primary retail and trend capital. To make transit simple, the finished building will link directly to the Siam BTS Skytrain station on the Sukhumvit Line and the National Stadium station on the Silom Line.

Developers are designing the layout to attract local Gen Z crowds, trendy professionals, and international holidaymakers. The retail areas will focus on luxury labels, restaurants, and experiential services. Meanwhile, the office spaces will offer flexible layouts designed for modern work-life balance.

The upper levels will introduce the 25hours hotel brand to Thailand for the first time. According to the developers, the hotel is “making its Thailand debut at CEntRal ceNTrAL, bringing its signature concept that celebrates the local culture, people, and spirit of the neighborhood.”
