News just in that the 104-rai space on the corner of Wireless and Rama 4 roads that once housed the popular Suan Lum Night Bazaar is soon to become a new mixed-used space called "One Bangkok."

The Bangkok Post reports that the billionaire tycoon behind Chang beer, Charoen Sirivadhanabhakdi, is behind a deal valued at around B120 billion to convert the neighborhood into Thailand's biggest mixed-use development when it opens in 2021.

For perspective, the mixed-use real estate development which Dusit Thani recently announced on the other side of the street is worth B36.7 billion, while Thailand's tallest building, MahaNakhon, is worth around B20 billion. 

What we're trying to say is, One Bangkok will be on-another-level massive. The total area of land is almost one-third the size of Lumphini Park. Charoen has plans for five office towers, five luxury hotels, three residential towers, plus plenty of retail space, art and culture facilities. In total, it's expected to hold more than 60,000 people, with 50 rai of the area earmarked for green space. 

The wasteland which became of the Suan Lum Night Bazaar has been a big Bangkok talking point ever since the popular market closed down in 2011. Over the past year, it has been used to house a cut-price Chang-branded theme park in much the same way that Sukhumvit's Dinosaur Planet is space saving for the Mall Group's third installment for the EM District. 

The announcement of One Bangkok comes on the back of a spate of mega project announcements for downtown Bangkok which look set to transform the city center. Directly across the road, Dusit Thani hotel's partnership with Central Group looks set to reinvent Silom, while the old Silom Center building on the other side of the skywalk is also earmarked for a shopping center makeover. 

Further along Rama 4 towards Chamchuri Square, Samyan Mitr Town is a similarly ambitious project from Golden Land (Park Ventures Ecoplex, Sathorn Square), the property development arm of Charoen's TTC Group.
