Sansiri is confident that THE MONUMENT SATHON will generate sales of more than THB 1 billion, building on the company’s strong momentum in international markets. During the first half of 2026, Sansiri achieved more than THB 5.5 billion in sales from foreign buyers, surpassing its original target.

Strengthening Global Partnerships Following THB 5.5 Billion in International Sales
The appointment further builds on the successful partnership between Sansiri and Thaiway Property in marketing premium and affordable condominium developments to international buyers.
During the first half of 2026, Thaiway Property generated more than THB 2.1 billion in sales across a portfolio of Sansiri projects, including VIA 61, XT 10 Ekkamai, LOVE Charoen Nakhon, WIDEN by Sansiri, XELF by Sansiri and THE BASE Urban Rama 9.
The strong performance reflects continued confidence in Sansiri’s development capabilities, as well as the strength of Thaiway Property’s international sales network in reaching high-quality buyers, including investors, expatriates and overseas purchasers seeking premium real estate assets in high-potential locations.
The partnership now prepares to bring THE MONUMENT SATHON to international markets ahead of its presales launch in September.
Priya Bunnag, Chief Sales and International Business Development Officer, Sansiri, said:
“Today, the international market is no longer driven solely by the number of buyers. Growth is increasingly being led by high-quality purchasers who place importance on rare-location assets, trusted brands and long-term value preservation.”
“Our partnership with Thaiway Property represents another important step in expanding Sansiri’s strategic partnerships and connecting Thailand’s high-quality real estate developments with global networks. With more than 40 years of experience in Thailand’s property market, Sansiri brings strong expertise in product development, design, construction quality and after-sales services through PLUS Property. These strengths provide international buyers with confidence at every stage of ownership.”
“We are therefore well positioned to serve as a key gateway connecting global buyers with continued investment opportunities in Thailand’s real estate market.”
Sansiri’s international sales continued to demonstrate strong growth during the first half of 2026, exceeding expectations with sales of more than THB 5.5 billion. The company’s top three condominium projects among international buyers were Rhea by Sansiri, XT 10 Ekkamai and LOVE Charoen Nakhon, reflecting continued confidence among global buyers in the quality and long-term potential of Thai real estate—particularly luxury properties in Bangkok’s high-potential locations.
