- A first strategic joint venture with Nomura Real Estate (Thailand), brings together the global strengths of both organizations to create a Pets Welcome luxury freehold condominium on a rare, private site in the heart of Sathon, Bangkok’s key CBD.
- THE MONUMENT, a legacy condominium brand of Sansiri, returns after a decade, guided by the “Monument of Nature and Heritage” concept and its three enduring values: nature, the heritage of Sathon Soi 10, and timeless design. Central to the project ethos is a 50-year-old pink trumpet tree, preserved as part of its living heritage.
- Project highlights include a rare offering of only two exclusive penthouses, each spanning up to 303 sq.m., alongside the debut of SANSIRI PAW & CO., setting a new design standard for living well with pets and meeting the everyday needs of modern pet parents.
Sansiri Public Company Limited (SET: SIRI), Thailand’s luxury real estate developer, has announced a landmark strategic partnership with Nomura Real Estate (Thailand), one of Japan’s major real estate developers, to unveil ‘THE MONUMENT SATHON’. The development marks the partners’ first joint venture, with a total project value of THB 4.5 billion (shareholdings of 55% by Sansiri and 45% by Nomura).
Positioned as a legacy-level luxury freehold condominium and a new landmark on Sathon Soi 10, in Bangkok’s prime CBD, the project reinforces Sansiri’s leadership in the luxury freehold condominium market and the trust it holds among global partners, built on more than 40 years of experience in Thailand’s real estate sector, as well as its expertise in design, development quality and after-sales service.
Mr. Uthai Uthaisangsuk, President of Sansiri Public Company Limited, said “Our first strategic joint venture with Nomura Real Estate (Thailand) marks an important step in bringing together the vision, strengths, expertise and experience of two organizations to develop a luxury freehold condominium project that meets international quality standards. Sansiri’s leadership in luxury residential development, combined with Nomura’s extensive property development know-how, will enable THE MONUMENT SATHON to meet the expectations of high-net-worth customers—both real demand residents and long-term investors—while delivering enduring value for today and into the future.”
Mr. Yasuhiro Hirano, Managing Director of Nomura Real Estate (Thailand) said “We have strong confidence in Sansiri as Thailand’s leading real estate developer, supported by its consistently strong business performance and its deeply informed approach to planning developments for high-net-worth customers. THE MONUMENT SATHON is among the most centrally located and highest-priced projects Nomura has participated in developing in Thailand. Drawing on nearly a decade of project-development experience in the country, together with our KAIZEN* approach to quality at every stage, we will work with Sansiri to raise project standards, broaden our shared business scope and drive sustained growth in the Thai market.”
Building on THE MONUMENT’s legacy of condominium success with THE MONUMENT SATHON – A Rare New Freehold Address on One of Sathon’s Most Coveted Land Plots
THE MONUMENT SATHON is Sansiri’s new Pets Welcome luxury freehold condominium, priced from THB 9.9–150 million and located on one of the rarest sites in the heart of Sathon. Marking the return of THE MONUMENT, Sansiri’s legacy condominium brand, after a decade, the 29-storey development comprises just 185 residences, ranging from 39 sq.m. one-bedroom units to only two exclusive penthouses spanning 240–303 sq.m.
The project offers more than 100% conventional parking, nearly one rai of green space, and comprehensive shared facilities designed for relaxation, wellness, work, families, children and pets. Located on Sathon Soi 10, at the heart of Bangkok’s prime CBD and financial district, it is only 80 metres from BTS Saint Louis Station, 500 metres from Silom Road and 1.7 kilometres from the Si Rat Expressway.
The development is surrounded by leading business and financial office towers, including Empire Tower, Sathorn Square, AIA Sathorn Tower, Park Silom and Central Park Offices; more than 10 key embassies, including the British, Australian, German and Singaporean embassies; leading private and international schools such as Bangkok Christian College and Assumption College; and world-class healthcare facilities including Saint Louis Hospital and BNH Hospital. Lifestyle destinations and acclaimed fine-dining restaurants—from King Power Mahanakhon, ICONSIAM and theCOMMONS Saladaeng to Maison Dunand, Le Du and Nahm—are also within easy reach.
Sathon remains one of Bangkok’s most distinctive CBD locations, where new supply is limited. High-net-worth buyers continue to prioritise luxury developments that stand apart through rare locations, design and a differentiated living experience—reflecting the enduring strength of this business district and its potential to preserve long-term value. THE MONUMENT SATHON builds on the success of the condominium brand’s two earlier developments: THE MONUMENT THONG LO, an iconic luxury freehold condominium in the heart of Thong Lo, and THE MONUMENT SANAMPAO, the series’ first project, which sold out in a remarkably short period.
Monument of Nature and Heritage — Design that Preserves Place and Nature
The concept reinterprets two defining qualities of Sathon: the nature that once formed the area’s foundation, and the neighbourhood’s heritage, shaped by its stories and way of life. From its original green landscape and waterways, Sathon has evolved into one of Bangkok’s most significant business districts. This evolution is expressed through architecture, landscape and interior design, with distinctive natural materials selected throughout. A more than 50-year-old pink trumpet tree at the project entrance will also be preserved as a living heritage—linking the site’s memories with its new chapter, while reflecting Sansiri’s approach to urban development that respects and protects the value of place.
Artisanship and Craftsmanship in Every Detail
The interior design brings together art and fine craftsmanship in every detail—from the thoughtful selection of materials and patterning techniques to iconic furniture, design objects and rare collectible pieces with rich design heritage and stories. Each element is carefully hand-picked and composed as an artful expression for living, creating a home that feels calm, private and timeless.
Introducing SANSIRI PAW & CO. — A New Standard for Pet–Human Lifestyle Communities
Debuting at THE MONUMENT SATHON, SANSIRI PAW & CO. is Sansiri’s first project under this concept designed for people and pets to live together seamlessly in everyday life. This pet–human lifestyle community connects indoor and outdoor spaces to support the needs and routines of both pet owners and their companions. Facilities include the Pet Sky Lounge for relaxing, working and spending time together; the Pet Sky Park for outdoor play and activities; and Pet Grooming & Spa for pet care and cleaning—all thoughtfully planned to ensure shared spaces remain comfortable for every resident.
