Rare Freehold, Heritage-Inspired Design and Elevated Living for Bangkok’s HNWIs

Sansiri has officially launched presales for THE MONUMENT SATHON, marking the return of its prestigious THE MONUMENT luxury condominium brand after a decade. Positioned as a new-generation Legacy residence in the heart of Bangkok, the project brings together a rare freehold location, timeless design, craftsmanship and wellness-led living, targeting high-net-worth individuals (HNWIs) seeking both an exceptional home and long-term asset value.

Located on Sathon Soi 10, just approximately 80 metres from BTS Saint Louis, THE MONUMENT SATHON is valued at THB 4.5 billion and is being developed through a joint venture between Sansiri and Nomura Real Estate Group. Presales will run from 12 September to 30 November 2026.

The 29-storey development comprises just 185 residences, with prices ranging from THB 9.9 million to THB 150 million, from approximately 39 sq.m. one-bedroom residences to two exclusive penthouses measuring 240–303 sq.m. The project also offers more than 100% conventional parking, together with nearly one rai of landscaped green space.

Sathon: From Financial District to Complete Living District

Sathon remains one of Bangkok’s most established core CBDs, bringing together the city’s financial, diplomatic, hospitality and lifestyle ecosystems in a single district.

As global financial centres continue to evolve from primarily business-oriented destinations into more complete residential neighbourhoods, Sathon is following a similar trajectory. Its established infrastructure, connectivity and concentration of premium amenities make it increasingly attractive not only as a workplace, but also as a place to live.

At the same time, limited new supply in the luxury residential segment adds another dimension of scarcity to the market, particularly for buyers seeking freehold properties in established central locations.

For THE MONUMENT SATHON, this combination of location, limited supply and enduring neighbourhood value forms the foundation of its positioning as a long-term legacy asset.

A Rare Freehold Address Designed to Endure

THE MONUMENT SATHON marks the return of the THE MONUMENT brand following THE MONUMENT SANAMPAO and THE MONUMENT THONG LO.

Rather than replicating previous developments, Sansiri has adapted the brand specifically to the character of Sathon, drawing on the area’s accumulated heritage and distinctive urban context.

According to Ongart Suwankul, Deputy Managing Director, Condominium Development Division, Sansiri Public Company Limited, scarcity is an important component of long-term value in the luxury residential market.

“For the luxury market, rarity is an integral part of long-term value. Sathon is one of Thailand’s most important central business districts, bringing together finance, diplomacy, healthcare, education, hospitality and lifestyle. With the exceptional potential of a location whose value has been built over decades, THE MONUMENT SATHON represents a rare freehold opportunity. We took time to identify a location with the right potential to develop the next chapter of THE MONUMENT brand, adapting it to Sathon rather than simply copying and pasting an existing concept.”

MONUMENT OF NATURE AND HERITAGE

The design philosophy of THE MONUMENT SATHON centres on “MONUMENT OF NATURE AND HERITAGE”, bringing together nature, heritage and timeless design.

At the heart of the project is a more than 50-year-old Pink Trumpet Tree (Tabebuia rosea) preserved at the entrance as a living heritage element. Rather than replacing what existed on the site, the development incorporates the tree as a meaningful connection between the property’s past and its future.

This philosophy extends throughout the architecture and landscape design, with natural materials, carefully selected finishes and craftsmanship creating an aesthetic intended to become increasingly meaningful over time.

The result is a residential environment where luxury is expressed not through excess, but through the preservation of character, attention to detail and the quality of elements designed to stand the test of time.

Luxury Designed Around Real Life

Beyond its address and architecture, THE MONUMENT SATHON is designed around the evolving lifestyle of today’s luxury homeowner, with a focus on well-being, family, work-life balance and pet-friendly living.

Residents will have access to a range of wellness and lifestyle facilities, including a Swimming Pool, Hydrotherapy Pool, Pilates Studio, Heat Therapy Sauna and Cold Therapy Shower, as well as a Private Dining Room and The Canopy.

The project also introduces SANSIRI PAW & CO. for the first time, expanding Sansiri’s approach to pet-inclusive living with dedicated facilities including a Pet Sky Lounge, Pet Sky Park and Pet Grooming & Spa.

The concept reflects a broader shift in luxury residential living, where wellness, personalisation and the relationship between people and their pets are increasingly considered integral to the definition of a premium home.

A New Approach to the Luxury Presales Experience

Sansiri is also introducing a more experiential approach to the presales journey, allowing prospective buyers to experience the character of Sathon before making a purchasing decision.

Through the THE MONUMENT SATHON Exclusive Experience, Sansiri has partnered with Kasnäsbkk, one of Sathon’s neighbourhood destinations, to bring elements of the project’s design philosophy into the context of the surrounding neighbourhood.

The collaboration extends beyond interiors and visual design to include hospitality and gastronomy. THE MONUMENT SATHON and Kasnäsbkk have jointly developed a selection of special dishes inspired by four key project principles: Nature, Heritage, Timelessness and Craftsmanship.

For invited guests attending the Exclusive Experience, the journey begins with “The Monumental Welcome Refreshments,” a specially created menu designed exclusively for the occasion.

Additional collaborative dishes will also be available to the public at Kasnäsbkk for a limited period from 12 September to 30 November 2026, giving visitors the opportunity to experience the collaboration beyond the project itself.

A Legacy Address for a New Generation

With only 185 residences, a rare freehold position on Sathon Soi 10, direct proximity to BTS Saint Louis and a design philosophy rooted in nature and heritage, THE MONUMENT SATHON represents Sansiri’s latest interpretation of legacy luxury in central Bangkok.

Rather than defining luxury solely through size or specification, the project places greater emphasis on rarity, enduring location value, craftsmanship, well-being and the quality of everyday living.

For a new generation of HNWIs, THE MONUMENT SATHON is positioned not simply as a luxury condominium, but as a residential asset designed to be lived in today and potentially passed on to the next generation.
