WIDEN
Complex Characteristics
Residential Complex Description
Sathorn remains Bangkok's business core, home to embassies, international company offices and international schools. WIDEN by Sansiri is on Nang Linchi Road, in one of the district's greenest neighbourhoods. The project is being developed by Sansiri, one of Thailand's largest developers, and Japan's Tokyu Development.
What sets the project apart:
215 apartments in total in a 34-storey tower, a small-scale format for central Bangkok
227 parking spaces, more than there are units
units handed over fully furnished, with appliances
pets allowed, both cats and dogs, which is rare for central Bangkok
Layouts
1-bedroom: 45 sqm, from ฿9.2 million
2-bedroom: from 64 to 91 sqm
3-bedroom with terrace: 144 sqm
Signature Suite penthouses: from 187 to 210 sqm
Living at WIDEN
The ground floor features a park with a water cascade and a dog-walking area. The 30th floor is reserved for residents: a 25-metre swimming pool with an infinity edge and views over the Chao Phraya, a fitness centre, a sauna and a lounge. A rooftop garden completes the amenities. Nearby are Villa Market (100 m), Raintree School (450 m) and Synphaet Hospital (550 m).
Why buy now
Tenants from embassies and international companies tend to rent for longer and pay for quality.
All remaining available units are sold under the foreign quota on a Freehold basis.
A 30% deposit is paid on purchase, with the remaining 70% due only at handover in 2028.
The Sansiri name supports resale, and buying during construction fixes the price until the building is completed. For investment purposes, buying property in Bangkok on these terms can be worthwhile.

Developer
Sansiri is one of Thailand's largest and most established developers, whose projects can be confidently recommended to clients.
Sansiri Public Company Limited was founded in 1984 and has been among the country's leading developers for approximately 40 years. It is listed on the Thailand Stock Exchange (SET: SIRI), headquartered in Bangkok, and operates nationwide, developing condominiums, houses and townhouses.
Scale and figures
Founded: 1984.
Public status: SET listing since 1996.
Portfolio: hundreds of completed projects and tens of thousands of units; by the 2010s already 237 projects and over 60,000 properties across 9 provinces and one project in London.
2025: No. 1 in Thailand by number of new units launched — 1,847 units (approximately 12% of all launches in Bangkok and surrounding areas within the half-year period).
Plan for 2026: 30+ new projects with a combined value exceeding THB 50 billion, target sales of THB 48–53 billion, transfers of THB 39–46 billion.
Geography
Sansiri is particularly strong in:
Bangkok and its metropolitan area (urban condominiums and residential complexes).
Major tourist provinces (resort condominiums and complexes).
On Phuket, Sansiri is developing resort projects, one of which is RHEA by Sansiri in Cherng Talay, between Surin and Bang Tao beaches.
Developer approach and strengths
Sansiri positions itself as a full-service developer based on:
Property development — development of residential properties across different segments.
Property services — property management, brokerage, rental.
Hotel management and associated services.
Sansiri is one of few developers whose projects participate in official long-term investment and long-stay visa programmes for foreign buyers. Upon purchasing a condominium unit valued at THB 3 million and above and meeting immigration requirements, the owner gains the right to apply for an annual investor visa with renewal options, as well as to arrange residency status for family members.
In a number of pilot programmes launched on Phuket, Sansiri projects (including Rhea by Sansiri) are used as base properties for arranging such visas, and the developer, working with partners, assists owners with document preparation and submission.
Why we confidently recommend Sansiri to our clients
Nearly 40 years in the market and public status — transparent reporting, regular filings and investor oversight.
Strong track record — hundreds of completed projects, tens of thousands of handed-over units, leadership in number of launches and sales volume.
Experience in resort regions — not only Bangkok but major tourist destinations, including Phuket and projects such as RHEA by Sansiri.
Full range of services for owners — development, property management, rental and resident services, which is particularly important for foreign buyers.
Financial stability and growth plans — revenue exceeding $1.1 billion, profit around $170 million and dozens of new projects annually.
Through scale, experience and service quality, Sansiri logically belongs on the shortlist of developers that the agency can confidently recommend to clients considering property purchase in Thailand and Phuket.
