3-bedroom apartment, 144 sqm / 1,550 sq ft, WIDEN by Sansiri, Sathorn
Main Characteristics
Apartment Description
The three-bedroom apartments at WIDEN by Sansiri, measuring 144 sqm (1,550 sq ft), are closer in scale to a private house than to a city residence. For buyers looking for apartments in Bangkok suitable for a large family, this format offers space that is becoming increasingly rare in new developments in Sathorn.
The layout is designed for comfort:
a covered terrace extending the living room
a living room and dining room for eight guests
an open-plan kitchen with an island
a master bedroom with a walk-in closet and en suite bathroom, featuring a bathtub and a separate shower
two bedrooms with built-in wardrobes, one with its own bathroom
three bathrooms with showers and a guest toilet
a utility room with a washing machine and a service yard
The apartments are located on the 21st floor, with floor-to-ceiling windows featuring Low-E glazing facing south-west, overlooking the green island of Bang Krachao and the Chao Phraya River. Ceiling height is 2.70 m, with Kohler and TOTO sanitary ware, TEKA appliances and a Kaadas electronic lock. Furniture, a washing machine, a Smart TV, curtains and textiles are included in the price.
There are few three-bedroom apartments at WIDEN by Sansiri, and diplomats and senior executives looking for this type of home in central Bangkok are a key target group. The limited supply helps preserve liquidity, both for rental and for resale, which is a strong argument for property investment.

Property Advantages
Terrace with river view
The open terrace extends the living room and looks out over the green island of Bang Krachao. Morning coffee and dinner with guests move outdoors into the fresh air
Three bathrooms and a guest toilet
The master bedroom has its own bathroom with a bathtub and shower, two further bathrooms serve the other bedrooms, and there is a separate toilet for guests. A family of five can live here without queuing for the bathroom
Space for two pets
The floor area of over 80 m² means the building rules allow two cats or two dogs. Many projects in central Bangkok ban pets, so apartments like these attract more tenants and buyers

About 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.
