Widen By Sansiri

Widen By Sansiri is a 215-unit condominium under development on Nang Linchi Road in Bangkok's Sathorn district, built by Sansiri, one of Thailand's largest listed developers. The 34-storey tower sits on roughly two rai of land and is designed as a pet-friendly building, a differentiator in a district known for high-density, business-oriented towers. Unit sizes range from around 45 square metres for one-bedroom layouts up to roughly 210 square metres for the largest three-bedroom residences, with prices from 7.85 million to 39.1 million baht. Completion is scheduled for the fourth quarter of 2028. Sathorn is one of Bangkok's established embassy and financial districts, and Widen By Sansiri sits within a few kilometres of Central Rama 3, several of the city's longest-running private hospitals and a cluster of international schools. With only 215 units across the tower, Sansiri has positioned the project around exclusivity and low density rather than volume, aiming at buyers who want a central Sathorn address without the scale of the district's larger developments.

Widen By Sansiri is designed as a pet-friendly building, with a dedicated pet playground among its amenities alongside more conventional condominium facilities. The design brief favours natural materials and earth tones, aiming for a calmer, more residential feel than the glass-and-steel towers typical of Sathorn's business core.

Widen By Sansiri sits on Nang Linchi Road in Sathorn, one of Bangkok's established embassy, banking and expatriate districts. The immediate area mixes residential soi with grocers and small malls, while Central Rama 3 provides a larger shopping and cinema option a short drive away.

Healthcare access is a particular strength of the location, with BNH Hospital, Saint Louis Hospital and Bangkok Christian Hospital all within a few kilometres. Families have a choice of international schools nearby, including Shrewsbury International School and Saint Andrews International School's Sathorn campus. Sathorn's ongoing redevelopment, including the King Power Mahanakhon tower and the One Bangkok complex, continues to add office and retail floor space to the district.

• Pet-owning professionals who want a central Bangkok address with amenities built specifically around keeping animals.

• Expatriate families working in or near Sathorn's embassy and corporate district, within reach of the area's international schools.

• Downsizing buyers drawn to the low unit count and quieter positioning relative to Sathorn's larger towers.

• Off-plan investors comfortable with a 2028 completion date and the standard risks of buying ahead of construction.

Buyers wanting immediate occupancy, or the lowest entry price in the Sathorn condo market, will find better options elsewhere: this is a premium-positioned, low-density project rather than a budget one.

Prices at Widen By Sansiri range from 7.85 million to 39.1 million baht, with completion scheduled for the fourth quarter of 2028. Thai buyers can hold units freehold, and foreign buyers can purchase on a freehold basis up to the standard 49% foreign quota per project, with leasehold generally available for the remainder.

Sathorn has long been one of Bangkok's most established districts for both corporate tenants and expatriate rental demand, supported by its embassy cluster, hospitals and international schools.

Risks to weigh

• The project is off-plan with completion not due until late 2028, carrying standard construction and delivery timeline risk.

• With only 215 units, resale liquidity may depend more on individual unit appeal than on broad market volume.

• Sathorn's premium positioning means entry prices sit above many other Bangkok districts, which affects achievable rental yields relative to purchase price.
