The building

The building.

Sindhorn TONSON sits on Tonson, a quiet lane near Langsuan and Lumphini Park, one of several Siam Sindhorn addresses around the park's edge. Developed by Siam Sindhorn, it holds just 59 residences over 17 floors and was completed in 2018. The small scale is the point: low density, few neighbours, and a private feel close to the park.

The tenure is leasehold rather than freehold title, structured by the developer as a 30-year lease with a 30-year renewal option.

Read onClose

Embark confirms the exact lease terms for a given unit at inquiry.

With the building completed and only 59 homes in total, availability is limited and trades quietly between owners.

The neighbourhood

The neighbourhood.

Six streets, four sub-markets, and one 142-acre park they all answer to.

The parkLumphini Park is 142 acres in the middle of the city, and the corridor is named for it: the six streets around it are priced by how directly they face it.
The streetsWireless, Langsuan, Ratchadamri, Sarasin, Chidlom and Ploenchit, and Upper Sathorn. Each trades differently, and the corridor guide takes them one at a time.
What tradesThe densest cluster of freehold branded residences in Bangkok sits on this axis, on land where most sites are held on long lease.
