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.

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.
