Tonson One Residence stands on Soi Tonson, a quiet lane off Langsuan near Lumphini Park, developed by Asset Five Group. It is a low-density 29-floor tower with around 80 residences, completed in 2023. It is one of the newest freehold buildings on this stretch of the park-axis, where most land is leasehold.
The building is freehold, which means outright ownership that passes to heirs rather than a lease that has to be renewed. That tenure is comparatively scarce on the park-axis. Foreign buyers can hold freehold units within the foreign quota, which Thai law sets at 49 percent of a building's total saleable floor area, and Embark confirms a unit's quota status at inquiry.
