Customs House (Bangkok)

The old Customs House (Thai: ศุลกสถาน, RTGS: Sunlakasathan) is a historic building in Bangkok, located on the eastern bank of the Chao Phraya River in Bang Rak District.

Built in the Palladian style, it is a fine example of the prevalent use of Western architecture in public buildings during Siam (Thailand)'s modernisation under the reign of King Chulalongkorn (Rama V).

[1] The building sits on the eastern bank of the Chao Phraya River in Bang Rak District, on Soi Charoen Krung 36, and was symbolically considered the gateway to the country.

In 2005, real estate consortium Natural Park won a 30-year concession from the Treasury Department (which administers the building as state property) to renovate the site as an Aman Resorts hotel.

The residents finally moved out in early 2016,[2] and the Treasury Department confirmed in 2017 that the project would go ahead under the U City company, as Natural Park was now known following restructuring.
