roximity to mass transit systems has become a priority for Bangkok office tenants. There are two existing mass transit systems: the BTS sky train and the MRT subway, which serve primarily the central and midtown locations of Bangkok.
Office locations in Bangkok can be geographically classified into two main regions, which are:
1. Bangkok CBD (Central Business District)
Defined as the area incorporating Silom, Sathorn, Rama IV Road, Ploenchit, Wireless Road, Asoke, and the early Sukhumvit area (Sukhumvit Road up to the Asoke intersection).
2. Core CBD
The majority of Bangkok’s grade A office buildings and the headquarters of many multinational companies are located here, as well as embassies, 5-star hotels, and some of the city’s leading shopping centres. Several of the best residential districts are also located here. The area is served by both of Bangkok’s mass transit systems. The core CBD includes Silom, Sathorn, Wireless and Ratchadamri Road, passing through Rama IV and Ploenchit Road.
3. Outer CBD
This area covers the primarily residential areas of Bangkok along the BTS sky train route, specifically the early Sukhumvit area and Asoke.
There are a number of suburban and midtown office locations in Bangkok. These are popular with companies requiring convenient access to downtown as well the industrial areas and the airport.
The northern corridor, extending from Petchaburi Road to Lad Prao and Ratchayothin, has a range of office buildings. These tend to be located on the route of the subway along Ratchadapisek and along the BTS line running along Phaholyothin and Viphavadi-Rangsit, the main artery road to the north of the city. This area is home to headquarters of SCB Bank and is the preferred location for oil and gas companies centered around PTT's head office on Viphavadi-Rangsit Road.
Chaengwattana, in the nort of Bangkok, is a mjaor government administrative centre.
To the east of the city, close to Suvarnabhumi International Airport, is the Bangna-Trad district. This area not only provides good access to the airport but is also the gateway to the Eastern Seaboards, Thailand's industrial centre.
Petchaburi Road and Sukhumvit Road extend to the east of Bangkok, with the BTS running along Sukhumvit and the airport link running parallel to Petchaburi. Office locations along mass transit routes have become increasingly popular.
Rama III Road runs along the river, providing good road access to the city centre and easy connections to eastern Bangkok via the Industrial Ring Road. The Bus Rapid Transit (BRT) system will also run along this route.
