Thonglor and Ekkamai are two parallel residential sois in Bangkok’s Watthana (Vadhana) district, Sukhumvit Soi 55 and Soi 63, one BTS stop apart: Thonglor runs 2,248 metres north from Sukhumvit Road and is 25 metres wide, Ekkamai runs 2,524 metres and is 18 metres wide, according to the Vadhana District Office.
Buyers often treat them as one place with two names. They are not. Of the buildings on our site, the Thonglor ones are finished towers, several close to the station, and the Ekkamai ones are a low-rise building and a row of houses; Ekkamai also has large condominium towers, and more are coming. Which soi suits you comes down to the kind of home you want and how far up the soi you are willing to live.

The two sois, side by side
Both run north from Sukhumvit Road towards Khlong Saen Saep canal, each with a BTS station at its mouth. The table sets out what a resident lives next to.
| Thonglor | Ekkamai | |
|---|---|---|
| The soi | Sukhumvit 55, 2,248 m long, 25 m wide | Sukhumvit 63, 2,524 m long, 18 m wide |
| At the mouth | BTS Thong Lo | BTS Ekkamai, beside the Eastern (Ekkamai) Bus Terminal |
| On the soi | Camillian Hospital, 423 Sukhumvit 55 | Ekamai International School, Ekamai 12 |
| School nearest the station | Wells International, Thonglor kindergarten: 1.4 km by road, 0.4 km in a straight line | St Andrews Bangkok High School: 1.2 km by road, 0.3 km in a straight line |
| Footpath | 2 m wide, 2,304 m from the mouth to the canal | 1.5 to 2 m wide, 2,500 m from the mouth |
Source: Vadhana District Office, roads and footpaths, read on 4 November 2026; the hospital and the school, their own sites; the schools, our schools guide. Donki Mall Thonglor, despite its name, has its address on Sukhumvit 63, and its operator puts it a 15-minute walk from both stations: the two sois are closer than their names suggest.
Who each one suits
These describe the buildings on our site, not every building on each soi. A buyer can find an exception on either.
Thonglor, if you want the station at your door
The towers near Sukhumvit Road, such as The Strand Thonglor at the junction and SCOPE Thonglor beside the station, put the BTS a short walk away. The soi is the wider of the two, at 25 metres.
Thonglor, if you want a finished tower
All 7 of our Thonglor buildings are finished and can be viewed today, from a small building of full-floor homes to large towers.
Ekkamai, if you want low-rise or a house
Our two Ekkamai buildings are small: Eden Ekkamai, 17 homes on Ekkamai Soi 12, and The Residenti Ekkamai, a row of houses on Soi Sukhumvit 65 with a lane through to Ekkamai Soi 10.
Ekkamai, if the school run is to St Andrews
St Andrews Bangkok's High School is 1.2 km by road from BTS Ekkamai (0.3 km in a straight line), and Ekamai International School is on Ekamai 12.
The schools, measured
Our schools guide measured the distance from each station to the international schools families ask about. The five nearest by road:
| School | From BTS Thong Lo, km | From BTS Ekkamai, km |
|---|---|---|
| St Andrews Bangkok, High School | 1.9 (1.2) | 1.2 (0.3) |
| Wells, Thonglor kindergarten | 1.4 (0.4) | 1.6 (1.2) |
| Wells, On Nut | 3.8 (3.7) | 3.1 (2.8) |
| Bangkok Prep | 3.9 (2.7) | 3.2 (1.9) |
| Anglo Singapore, Campus 31 | 3.8 (2.4) | 4.0 (3.2) |

The buildings on each soi
Embark Estate advises buyers on all 9 of these, on each soi or at its mouth on Sukhumvit Road. Each name opens the building’s own page, with its facts and what is available. The buildings near BTS Thong Lo on Sukhumvit 57 and across Sukhumvit Road are in our Sukhumvit guide.

Can a foreigner buy on either soi?
A condominium: yes, in your own name
As long as the building's foreign quota, 49 per cent of the total floor area of all its units, has room, and the purchase money is brought into Thailand from abroad. Ask for the current quota position before you commit.
A house: ask first
A foreigner generally cannot own land in Thailand. The Residenti Ekkamai's developer has not said which ownership structure it offers a foreign buyer, so ask before you plan around one.
What foreigners can and cannot own explains the rules; this is general information, not legal advice. For corridor prices, the Embark Bangkok Price Index covers Sukhumvit as a whole.
