Thonglor Soi 20 (Soi Chaem Chan) — Condos, Stays & Food
By Joe Thonglor — Thonglor neighborhood writer & fact-checker · · Last updated:
Thonglor Soi 20 draws around 1,300 searches a month, but search it and you mostly get rental and condo listings — because Soi 20 is a mostly-residential soi, and it has a second name people find confusing: Soi Chaem Chan.
This page covers the rest: the soi’s second name, its main condos and housing, and the beauty and food venues, all checked one by one on Google Maps on 18 July 2026 (our team lives in Thonglor — how we verify).
Where Thonglor Soi 20 is
Khlong Tan Nuea, Watthana, Bangkok 10110, per what Google Maps currently shows.
Soi 20 runs off Thonglor Road (Sukhumvit 55) on the even-numbered side. It’s a fairly deep soi that cuts through toward Ekkamai — it was once part of the Bangkok Design Week walking route in the Thonglor-Ekkamai zone.
⚠️ Why this soi is also called “Soi Chaem Chan”
This is why researching this soi gets confusing — Thonglor Soi 20 and Soi Chaem Chan are the same street. Some people even ask whether Thonglor “has a Soi 20” at all.
| Name used | Who uses it |
|---|---|
| Thonglor Soi 20 | The numbered-soi system along Thonglor Road |
| Soi Chaem Chan | The older local name, still used in venue and condo addresses (Cheesecake House, DLV Thonglor 20, CHAEMCHAND Clinic) |
What that means in practice: some addresses give only “Soi Chaem Chan” with no number 20 at all. If a driver looks blank, give both Thonglor 20 and Chaem Chan. It’s the same pattern as Thonglor Soi 25, which is also called Soi Saeng Ngoen.
Getting to Thonglor Soi 20
| From | How | Notes |
|---|---|---|
| BTS Thonglor | Exit 3 → motorbike taxi or red songthaew | Soi 20 is deep into the road — walking isn’t realistic |
| Ekkamai side | Soi 20 cuts through toward Ekkamai | Useful if you’re coming from Ekkamai |
| Red songthaew | Runs the length of Thonglor Road; get off at the Soi 20 mouth | Cheaper than a motorbike taxi but you wait |

Housing and condos on Thonglor Soi 20
If you searched “Thonglor Soi 20” because you’re looking for somewhere to live, this is the part you want — the soi (Soi Chaem Chan) is better known for housing than for food, from condos to buy or rent through to daily/monthly apartments:

Built on a “Green Cliff” concept with staggered triangular balconies planted with real trees; units run from 1-bedroom 30–41 sqm and 1-bedroom-plus 41–52 sqm to 2-bedroom 41–62 sqm. Reviews praise the leafy, resort-like common areas; about 2 km from BTS Thonglor · official site — Chewathai
- DLV Thonglor 20 (18 Thonglor Soi 20) — a condominium, rated 4.5 from 33 reviews, developed by Dalvey Development — the other condo option on the soi
- Apartments and daily/monthly rentals — beyond the condos, Soi Chaem Chan has several apartments and serviced apartments for rent (searchable on sites like Renthub and Hipflat), good for a short-term or monthly Thonglor stay off the main road

Who it suits
Thonglor Soi 20 works well if you:
- Are looking for somewhere to live in Thonglor and want a quieter address off the main road, from rentals to newer condos
- Want a highly-rated lash or nail salon like Corny Beauty
- Want a late-night option at the soi mouth (24-hour Bonchon)
Maybe not for you if: you want a strollable street full of venues or a community mall — try Thonglor Soi 15 (Market Place) or Thonglor Soi 11, which are denser with venues.
