Sansiri’s announced tower on Sukhumvit Soi 51, in Thonglor, does something unusual on a busy street: 22 storeys holding only 11 homes. That low count, and a triangular building shaped by the plot itself, are the whole point of it. It sits on the Sukhumvit corridor, close to BTS Thonglor.
Checked 22 October 2026 against Sansiri’s own website and investor pages: Sansiri has still published no official name, tenure, price, home sizes or completion date for this tower, so the open questions below still stand.
- 11
- homes in the buildingAcross 22 storeys. Towers of several hundred homes are the norm on central Sukhumvit, so this is very low.
- 75
- parking spacesGenerous for eleven homes, which tells you what kind of buyer it is built for.
- Triangular
- the shape of the plotA design problem the architects turned into the building's identity rather than working around.
Why so few homes
Privacy bought through scarcity. Few neighbours, more space per floor, and a quieter arrival than a large tower allows.
On a street this busy, a building with almost nobody in it is how you get calm without leaving the centre.
Read the full explanation
Eleven homes across 22 storeys is very low for central Sukhumvit. The triangular land was a design problem, and the architects made it the building’s identity instead of working around it. That is the real argument for eleven homes rather than a hundred.
Thonglor, and who lives there
One of Sukhumvit’s most established high-end streets, and already built for daily life rather than waiting for it.
Getting around
BTS Thonglor, on the line, with the rest of central Bangkok a few stops either way.
Shops and eating
The Emporium, EmQuartier and Terminal 21, with The Commons and Gateway Ekkamai nearby.
Schools
Bangkok Prep, Wells International, The American School of Bangkok and Ekkamai International are all close.
Read the full explanation
Thonglor draws both Thai and international buyers, and everything a household needs day to day is already in place rather than promised. For families weighing a central base, the schools alongside the shops and the train are much of what keeps the street in demand.
What is not known yet
This is an early announcement and the images are marked as drafts. Four things a buyer decides on are not public.
- Whether it is freehold or leasehold.
- Price.
- The mix of home sizes.
- A completion date.
All four are worth confirming directly before relying on anything. If you are weighing this one, or comparing it against other low-density Sukhumvit buildings such as SLS Residences on Sukhumvit 24, we can talk you through it honestly and tell you whether it fits.
