Sansiri’s announced tower on Sukhumvit Soi 51, in the Thonglor district, takes an unusual approach to a busy address: 22 storeys holding only 11 residences. The low count, and a triangular building shaped by the plot itself, are the project’s defining features. It sits on the Sukhumvit corridor, close to BTS Thonglor.
Eleven homes in a triangle
The headline is the count. Eleven residences across 22 storeys is very low for central Sukhumvit, where towers of several hundred units are the norm. The triangular shape of the land posed a design challenge, and the architects turned it into the building’s identity rather than working around it. For a buyer, the practical result is privacy held through scarcity: few neighbours, more space per floor, and a quieter arrival than a large tower allows. The project also includes 75 parking spaces, generous for the unit count.
Thonglor, and why density is the story
Thonglor is one of the Sukhumvit corridor’s most established high-end residential streets, drawing both Thai and international buyers. The everyday infrastructure is already in place: BTS Thonglor for transit, the Emporium, EmQuartier, and Terminal 21 for retail, and lifestyle anchors such as The Commons and Gateway Ekkamai nearby. In a location this busy, a low-density building is how a project offers calm without leaving the centre. That is the real argument for eleven homes rather than a hundred.
A location built for families
The area also sits close to several international schools, including Bangkok Prep, Wells International School, The American School of Bangkok, and Ekkamai International School. For families weighing a central base, that proximity, alongside the retail and transit, is part of what keeps Thonglor in demand.

Where it sits
At this stage the project is an early announcement, and the renders are marked as drafts. Tenure, pricing, the unit mix, and a completion date were not yet public, and all are worth confirming directly before relying on them. If you are weighing Sansiri’s Sukhumvit 51, or comparing it against other low-density Sukhumvit residences such as SLS Residences on Sukhumvit 24, we can talk you through it honestly and tell you whether it fits.
