Phrom Phong
In this building · The Waterford Diamond
The Waterford Diamond is a condominium project, developed by Waterford Property, located at Soi Santi Narueman, Khlong Tan, Khlong Toei, Bangkok. Construction of The Waterford Diamond was completed in 1998. The development comprises 1 building(s), with 46 floors and 538 units.
A late-1990s building with unusually large floor plans, The Waterford Diamond appeals to value buyers and long-stay families who want space near Phrom Phong without new-build pricing. Its older vintage means a lower entry price per square metre than newer Sukhumvit towers, which lifts gross yield even as capital growth is steadier than flashier launches.
Area gross yield: ≈4–5% · Resale price/sqm: ฿120,000–฿165,000 (indicative — confirm current figures before you buy)
Phrom Phong is the cosmopolitan, family-friendly heart of upper Sukhumvit, anchored by The Emporium and EmQuartier malls, Benchasiri Park and a deep bench of international schools and clinics. The Waterford Diamond sits just off the main road on a quieter soi, trading a few minutes' walk for calm.

Compare with The Emporio PlaceWhat residents praise: Space and price are what reviewers keep coming back to: genuine 1990s floor plans — one-beds around 55–60 sqm, three-beds over 130 — at rents well below newer Phrom Phong towers, plus a covered rooftop pool residents say is rarely crowded and parking that is generally available.
Common complaints: It is a late-1990s building and reviews say so: condition varies enormously unit to unit (original fixtures and full renovations sit side by side, so inspect the exact unit), older air-conditioning can struggle in hot season, and the lobby is functional rather than glamorous. Part of the complex operates as short-stay serviced apartments under The Capital brand, so owner-occupiers share the building with hotel guests, and pets are not allowed in the condo tower.
