Overview
The Address Siam-Ratchathewi is the crown jewel of AP's "Prestige" portfolio. Completed in 2023, this 50-storey skyscraper creates a new skyline silhouette for Ratchathewi. The design theme is "Crafted for Elites," featuring interiors heavily adorned with Hermes fabrics and imported limestone.
With 880 units, it is a high-density project but manages to feel exclusive through its massive 3-meter ceiling heights in the lobby and common areas. It sits just 150 meters from BTS Ratchathewi, bridging the gap between the old town and the Siam shopping district.
Developer
AP (Thailand) revived their legendary "The Address" brand for this project after a long hiatus. It represents their highest specification level, exceeding their "Rhythm" and "Life" brands in terms of material quality (real stone vs. synthetic) and facility grandeur.
