Ideal location

Enjoy convenient transportation with the project’s ideal location on Rama III Road
in close proximity to Chaloem Maha Nakhon and Si Rat Expressways.


Cooler and airier working space

The building’s unique oval shape has no corners that can act as heat trap. In addition to protection from outside heat with insulated double glazing, the interior with 2.7 m-high ceilings also allows better ventilation for you to enjoy cooler, airier, and more comfortable working space.


Better energy saving
