Highlights of Interchange 21

Surrounding Environment

Interchange 21 is strategically situated at one corner of the bustling Asok Intersection in Bangkok. Its ground floor and surrounding area are highly convenient, featuring an excellent mix of hotels, restaurants, and various shops. This ensures that the daily needs of office tenants and visitors are exceptionally well covered.

Key Consideration: Traffic Congestion
While the location offers outstanding connectivity, it is important to note the frequent heavy traffic congestion on  Asok-Sukhumvit Road intersection. Companies whose operations require frequent commuting or travel by car should factor this into their logistical planning.

Excellent Accessibility

Interchange 21 offers outstanding access, located only minutes away from both MRT Sukhumvit and BTS Asoke Station. This dual connectivity ensures fast travel across Bangkok. A key benefit is the direct, rain-proof entry into the building from both the BTS and MRT, meaning commuters and visitors stay completely dry, even during heavy rain.

Elevators

The Elevators are divided to a low zone and high zone. A sufficient number of elevators are provided, which successfully minimizes congestion even with many tenant companies in the building.

The View from the Windows 

The view from unit varies greatly depending on its orientation, making it an essential point to check during your inspection.

Recommended units face the Asok intersection, offering a truly “Bangkok-like” panoramic scene: the dynamic heavy traffic, surrounding skyscrapers, and the greenery of Benjakitti Park to the south.

However, caution is advised for units facing adjacent buildings, as they may have limited views. Similarly, units facing Soi Cowboy may be subject to evening noise, which should be taken into consideration.

Hallways

In contrast to the luxurious entrance, the hallways and elevator lobbies on each floor are simple and utilize a white color palette. While they are highly functional, they show minor signs of wear, consistent with an established and well-utilized building.

Pantry Area

The shared pantry area currently provides only minimal facilities, comparable to a very basic kitchen with a sink. The building announced plans for a renovation of this area, during 2022.Pantry areaThat concludes our introduction of the Interchange 21.
