Access

Let’s explore the route from BTS Asoke Station to the building through a photo guide

From BTS Asoke Station, take Exit 3 onto the skywalk. Keep walking until you pass the entrance to Interchange 21 (or specifically, the stairs just before it), then take the stairs down to ground level.

Once you’re down to the street level, walk toward the Phrom Phong side, and you’ll arrive at the building in about 3 minutes.

Upon entering the office area, a reception desk is conveniently located directly in front. For any tenant inquiries or needs, the Building Management Office is easily accessible on the Ground (G) Floor near the main lobby.

Lobby

The lobby makes a striking first impression, featuring clean, marble-style tiling and a bright, expansive interior that conveys a sense of modern elegance.

Elevators

The building is served by 4 passenger elevators. This number is proportionate to the floor count, ensuring modest wait times and smooth vertical transport throughout the day.

Furthermore, efficiency is set to dramatically improve: an advanced destination control system (DCS) is scheduled for installation by the end of 2025, which will require access-card authentication for enhanced speed and security.

Office Units

The unit plans offer significant variety by floor, with available sizes ranging from 70 sq.m. to 600 sq.m.

Some units feature unique rounded layouts. While these may require creativity in space planning, they present an exciting opportunity for interior designers to craft a truly stylish and distinctive office environment.

The office units utilize glass doors and wall panels to maximize natural light, creating an open, expansive feel that enhances the sense of space. To ensure comfort, the windows are fitted with sun-blocking film, effectively reducing UV exposure and keeping the interior cool.

The existing carpet can be replaced with your choice of flooring. You are free to install partition walls and new rooms, empowering you to fully customize your fit-out to reflect your corporate identity and operational needs.
