Just a 5-minute walk from Asok Station, Vasu 1 Building offers affordable rental rates despite its prime location, making it a cost-effective office option.
Vasu 1 Building (formerly Glas Haus Building) sits on Sukhumvit Soi 25 in central Bangkok. With excellent transit access and a full range of nearby amenities, it is a highly attractive location for an office base.
The nearest stations are BTS Asok and MRT Sukhumvit—both within a 5-minute walk—allowing smooth travel using multiple lines. Nearby are the Terminal 21 shopping mall and high-end complexes EmQuartier and Emporium, making the area ideal for lunch, shopping, and client meetings.
Benjakitti Park is also within walking distance, offering green space in the city. Cafés, restaurants, banks, and clinics are scattered throughout the area to support daily business needs. Luxury hotels such as Hyatt and Hilton are close by, convenient for business travelers and entertaining guests.
Let’s look at how to get there from BTS Asok Station with photos.
From BTS Asok Station Exit 3, walk along the skywalk and go down the stairs just before Interchange 21.
Head toward the Phrom Phong side, and you’ll arrive in about 3 minutes.
There is a reception desk directly in front of the office entrance.
The building management office is located on the G floor near the lobby.
The lobby features clean, marble-style tiling and a bright interior.
There are four elevators. Relative to the number of floors, this is sufficient, so wait times are modest. (Scheduled to be upgraded to a “destination control system” by the end of 2025. Tenants will use access-card authentication.)
Unit plans vary by floor (unit sizes available from 70㎡ to 600㎡). Some units have rounded layouts, which may require creativity in space planning; with interior design, they can be used stylishly.
Glass doors and wall panels create an open feel and make the office appear more spacious.
Windows are fitted with sun-blocking film to reduce UV.
Currently, carpet is installed, but you can customize the fit-out with your preferred floor tiles or carpet. By adding internal partition walls and new rooms, you can create an office that reflects your corporate identity.
Here are the views from the windows. For those working here daily, the outlook becomes part of everyday life—an important checkpoint when choosing an office.
The hallways are quite spacious, providing ample width for moving furniture and office equipment.
These were renovated after the transition to Vasu 1, resulting in a clean and refreshed space.
One complimentary parking space is provided per 100㎡.
• Additional parking fee: 2,000 THB + VAT
• Total capacity: approx. 180+ cars
UOB Bank and GHB Bank occupy retail units in the building. There are no restaurants inside, but as it is adjacent to the Jasmine City Building, employees often use the restaurants there.
