Building Entrance
The Viettel off-site studio is situated on a gentle slope next to a peaceful lake surrounded by lush trees. The complex includes six units: a welcome reception, a restaurant, and four studios. It is located in the suburban area of Hanoi, approximately 30 kilometers away, about a 40-minute drive.

Building Location
Viettel is a global telecommunications group headquartered in Vietnam with over 27,000 employees as of 2015. The company has offices in major Vietnamese cities such as Hanoi, Ho Chi Minh City, Da Nang, and others. Despite being a leading IT company, Viettel values offline communication. The off-site studio is located in a corner of the Viettel Academy campus, which offers training for engineers. The facility includes conference rooms designed for leadership meetings and discussions. It also serves as a short-term remote workspace for leaders seeking a quiet environment away from the bustle of the city.

Meeting Room
Six V-shaped wall blocks are freely arranged on the site, connected by an open corridor. Each block is based on a triangular floor plan, closed on two sides and open towards the lake and surrounding trees. The walls create an open book form, symbolizing openness with nature. The open side faces the environment directly, offering visitors a relaxing and immersive natural experience.

Open Corridor
The studio faces north and offers visitors the richest green landscape. The V-shaped walls are designed tall to block strong, glaring sunlight from the east and west, while also creating an impressive facade. The rooftop garden serves as an outdoor studio. Small square openings in the walls provide natural light and ventilation to the rooftop space.
