Interchange 21 – Elevating Urban Mobility with NPD’s Smart Parking Management

Located in the heart of Sukhumvit and seamlessly connected to both the BTS and MRT, Interchange 21 stands as one of Bangkok’s most iconic developments. Since 2014, NPD has proudly managed its parking facilities under a long-term concession, delivering exceptional service and innovation.

For over a decade, NPD has operated under our signature “Happy Triangle” philosophy, elevating parking experiences through our 3S strategy:

• Service Up – Enhancing convenience and customer satisfaction
• Security Up – Ensuring a safe, reliable environment

To keep pace with modern needs, NPD has introduced a Smart Parking system with automatic license plate recognition and cashless payment options, streamlining every step of the parking experience. We have also installed EV charging stations, supporting the growing community of electric vehicle users.
