We are expanding our operations to six countries across ASEAN, which will also support growth in this region. Today, we are delighted to introduce Siam Pathumwan House to everyone and hope it serves as a model for the future of office spaces that promote innovation, sustainability, and a balanced work environment for all.”

This 33-story office building stands 136 meters tall and offers a total of 51,000 square meters of office and retail space, located on Phaya Thai Road in the Siam Square area, a central hub with ample transportation options, including a direct sky bridge from the building to ONESIAM, the Pathumwan intersection, BTS Skytrain, Airport Rail Link, piers, and multiple expressways. Additionally, it is close to major commercial and cultural landmarks such as Siam Paragon, MBK Center, and Bangkok Art and Culture Centre. This prime location and excellent connectivity allow building users easy access to various amenities and services, enhancing the balance between work and life, as well as overall convenience.

Siam Pathumwan House is inspired by the Japanese concept of 'Koshi', perfectly blending functionality with aesthetics. It features large floor-to-ceiling windows that allow natural light to flood the space and provide city views. The design harmonizes natural elements with the urban landscape, creating a tranquil workspace amidst the hustle and bustle of the capital. The building also integrates cutting-edge technology and innovations from Hitachi and Daikin, which are part of Siam City Group, including the Hitachi Smart Building Platform for security, intelligent access management, and comprehensive surveillance. Simultaneously, it efficiently controls the building's temperature with Daikin's VRV (Variable Refrigerant Volume) technology, an intelligent centralized air conditioning system that enhances energy efficiency. Furthermore, it includes sustainable features such as light and motion sensors, heat-reflective glass, electric vehicle charging stations, water-saving systems, wastewater treatment systems, and more, which are crucial for achieving LEED Gold and Fitwel 1-star certifications.


In addition to these certifications, Siam Pathumwan House has also received WiredScore Platinum certification, the highest international standard for digital connectivity, making it the second building in Thailand to achieve this standard. This reflects its readiness to support digital technology connectivity, including comprehensive Wi-Fi coverage throughout the office space and secure data management. Moreover, the building has also received SmartScore Gold certification, emphasizing the effective integration of advanced smart technologies.

Siam Pathumwan House transcends traditional office building concepts, becoming a vibrant hub that combines artful design and lifestyle. It features numerous retail shops on the lobby level (L), M level, a food court on the 6th floor, and Club Siam on the 11th floor (Amenities Floor), managed by Glowfish, Siam City Group's partner and provider of high-end serviced offices under Heritage Estates. In addition to the serene atmosphere in this space, there is also Club Siam Eatery & Bar and a multifunctional lifestyle area designed for relaxation and social interaction. The building also showcases artworks from several renowned artists, such as the Kusama Pumpkin, the first large orange polka-dotted pumpkin in Thailand by world-famous Japanese artist Yayoi Kusama, and contemporary wall art styled as Breast Stupas Valentino by Thai artist Pinree Santapithak, who conveys stories and culture to inspire.
