The Government Savings Bank (GSB) is revitalizing the Chaengwattana Government Complex, opening Building C as a model Smart City for the public sector.
Government Savings Bank opens Building C. The Government Complex in Chaengwattana showcases a smart office building built to government standards, integrating clean energy, technology, and a comprehensive lifestyle space under the "Road to Sustainnovation" plan. Aiming to support 25 agencies. By the year 2570.

Dr. Theethat Suksa-ard, Acting Managing Director of the Treasury Department's Asset Development Company Limited (TDAD). The Government Housing Bank (GHB) revealed that it currently operates in two business areas: managing the Government Complex on Chaeng Wattana Road and developing buildings on state-owned land for the government sector.
The strength of the Government Housing Bank (GHB) lies in developing energy-efficient and environmentally friendly buildings that meet Thai Green Building standards. Most recently, they developed Building C at the Government Complex, a smart office building meeting government standards, along with commercial spaces, service areas, and modern lifestyle shopping. The GHB is also moving forward with its “Road to Sustainnovation” strategy, establishing itself as a model smart city.

Building C is a flagship building marking the organization's 22nd anniversary and is a Grade A government office building that integrates technology, energy innovation, and Universal Design concepts under the "Road to Sustainnovation" strategy, driving the government center towards becoming a tangible Smart City model.
Dr. Teerach stated that the difference between Building C and typical government buildings is that it is designed as a model for energy-efficient and environmentally friendly buildings based on the BCG Model, incorporating "Universal Design" to accommodate all user groups.
The building is equipped with solar panels that generate over 2,200 kilowatt-hours of electricity per day, along with a Solar Shield envelope that reduces heat from sunlight by up to 37%. It also utilizes a passive cooling system combined with a radiant floor.
The central cooling system (District Cooling) distributes coolness evenly and reduces energy consumption. For air quality, a MERV-13 filtration system is installed to capture over 85% of PM2.5 dust and bacteria. Furthermore, over 60% of construction materials are sourced domestically to reduce carbon emissions from transportation.


“The heart of the building is the Intelligent Operation Center (IOC), a real-time data control center connected via the GCC Super Application, providing services such as Smart Parking, EV Bus tracking, maintenance requests, and in-building navigation. It also features the METTRIQ AI Prediction system, which analyzes energy usage trends and predicts equipment failures in advance, reducing long-term risks and costs.”
Currently, Building C and the Phodduang Building have a combined area of 510,000 square meters. Seventeen out of 25 government agencies have already moved in, including the Office of the Ombudsman, the Administrative Court, and the Office of the Permanent Secretary of the Ministry of Digital Economy and Society. It is expected that two more agencies will move in by 2026, and 100% occupancy will be achieved by 2027.


The Phodduang Building will comprise over 29,754 square meters of commercial space, developed into a modern shopping and lifestyle hub. This includes: Floors 1-3, a central hub for shops, restaurants, cafes, banks, and other services such as a fitness center, club, and a sub-healthcare center outside of Ramathibodi Hospital; Floors 4-5, offering over 5,000 square meters of co-working space and serviced offices, accommodating 2 to 50 people, catering to modern work needs; Floor 6, commercial space; and Floor 7, over 2,000 square meters of meeting, seminar, and banquet facilities, capable of hosting large-scale corporate events for over 1,000 people.
Government assets reached 4.4. Ten billion
Dr. Theethat stated that, in the past, the Government Housing Bank (GHB) has managed the Government Complex Buildings A, B, and C, as well as assets for the Treasury Department, such as the Phaholyothin Office Building and the Excise Department's multipurpose building, totaling over 44,348 million baht. This represents a significant increase from 23,163 million baht in 2564, reflecting GHB's full leadership role in public sector real estate development.
In addition, the Government Savings Bank (GSB) has signed an MOU with the Government Lottery Office to develop office buildings, printing facilities, and residential housing on state-owned land in Bangkok and Nonthaburi, aiming to develop two projects per year.
All projects adhere to Thai Green Building standards, designed according to the needs, budget, and financing structure of each organization. The transformation of over 138 rai of green space into gardens and creative activity areas provides recreational and exercise opportunities for personnel and the public, open daily.
“Therefore, the opening of Building C is not just about adding office space, but it's the beginning of upgrading the Chaengwattana Government Complex to a Smart City model for the public sector, tangibly integrating technology, sustainability, and lifestyle. This is in line with our goal of accommodating 25 government agencies by 2570, in full accordance with our Road to Sustainnovation plan.”
