CornerStone Building is a Grade A office building located at 16 Phan Chu Trinh, Cua Nam Ward, Hoan Kiem District, Hanoi. Developed by VIB Ngo Gia Tu Company with a total investment of over VND 1,000 billion, completed in 2012. The building was designed by two international firms – Archipel (France) handling the overall concept and DWP (Australia) responsible for the façade and landscaping – and was originally constructed to serve as the headquarters of Vietnam International Bank (VIB). The current property manager is VIBank – NGT Limited Company.
The building’s architecture blends a semi-classical style with French romantic influences and contemporary elements – a deliberate design choice given its dual role as both a bank headquarters and a Grade A office tower. The façade is finished in premium materials with large-format imported glass on all four sides, maximizing natural light. The building is surrounded by green landscaping and decorative gardens, setting it apart from most other Grade A buildings along the Hoan Kiem corridor.
In October 2025, CornerStone Building achieved LEED Platinum certification for Operations & Maintenance – accompanied by the first-ever solar power system deployed for a Grade A office building in Hanoi, as part of a transition roadmap toward 100% zero-emission electricity.
Located directly adjacent to the Ministry of Finance headquarters, 400 m from the Hanoi Opera House, 800 m from Hoan Kiem Lake, and within 1 km of Sofitel Legend Metropole, CornerStone Building connects conveniently to major arterials including Hai Ba Trung, Ly Thuong Kiet, Ngo Quyen, and Tran Hung Dao.
