CornerStone Building

CornerStone Building is one of Hanoi’s most prestigious Grade A office developments, strategically located at 16 Phan Chu Trinh Street, Cua Nam Ward, Hanoi (formerly Hoan Kiem District), in the heart of the capital’s traditional Central Business District (CBD). The building seamlessly blends French semi-classical architecture with contemporary office design, creating a distinctive corporate address in one of Hanoi’s most sought-after business locations.

Completed in 2013, CornerStone Building comprises 14 above-ground floors and 3 basement levels, offering approximately 25,893 m² of net leasable office space and one of the largest floor plates within Hanoi’s CBD. With floor areas of up to 2,000 m² per floor, the building is particularly attractive to multinational corporations, financial institutions, embassies, professional service firms, and large domestic enterprises requiring efficient and contiguous office space.

Designed to international Grade A standards, the tower features high-performance curtain wall glazing, centralized air-conditioning systems, raised technical infrastructure, premium finishes, and advanced building management systems. Occupiers benefit from 7 Mitsubishi passenger elevators and 1 service elevator, backup power systems with up to 30 hours of operation, dedicated pantry areas on each floor, VIP facilities, and high-quality indoor environmental controls. The building also provides one of the largest parking facilities in the CBD, accommodating approximately 200 cars and 2,000 motorcycles across three basement levels.

A key differentiator of CornerStone Building is its commitment to sustainability and operational excellence. The property achieved LEED Platinum Certification for Operations & Maintenance (O+M) in 2025, becoming one of Hanoi’s leading green office buildings. Sustainability initiatives include rooftop solar panels, energy-efficient building systems, advanced air filtration technologies, and the use of 100% emission-free electricity as part of its long-term decarbonization strategy.

The building enjoys a prime location within Hanoi’s financial and governmental district, adjacent to the Ministry of Finance and close to the State Bank of Vietnam. It is situated approximately 400 meters from the Hanoi Opera House and 800 meters from Hoan Kiem Lake, with numerous five-star hotels, embassies, government agencies, and luxury retail destinations within walking distance. This unparalleled accessibility and prestigious address continue to make CornerStone Building one of the most desirable office destinations in Hanoi.
