Hei Tower is a Grade B mixed-use building located at1 Nguy Nhu Kon Tum Street, Thanh Xuan Ward, Thanh Xuan District, Hanoi. The developer is a joint venture between Hanoi Power Corporation and Hanoi Power Investment Joint Stock Company – two entities with a strong technical infrastructure foundation, which is directly reflected in the building’s power systems and overall operations. The project broke ground in 2011, was completed and handed over in 2013, and is built on a total land area of 5,105.90m² with a construction density of just 41.9% – creating an open, airy environment rarely found in central Thanh Xuan.
The building sits at the intersection of Nguy Nhu Kon Tum and Vu Trong Phung streets, a well-connected location providing easy access to southern Hanoi’s key arterial roads: Le Van Luong, Khuat Duy Tien, Nguyen Tuan, Ring Road 3, Thang Long Boulevard, and Nguyen Trai. The Thanh Xuan – Cau Giay corridor is home to a dense concentration of government agencies, multinational corporations, and bank branches – an environment highly conducive to business and partnership networking. The office block features an entirely separate lobby and entrance from the residential block, ensuring professionalism and privacy for tenant businesses.

Technical Specifications
With a developer rooted in the power sector, Hei Tower’s technical systems are built to a particularly rigorous standard. The backup generator operates 24/7 at 100% capacity – a benchmark few Grade B buildings in Thanh Xuan can fully meet. The elevator system comprises 4 units: 3 high-speed passenger lifts and 1 service elevator dedicated exclusively to the office block, with no sharing with residential floors above. Central air conditioning maintains a consistent temperature throughout the entire office block.
