Located in Xuan La Ward, Hanoi (following administrative merger effective from July 1, 2025), Starlake Tay Ho Tay urban area is master planned across nearly 186 hectares, with a vision to become the new administrative and diplomatic center of Hanoi. It brings together key government offices, embassies, commercial - entertainment hubs like Lotte Mall Tay Ho, Hoa Binh Park, and a grand central square.
According to Savills Vietnam's 2025 Report, Starlake is considered the leading area for Grade A office supply among Hanoi’s satellite urban zones. The integrated infrastructure, seamless connectivity, and high-end projects positions Starlake as an ideal destination for corporate relocation, particularly among IT, finance, and consulting firms seeking green office spaces in Hanoi.

Transportation Infrastructure - A Key Connection Hub in the West
Starlake Tay Ho Tay boasts a modern, integrated transportation infrastructure:
- 40m-wide internal roads provide direct connections to the central square and various government ministries.
- Proximity to Vo Chi Cong Street and Nhat Tan Bridge, just 25 minutes to Noi Bai International Airport.
- Metro Line 2 (Nam Thang Long – Tran Hung Dao), set to break ground in 2025 and complete by 2029, will significantly improve connectivity and public transit access.
- Major arterial roads like Pham Van Dong and Ring Road 3 ensure quick connectivity to core districts like Cau Giay, Ba Dinh, and Dong Da.
This robust infrastructure not only enhances real estate value but also positions Starlake as a prime location for developing Grade A office buildings, hotels, convention centers, and corporate headquarters, attracting global investors and business communities.
