Forest in the Sky

Forest in the Sky

EDGE Advanced

Developed by Flamingo Dai Lai Joint Stock Company, Forest in the Sky is a unique real estate project with advanced green technologies located in Hanoi.

Vietnam’s Coteccons served as the construction contractor for the eco-friendly complex. Forest in the Sky pioneers a new sustainability standard for Vietnam, emphasizing a visual appeal that is grounded in durability, comfort and energy and water-conserving features.

With its distinctive architecture, the four sides of Forest In The Sky are covered with over 75,000 trees, including shrubs, vines and colorful flowers. From a distance, the building resembles a tropical jungle full of vitality and brilliance. From within the building, residents can enjoy a panoramic view of Dai Lai Lagoon and Tam Dao Range.

Residents benefit from lower utility bills as all homes feature energy-efficient lighting, external window shading and high-efficiency hot water boilers, ensuring the building is as “green” on the inside as it is on the outside.

Forest in the Sky has received final EDGE certification from SGS Vietnam.
