Award-Winning Project

Potomac Chapter ASLA awarded HOK with an honor award in the Design-Built Category for LG North American Headquarters in Englewood Cliffs, NJ. The campus was previously covered with asphalt and had little usable outdoor space. This project ultimately expanded green space on the premises by 50% and includes green walls and gardens, as well as amenities like outdoor dining and walking trails. EDA Contractors was proud to contribute to expanding the green space on this site, by working on 40,000 square feet of green roofing. This was in addition to the 190,000 square feet of hot fluid applied waterproofing and 150,000 square feet of concrete and wooden pavers.
