Green Park is a business park near junction 11 of the M4 motorway on the outskirts of the English town of Reading. The park opened in 1999, and is currently owned by Mapletree. It covers 195 acres (79 ha) and comprises 19 office buildings arranged around the Longwater, a central lake and wildlife habitat. The buildings provide 1,500,000 square feet (140,000 m2) of office space, and in excess of 6,500 people work on site. The development has been awarded a national Civic Trust Award for its landscape design, architecture and community involvement.
