Developer National Grid Property (NGP) said that the 45ha former gasworks site would include a small loch, paths, bridges, 1,000 trees and grassland.
It will form part of the Forth Quarter area, which also comprises the Telford College campus, a shopping complex, 6,500m2 of offices and 2,000 homes.
"We have committed a lot of thought and investment to the park," said NGP head of sales Stewart Macintyre. "It will create a valuable amenity and a highly attractive environment for people buying homes, students studying at Telford College and the wider local community. There will soon be a new and growing community here."
