Clifton Park, which dates back to the 18th century, is owned by Rotherham Borough Council and has a range of facilities that need upgrading.
Those include a bandstand, cenotaph, fountain and memorial gardens, rock garden, sports areas and children’s play areas.
The Heritage Lottery Fund has awarded £4.5 million to the council to help pay for the proposals.
A new children’s activity area will be built including a water play area to replace the existing 70 year-old paddling pool and a skate park. Extra funding has come from the Department for Children, Schools and Families through the ‘Play Pathfinder’ programme.
The 12-month project, which is joint venture between UCS Civils and sister company Linpave Building, is due to get under way later this month.
Managing director of UCS Civils Mark Murphy said: “This project is an important strategic opportunity for UCS Civils owing to its size and location."
