Runnymede Pleasure Grounds, on the banks of the River Thames between Egham and Windsor, is a popular destination but the facilities there are in need of refurbishment.
The Council, as trustee of the site, is preparing to replace the café, paddling pool, play area and upgrade the parking.
The final plan, which has come about after consultation with local people and organisations, includes a new café situated further back into the park, giving views across the grounds and to the Thames.
This building could also serve as a restaurant and will include a multi-use room for use by up to 70 people. This space will be available for business meetings, educational events, seminars and performances such as comedy nights and theatre.
The Council also envisages a modern play space with equipment for children of all ages. A modern splash park will replace the existing paddling pool, and the pavilion building will become an improved food outlet with outdoor seating.
The designs ensure that most of the activities will remain on the east side of the site, leaving the west side as an open grass area with tranquil spots next to the river.
The Council also plans to provide holiday accommodation on the edge of the site, in the form of two new lodges and a converted cottage, to provide an income to help fund the scheme and maintenance of the pleasure grounds in the long term.
The plans were discussed by councillors on Thursday 14 March and the planning application will be submitted within the next few months. It is estimated the project will be completed by late 2020.
The Pleasure Grounds benefit from a fantastic riverside location with wide views of the river itself and the beautiful Coopers Hill slopes. It is also a short walk from the Magna Carta and John F Kennedy memorials, within the National Trust Runnymede site nearby.
