The council announced the move after it was awarded two more Green Flag awards last month for Radnor Gardens and Kneller Gardens in Twickenham, adding to the seven it retained from 2009.
Almost 300 residents took part in the Crane Park consultation earlier this year which will help set the tone for the improvements, work on which will start later this month.
Cllr Virginia Morris, Richmond Council’s Strategic Cabinet Member for Environment and Planning said: "I’ve been very impressed by the number and quality of suggestions people made. This clearly shows that local residents take a great deal of pride in Crane Park.
"We have promised to work closely with residents to improve our local areas. The Crane Park project has been a fantastic example of what can be achieved when the Council and local people really work together."
Following feedback the work will now include natural features and materials to enhance the character of the Park.
Entrances will be cleared, sight lines opened up and natural pathways highlighted.
Among the additions will be wildlife features including an insect hotel to act as a winter habitat for many species.
The work will be funded by the Mayor of London’s Help a London Park programme, announced in Crane Park last year.
Mayor Boris Johnson said last week: "It is great news that the spade is going into the ground, to kick off the works that Crane Park really needs.’
Crane Park won the Mayor’s Help a London Park competition last year and was awarded £400,000 to pay for improvements on both sides of the river. The competition formed part of the Mayor's London's Great Outdoors programme, a £220 million investment in London's public spaces over three years.
Cllr Morris added: "Thanks to the Mayor of London we have the money to make many of the ideas a reality. Now we know what people want, we can work with them to improve the park and make it a place which people will be able to continue enjoy well in the future.
"Crane Park is a high profile project for both boroughs (Richmond and Hounslow), and I hope when the work is finished, it will be seen as a great example of the good that can come about by working together. "
Among the improvements, entrances will be made more welcoming and accessible, river views will open up, selected overgrown areas will be cleared for conservation features, and furniture such as benches, picnic tables and signage will be installed.
There will also be new tree, hedge, wildflower and bulb planting and Government funding will pay for a new children’s play area made from natural materials.
