The three blocks, renamed Emmeline, Christabelle and Sylvia, are part of a set of seven towers close to one of Manchester's main arterial routes.
The 1960s structures are being given a new look, with the creation of grassed amenity space, planting and a hard-landscaped square of blue brick reflecting the industrial past of the neighbourhood.
Gross Max landscape architect Nigel Sampey, who designed the makeover, said the new look would update the towers, which are owned by Urban Splash.
He added: "It's quite a dramatic setting on the side of a river with the feel of a valley to it.
"We've used birch to plant the site itself and included private gardens. It has been quite a long process but the scheme is seen by planners as being a flagship for the area."
