Ashford Borough Council has granted full planning permission to developer McArthurGlen for a development intended to include 38 new shops and 725 extra car park spaces at Ashford Designer Outlet.
A report to the council’s planning committee highlighted objections to the scheme on the basis that it could be the "final nail in the coffin" for a "pound shop laden" town centre.
However, planning officers recommended approval.
Their report said that the outlet centre attracted more than 1 million visitors to Ashford every year and that many users of the extension would come from outside the town centre’s catchment area.
It added that a retail impact assessment suggested the scheme was likely to have an overall positive economic effect on Ashford town centre.
Planners added that visual effects arising from the development proposals – including building a car park on pasture - would be limited by a range of measures including high quality design and use of green walls.
The proposals also include plans for six new restaurants and cafes, together with an events space and a children’s play area.
The developer has committed to funding a shuttle bus between the outlet, the town centre and the train station at weekends and during the school holidays, as well as enhancing walking and cycle routes from the station.
