Work will now start in October at the 27-acre Heston site following endorsement from the Mayor of London and the Secretary of State.
Specialist sports pitch constructor White Horse Contractors will design and construct the hybrid turf football pitches that will take 9 months to complete.
The project will include the hybrid playing surface GrassMaster, a comprehensive drainage system, full irrigation, energy efficient under-pitch heating along with wider site infrastructure.
David Smith, MD of White Horse Contractors, said: “The elite pitch development showcases the club’s vision and investment for the future, providing their players and staff with the very best facilities to play and train on.”
Work on the new training ground building, which has been designed by architects Studio Zoppini Architetti and engineering consultants Buro Happold, will start before the end of this year.
QPR CEO Lee Hoos said: “Investment in infrastructure, such as a bespoke training ground, is the greatest indication of an ownership which is here for the long term and genuinely believes in the growth of their football club.
“The owners will be personally covering a significant portion of the cost and we will also be issuing a Bond to assist with the financing.
“This approach has been successfully carried out by Burnley and Norwich City previously.”
