The total build cost using Wates’ ADAPT building model is estimated at £16m with a 56-week build time.
The brand new 900-place school for students aged 11 to 16 years and 215-capacity sixth form facility would be built alongside the existing school.
Upon completion of the new building the old one will be demolished to make way for a landscaped green space.
Wates will also deliver a combined facility to bring together Monks Hills Sports Centre and a community facility.
The ADAPT model can produce a 21% reduction in build programme and cost savings on average of 23% against a typical BSF school building.
Work on the site is due to start this summer subject to planning permission, with completion scheduled for the new academic year in September 2014.
Ian Vickers, Managing Director for Wates Construction London and South, commented: “Throughout the design process we have kept an open book approach with both the Academy and Croydon Council and this partnership will deliver a flexible teaching facility that will continue to meet the future educational needs of the Academy.
“The project will become a true testament to how Wates and CPMG’s ADAPT schools solutions model can facilitate the cost and time efficient delivery of high-quality, inspirational learning environments.”
Nick Gregory, Director at CPMG Architects, added: “We are delighted to be supporting Wates in the design and delivery of another exceptional learning environment.
“The proposals have been developed to create a truly aspirational learning environment for the young people of Selsdon and to support the vision of the Academy and Coloma Trust.”
