The facility, located on an area of land off Angraflat Road, will replace the existing Kelso High School.
In addition to a new school, sports pitches and parking areas have also been included in the designs.

In a statement, planning officials said the proposed school building would provide "a statement of quality and presence" in the area, but some landscaping issues will have to be addressed.
An earlier bid for planning permission in principle was supported by Councillors in 2013. Scottish Borders Council had been advised to approve the project, and on Monday consent was granted, subject to certain conditions. These include details about landscaping, signage, drainage and sewerage issues, as well as protection for wildlife.
