Last October Derbyshire County council approved funding to bring the 750-pupil school on to one site at Doe Hill Lane.
Since then designs have been drawn up by Maber - which has offices in Derby and Nottingham - and planning permission approved for the building.
Local contractor Tomlinson started work on site in June and the project is due for completion next autumn.
The new school will include a sports hall, library, specialist and general teaching areas and offices.

It will also include a facility to allow students with autism to learn alongside their peers.
New playing fields, hard-surfaced games courts, athletics facilities and a full-size artificial football pitch will be provided.
Councillor Mike Longden, our Cabinet Member for Education, helped to lay the foundation stone for the new building. He said: "We have recognised the compelling need to provide this learning community with a new school.
"The county council has pulled out all the stops to make the new school a reality and this is the start of the last full academic school year for pupils at its present site.
"I'm delighted that we have been able to put together a financial package to deliver our promise of a new school for Tibshelf.
"It means we can provide the whole community with a bright and spacious school which meets modern standards and will enable pupils to reach their full potential."
