Housing, offices and a new retail outlet could be built on the Northamptonshire Police headquarters site, the county council has revealed.
It was announced by former Police and Crime Commissioner Adam Simmonds earlier this month that part of the land had been sold for £3.3 million to the Education Funding Agency to build a new school.
Northamptonshire County Council also owns a large proportion of the site and the local authority has now begun planning how the rest of the land could be used.
A Northamptonshire County Council spokesman said: “Now that plans for a new free school at Wootton Hall have been confirmed, we are working with Northamptonshire Police and the Northamptonshire Police and Crime Commissioner to examine the potential of the site.
“We have commissioned consultants to explore the potential for mixed development on the site, which could include housing, employment, retail and leisure, while retaining an element of open space/sports pitches.”
The new Wootton Park School is set to open in temporary buildings this September.
The majority of Northamptonshire Police staff are expected to be off the site by September 2017. Two new buildings, situated just off the A43 next to the A6003 between Kettering and Corby, are being constructed to house about 350 staff.
A new £1 million roundabout is currently being built to improve access to the Wootton Hall site from Mereway.
