Warwickshire Police have chosen the site for a £30m criminal justice centre (CJC) in the south of the county.
A CJC combines police, courts, crown prosecutors, victim support and probation services on one site.
Plans for one in the south of the county, due to open in 2008, had been delayed while a site was picked.
Princess Anne opened the first CJC at Nuneaton. The second will now be built on the site of the Mid-Warwickshire courts in Leamington.
Cases will be heard at Stratford Magistrates' Courts while the CJC is being built.
The plans will be on display at the Royal Priors shopping centre on Friday 24 February.
Chief Constable John Burbeck, on behalf of the agencies involved, said: "The centre will enhance the delivery of justice in South Warwickshire and enable closer co-operation between agencies resulting in more sharing of information to prevent and reduce crime.
"The success of the northern justice centre in Nuneaton has delivered increased public confidence and more inter-agency co-operation and we are confident that the southern justice centre will provide similar benefits."
