The 15,000m 2centre will be the first scheme of its type, conceived to deliver a 'joined-up' judicial process.
In this 'flagship scheme', crown, magistrates and civil courts will be brought together in one building alongside other statutory agencies involved in the judicial process.
These include the probation service, the crown prosecution service, victim and witness services and youth offending teams, and Warwickshire Police operational services.
HLM's new building, which site within the Central Leamington Spa Conservation Area, will replace two 1970s buildings to create what the architect describes as a 'civic statement' that also respects a neighbouring listed building.
The practice was particularly pleased to win CABE's support. 'We are supportive of this scheme and feel that it has the makings of a good civic building, one which could complement and enhance its contexts,' the design watchdog said.
