Kier is the architect of plans for the 28-bed secure facility, which will be located in Bonemill Lane on the outskirts of the town and were approved three weeks ago.
The scheme, which is being funded by the Department for Education, will provide care for some of Lincolnshire’s most vulnerable children as well as being a national resource for secure accommodation.
Nick Heath, director at Willmott Dixon, said that the new accommodation will aim to achieve as close to a net zero in operation solution as possible with a design that is majority off-grid supported by solar panels and power storage.
The development will also feature a new service road, a car park, a surface water attenuation pond, and landscaped areas.
