A centre for children with severe learning difficulties in Grantham will be demolished and replaced with a single-storey building.
The work is due to take place in phases so that the existing centre can be kept open while work takes place until the new centre is built.
The residential home accommodates children with Multiple Profound Learning Difficulties (MPLD) and Severe Learning Difficulties (SLD).
A spokesman for Lincolnshire County Council, which runs the centre, said: “The current Beacon centre will stay active throughout construction, which means the proposal will be constructed in phases on the existing Beacon site.”
The new build will have a car park for 13 vehicles, seven more than at present.
Last year the Journal reported on how the county council was revising its £3 million plans for a new children’s centre to cater for 15 youngsters. In 2013 the site was being used by seven children and parts of it were cordoned off because they were in such a poor condition.
