Mentally handicapped children, who live with their family, want to stay somewhere else without their parents. Or they might want to party without their parents. Then they can go to a ‘lodge’.
Of course there is always good supervision and there are mentors present to look after the children.

In the Netherlands there are a lot of these houses. If you are interested you may take a look at www.eigeninvloed.nl
Here you can find addresses of the ‘lodges’ (logeerhuizen) in the Netherlands.
'Eigen invloed' means own influence.
