Residential care for a family - is this something that exists?

I find myself searching for support often as my situation has been desperate for a long time and I have always found the propect of residential support appealing, even if only temporarily so that I can, well, sort myself out, but it always seems to be just for individuals. I have a wife and three children, and all of us have ASD, ADHD or both, and we're not coping (massive understatement), but I think we could, we just need a high level of support for a short amount of time and then could taper it off. 

Does residential care for families, as opposed to individuals, exist?

Thanks,
James
