I've just found it. Yes it did used to be a boarding school and was a much larger building before part burnt down in the 1980s. There were allegations of historic child abuse.
The property was built in 1834 (so it only just counts as Georgian - Queen Victoria came to the throne in 1837) and was a boarding school for 50 children between the ages of 8 and 14 originally run by the Quakers. It was even noted that each child should have their own bed!
There is an interesting history of the school available online.
"The school was to be conducted with rigid economy, and its essential character was to be that of combining with religious and moral instruction, the education of children in useful knowledge, with the addition of extensive manual employment, chiefly in agriculture, with a view to diminishing the expenses of maintenance and education."
In the 1891 census, it shows there was the head master, four male and four female teachers between the ages of 14(!!) and 30. Nine female domestic staff (housekeeper, cook, laundress, kitchen maid etc)
There were 46 boys and 21 girls there as boarders.
The school shut down in 1934 and then in 1939 a boys Approved School was set up there by Liverpool Council. In 1973 it became a "Community Home with Education"
The school closed in the 1980s and then suffered a major fire that led to a large part of it being demolished with the bit now being for sale the only part left.
Part of the land was sold off for housing and there is now also a daycare centre on what used to be the playground.
From the 1990s onwards several former employees at the home were convicted of historic sexual abuse.
Given it's history, that is not somewhere I would really want to live.
