The main house was originally built (ca 1790) for a merchant and subsequently had various owners before ‘cottage houses’ for orphaned children were built in its grounds (ca 1900).
These was modelled on the cottage houses in Fazakerley in Liverpool, the place with the nice hall and clocktower (which is still derelict).
The main house became a children’s hospital in the 1940s, then from 1991 on was used by the NHS as offices.
The main building closed its doors in 2015 that I can confirm!
The rest of the building is pretty mundane but does have a few interesting features.
But its mainly about that stairwell
Thanks for looking
