Lake Cottages, Wavertree

I have a death certificate of great granma stating that her death in 1899 was at 4 Lake Cottages, Wavertree, Liverpool. I know this was not her place of residence so am wondering if it was a hospital. I have Googled the address but only come up with Lake Road.
Can anyone enlighten me please?

Thanks,
Vivwill

Hi Viv,just wondered if it was part of "Olive Mount" hospital,as some of the buildings there, were small self contained units,with various names,and there used to be a lake,almost opposite!Do you have any idea what her condition was?
