Parkgate Road Tollbooth?

I was told, I can't remember where or when, that the building shown below was originally the tollbooth for Parkgate Road. It is in the back garden of a house in Enderby Road, which runs parallel to Parkgate Road, but my researches since have turned up nothing to either prove or disprove the assertion. Anyone else know anything more?
