Germiston House

I am intrigued by this place.
My memory of Germiston is of tenements and multi-story flats, bounded by railway lines and industry.
Of course once upon a time this was not so. I doubt if there will be anyone alive who can say that cliched phrase: "I remember when it was all fields".
Though I imagine in the early 20th Century, it probably was largely still fields and open space. Well from the little knowledge I have of the place it was probaly piggeries and whatever green space surrounded Germiston House..
I have been bugged for years as to the precise spot Germiston House stood and its orientation. I have seen various maps and pictures and I understand it probably stood in the area between Forge Street and what used to be Coll Street.
One account states that Germiston House was demolished in 1913, however there is a photograph, which has accompanying data stating that the picture (I will post lated) was taken in the 1920s. Another account states that it was demolished in 1926 to make way for a housing development.
