That's why I thought it might be that one
They had probably got it via compulsory purchase but it had been empty a long time! My Mom always told the tale of looking out of the window to see a herd of cows in our drive, after this happened a few times she just opened the gate and let them out onto Tanworth Rd! She was used to cows as she had spent 8 years in Wiltshire around farms and cows!Would the council have owned the farm? Or did they compulsory purchase it before building?
Did you ever solve your puzzle? My daughter recently moved into a place just about where you are talking, it’s an old farmhouseLived in small Lodge on Tanworth Lane mid 60's, it had a well in the garden. My Dad worked for Solihull Council and said they owned it and the big house. He is dead now and would love to know the name of the big house, was it Tatterpool Farm?
