We are informed this building, located in the sand dunes at the top of what is now the junction of Pizy Avenue and Trinity Rise, was one of the first experimental buildings made entirely of concrete. It was demolished after falling into disrepair.( JS Note see later images which may disprove this)
I have attached photos taken by my parents, Mr and Mrs Ellison, when they lived at “The Mount” Burnham on Sea 1949-1952. They loved living near the sea and in 1986 after thirty four years in Sutton Coldfield in the West Midlands they returned to Burnham on Sea. It was certainly a very grand house divided into flats at the time my parents lived there. I was only five when we went to the Midlands but I do remember playing in the sand dunes and on the beach next to the house.
Best wishes, Mrs Cynthia Boskett
