In 1951 Earl Spencer of Althorp offered the estate for sale by auction which included the house, Bury Farm and five enclosures of arable land. It then became Aylesford House School which had moved from London Road in St Albans. Later Aylesford House was absorbed by Hardenwick School.

In 1978 Richard William Thrale, co-author of Historic Sandridge, bought the whole of the very dilapidated main building at Sandridgebury and saved it from demolition.

A considerable amount of remedial works was done to convert the mansion into three superb establishments. A complete re-roofing were commenced even before completion of the purchase. A dividing wall was built from the cellars to the crutch of the roof, and one unit was sold in November 1979.

Richard Thrale continued to refurbished the shell into a beautiful home that became known as Sandridgebury House and took up residence in March 1981. The Old School House and coach-house were separately divided off, occupied and refurbished. Sandridgebury is now home to four families and the Thrale family are resident is Sandridge once again.

I have, by chance, come across your website and it is of particular interest, as I was at School in Sandridgebury in 1956/7.

I note that Hardenwick has or had taken over the Aylesford School and I would like to contact this school to enquire about an alumni. Could you help?

Yours most sincerely,

Graham Forbes.

Just to add that after Hardenwick boys' prep school, around 1969 the school was bought by the MacIver family from Boston to run a private boarding school for US high school children. This school closed around 1973.
