This photo was taken in the Summer Term of 1977 and shows the remains of huts 31 and 29, with workmen beginning to demolish 27.  The photographer is standing on the site of Butler Hall (33) which was the first of the row to go.  At the end of their lives, 31 was the Geography block,29 was English and 27 was Maths.  Butler was dismantled carefully to preserve corrugated iron sheets needed elsewhere for repairs.
