John Hiram Haycock (1759-1830) was an architect who built many notable buildings in Shropshire and Montgomeryshire. He was the son of William Haycock (1725-1802), a carpenter and joiner of Shrewsbury. J H Haycock was apprenticed to his father and became a freeman of the Shrewsbury Carpenters’ and Bricklayers’ Company in 1796. From about 1814 John Hiram Haycock worked in partnership with his son Edward Haycock, Sr. In 1824 he became the Shropshire County Surveyor.
