A post mill was marked on a map of land owned by the Dean and Chapter of Norwich and Normans surveyed by William Cooke in 1718. The land the mill stood on was marked as owned by Normans. This may be the site of the Pockthorpe postmill or it may be a predecessor to the smockmill. As the land belonged to the Dean & Chapter of Norwich, the mills were always leased.

Pockthorpe smock mill with a ground floor diameter of 58 feet was built in 1769 on the brickwork of the roundhouse of a former postmill on the same site and was itself replaced by a towermill c.1815, built on the same site.
It would appear from the July 1769 advert, that despite being fitted with French burr stones, normally used to produce flour, the mill had been built to produce animal feed, although it was quite soon converted to flour production.
In 1803 the mill was using patent sails with a fantail to power two pairs of French burr stones, one pair being 5 ft. 3 ins. and the other pair 4 ft. 8 ins. By 1815 the mill was using 3 pairs of French burr stones.
In its later years, the mill was sometimes known as Jeckell's Mill.
