NHER 48901 (Building record) - Lawn Farm

Farmhouse is small flint cottage of around 1700 greatly altered and extended around 1800.
Barn, very large, reduced in 1841 which date appears in brick letters with very elaborate ventilation grilles on the blocking wall. Evidence of second barn in form of similarly large flint all at right angles, now inside later outbuildings. These barns could also be of around 1700, but much altered in 19th century when courtyard of most unusual buildings added; arcades of brick arches varying from round-headed to four centred, low and narrow as if for individual animal doors. One section on lower ground level than other.
Flint channel between buildings, with Paris Basin millstone set in bank, is stated to be leat for watermill and/or turbine.
Farm may have been estate farm for the original Holt Hall before this was rebuilt on new site. E Rose August 1990
