The barn at Wimbish Hall in Essex is probably seventeenth century although it may be earlier. It is a timber-framed, aisled barn with clapboard cladding and a clay-tile roof. There are two wagon porches on the east side.
The barn has been in continuous agricultural use for at least 300 years and probably more. It has undergone a number of alterations, most noticeably the louvres on one porch and one end of the main barn. Many of the collar beams between the common rafters and some of the diagonal arched braces have broken or been removed, which has caused some racking (or raking) of the main trusses. In spite of this, the interior of the barn still fairly complete and still in agricultural use.
