Planned group of farmyard buildings at Cog Farm

Rubble buildings, some limewashed and with slate roofs, some corrugated replacements in the unconverted sections. The 2 yards are divided by a central N/S barn and the transverse buildings fronting the yards are divided into twinned hammels with cambered-arched openings with loft above to right range. The left hand yard has a long stable range at right angles closing the western side of the farm; this has been extended forward in later C19 and includes a 2-storey gabled central bay with dovecote. Another addition is the 3-storey red sandstone gabled 'tower' block to front attached to the gable end of the central barn; this may have been an engine house with the more substantial construction being due to the housing of machinery for animal feed processing. The right hand yard was formerly covered in by a modern shed and the hammel arches are partly blocked; loft openings with sandstone voussoirs above. Cartshed and granary close the eastern side of the farm with cambered-arched cart openings along E side; loft above and loft steps at rear. At rear is a further barn added in line to the main barn with access from front courtyard created through hammel range and cart entry on the gable end; later addition to W side, the 2 now forming parallel gabled wings. Only the 2 E ranges remain unconverted into dwellings.

The most significant interiors are those to the rear barn and the stable range both of which retain early cast-iron roofs: arched-braced trusses with diagonal struts and central vertical members that join the 2 triangular parts of each truss together. The rear barn was lofted; later barn has simple timber trusses; the 'tower' has A-frame trusses; roof with staggered purlins to the cross range.
