Barn At Undertrees Farm

The barn at Undertrees Farm consists of two linked barns that were originally separate structures. The barn to the east dates from the late 17th century, while the barn to the west is from the mid 18th century. Both barns are timber-framed and clad in weatherboarding, with roofs now covered in corrugated iron.

Access to the western range is through a pair of barn doors located on the north elevation. The eastern range features three bays, with principal arcade posts resting on aisle plates that are now level with or below the existing floor level. It has a staggered butt side-purlin roof with a hip to the east. Carpenter's marks on the arcade braces, numbered from west to east, indicate that the structure is complete. However, the absence of evidence for a hipped roof on the west suggests that this barn may have originally been built against an earlier structure, which was later replaced by the current western range.

The western range has four bays, with aisle plates resting on low red brick walls and a staggered butt side-purlin roof, but it is shorter than the adjoining eastern range, spanning only three common rafters.
