Description

The Waggon shed at Llawr Llan is a structure built from rubble-stone and features a low-pitched slate roof. The western wall serves as the boundary wall for the farmyard. The southern end of the shed is open, revealing an exposed roof truss.

The roof is supported by late 19th-century pine tie-beam trusses, which include a vertical metal rod and timber angled struts. The shed consists of four bays, although it was originally designed with five. There are two purlins supporting the roof.
