Description
The barn at Green Meadow is a 19th-century structure built from rubble stone and topped with an asbestos sheet roof. It features two cambered-headed barn entries, which are framed with stone voussoirs. The end walls of the barn have two vent loops, one positioned above the other. At the rear, there are two similar doors.
Inside, the roof is supported by four oak tie-beam trusses that include a king post and angle struts.
