Hall Roof Beam Bay (Village Hall and Community Events)

One bay of a village hall roof: a 10 m stained tie beam, two rafters up to a ridge at 1.9 m, a king post, struts, five purlins carrying the next bay and steel straps at the feet. Bays repeat on the 2 m module and rest on y=0, so the scene lifts them to the wall head.
