Kitchen (left room) with massive rough beam, sawn joists. Original roof structure complete, consisting of three pairs of scarfed crucks with rough pegged collars and paired purlins. Thatch and scantling underthatch fully visible. Cross-passage door blocked: it entered the kitchen underneath the stair, the latter a single-flight replacement.
