As this building showed minimal evidence for internal posts it has been constructed so that the roof rafters are ground fast, in order to provide additional strength to the large structure. Scots Pine, widely available in the Neolithic landscape, has been utilized in the main framework. Ash and Hazel make up the mainstay of the roof timbers over which reed thatch has been laid. Noticeable features of the building are the gable ends, with one representing a typical wattle and daub feature, and the other being made with split oak planks. Bronze Age house In 2021 the construction of Butser Ancient Farm's first Bronze Age house began, based on excavations from Dunch Hill on Salisbury Plain. This project is working in collaboration with Operation Nightingale, an initiative to assist the recovery of wounded, injured and sick military personnel and veterans by getting them involved in archaeological investigations. The Operation Nightingale team excavated the structure in 2020 and were then involved in its experimental reconstruction at Butser. The house was completed in October 2021. Iron Age roundhouses Situated within the Iron Age enclosure are six Iron Age roundhouse constructions. The largest of these is the Little Woodbury roundhouse with a diameter of and a 2 ring posthole construction. Estimated material quantities to build this house include of oak for the frame and posts, of Ash and Elder for the rafters, of thatch, of hazel for the wattle walls and of daub. Two houses are based on excavations from Danebury Iron Age Hillfort near Andover. These include CS14, a stake built construction with willow woven between the hazel wall stakes. The second Danebury house is CS1, constructed with oak plank walls in line with the evidence of a slot trench discovered in the excavations. This house is furnished with Iron Age style furnishings. The Moel Y Gerddi Roundhouse is based on excavations from Harlech in North Wales and is constructed in a two ring style similar to the Little Woodbury Roundhouse. Unusually this house also features a back door. In 2009 the internal posts were shown to be rotten and a successful experiment was conducted in order to replace the posts in situ. Two houses are based on excavations from Glastonbury Lake Village and constructed to be as lightweight as possible reflecting the building constraints imposed by the marshy ground conditions of the landscape around Glastonbury. House M59 and M74 both feature
