A timber-frame building, especially if it is constructed of oak, can often be accurately dated by dendrochronology (tree-ring dating). Several buildings in Hungerford have been studied by Dr Andy Moir, of Tree-Ring Services. One such building is 85-86 High Street, which includes timbers felled in the winter of 1448-49, and was therefore probably erected in 1449, 50 years after the death of John of Gaunt.
An estimation of the date of timber-frame buildings can be made by matching a range of features to a summary of typographic features (the one below relates to Surrey, and is based on one kindly provided by Andy Moir:
