Bayleaf is a timber-framed house with a central hall, heated by an open fire, dating mainly from the early 15th century. With replica furniture and equipment, the farmstead is presented at Singleton as it might have been in about 1540. Its floor area is not large but its height and proportions create a sense of grandeur.
The position of the hearth in the open hall is based on the evidence of hearths discovered by archaeologists in similar houses. Prior to the insertion of the brick chimney stack in 1636, the smoke from the fire may have originally been meant to escape through apertures formed in the ridge of the roof, but in practice most of the smoke seeps out through gaps between the roof tiles. The main pieces of furniture in the hall are the table, laid with a cloth, and a cupboard, on which pewter is displayed.
