Tiptofts is a grade I listed building, on the site of a Scheduled Ancient Monument. The timber-framed aisled hall has a hammerbeam roof thought to date from the fourteenth century, whilst the cross-wing to the south was thought to be the remnant of an earlier phase. This report covers the dendrochronological analysis of timbers from both the aisled hall and the cross-wing. The results indicate both sections are probably late-thirteenth century in date, and may be contemporaneous.
