William Langham (1589-1651), the son of John Langham of Northampton, moved to London in 1619 and then to Burwash in Sussex circa 1625. He built Bateman's near Burwash of local sandstone and the tiles of the hipped roofs and six chimney stacks were made from Weald clay. The date over the entrance porch of 1634 places when it was built. Langham had created a substantial estate based on the mansion at Bateman's when he also purchased the manor of Burgherssh [Burwash] and tenements across East Sussex from Benjamin Wybarne, esq. in 1630 and indeed Bateman's may be built on the demesne land of that manor. In addition, Langham leased Dudwell Park, Halton Farm and the manors of Burwash and Poundsford from Sir John Pelham.

On the death of William Langham in 1651 his estate and Bateman's passed to his heir Alice Langham, daughter of his brother Edward Langham of Northampton. She married Joseph Newington (1606-1686) of Witherenden in Ticehurst on 1st October 1657 at Burwash and they sold the manor of Burwash to Edward Polhill, esq. and Anthony Knightsbridge, esq. in 1664. The Newingtons sold Bateman's to John Butler at some point prior to their death - Joseph in 1686 and Alice in 1687.
