Although present house is largely C18 in character, an older building may have existed on the site. The exposed timbers in exterior wall of Pentwyn may be part of an earlier timber-framed house, later encased in stone. Whatever its origins, the house was substantially remodelled in the early C18 to form the present Renaissance-style farmhouse. In C19 new windows were inserted, since then there have been few changes. The 1843 Tithe Map marks the house as belonging to Elizabeth Taddy (Llantilio Court) and occupied by David Jones.

The attached corn barn is probably early C18, the granary probably early C19, and the dairy and cowhouse later C19.
