The interior has been modernised and replanned. A central hallway leads back to the re-set features of the late C17 rebuilding. The mid C17 dog-leg staircase has moulded strings and handrail, flat strip-balusters and square newels with shaped finials and drops; the bottom newel has a carved lion in a seated position at its base. Beneath the stairs is a reset doorway, square-headed with moulded jambs and carved strips with fleurs-de-lys; the plain door with its wrought-iron hinges is original. At the head of the stair, is a similarly detailed doorway with a central shield flanked by lions, carved in relief on the lintel; the shield contains the initials and date: B / W F / 1655. In the bedroom at the head of the stairs is a reconstructed fireplace containing acanthus, egg-and-tongue, bead-and-rail and carved scrolls and consoles, all painted and with a modern central mirror above the mantel. A panel above the opening has a motto and the initials and date: B / W F / 1662 and above the mirror is a cartouche with arms of Hwfa (for William Wynn alias Bold). Flanking the mirror are painted shields of arms.
