The main part of the house is of 5 bays: each bay originally articulated by a full, jointed cruck; the 3 central crucks are complete and partially exposed, the outermost crucks encased within the outer stonework. Part of the original wattle and daub walling remains and there is an internal partition of reset timber. Most of the beams and joists are roughly hewn and chamfered and there is a large cambered, chamfered bressumer over the fireplace in the sitting room to the centre of the range.
