In the mid 18th century the street (south) wall was refaced in brick, and sash windows (Georgian windows) were added with a projecting brick cornice above. The roof was raised to line up with the roof of the adjacent building to the west (No 31), and was tiled. The line of the eaves (bottom edge) of the original roof level is still apparent in the exterior street frontage (south) wall from the five circular (painted) metal ends to the tie-rods which hold the building together widthways, which are visible in a line between the middle of each of the sash windows on the first floor. The pitch of the original roof appears to have been approximately 51 degrees above the horizontal, while that of the 18th century trusses is 45 degrees, so the later (present) roof has a less steep slope than the mediaeval one.
It is probable that the position of the earlier door into the former hall was moved to the centre of the rebuilt south wall at this time, and that sash windows were inserted either side at ground floor level, but no evidence of this change survives.
