In terms of overall design, this group belongs with those from November 1822. Nonetheless, a major difference is the addition of skylights which are placed on the roofline in front and to the rear of the high attic roof, which in itself acts as a clerestory level to light the nave and gallery. The skylights channel light down to illuminate the nave and chancel. This feature does not appear on any plan or elevation after this date and was abandoned, hence its separate grouping.
