E plan
That especial plan, as for a large country house, whose general outline resembles the capital letter E. It is attained by arranging two larger pavilions at the two ends of the main building and a smaller one halfway between them; although in English country houses the end pavilions have rather the aspect of breaks in the main building which seems to be returned at right angles at either end, the lines of cornice, roof, etc., being continuous or nearly so. It has been though that this plan was sometimes used in compliment to Queen Elizabeth. (Sturgis, 1900)
