One other plan is given (Fig. 231) as an example of Thorpe's ingenuity in planning. It consists of three rooms arranged within a circular balustrade and surrounded by a circular terrace. The angles formed where the three rooms join are occupied by three towers, one of which contains the porch, the other two the staircases. On the ground floor one of the rooms is the hall, one the parlour, one a bedchamber. The kitchen was to be under the hall. It should be observed how the large fireplaces are arranged so as to occupy some of the triangular space enclosed by the three rooms; and how the odd corners left are devoted to the buttery, a closet, and a wood store. The bay window is different in each room, and is so planned as just to extend outwards as far as the surrounding balustrade. Having thus examined the main features of the design, observe how a number of alternative sketches have been made for filling in with cupboards the angles made by the circular walls of the turrets and the walls of the rooms: observe also that on one of the circular staircases an equilateral triangle has been drawn, evidently as an alternative way of treating the turrets, and observe further how in the parlour and bedchamber a suggestion is made to have a semicircular recess at one end, such as was not infrequent late in the seventeenth century, but which never occurs in an Elizabethan plan. All these points are interesting, because they show how the draughtsman elaborated his design; and when he had finished this, he sketched a variation of the same idea at the side, in the upper part of the sheet. He was also undecided about the position of his steps on to the terrace, for he drew them first in three sets, opposite to the three bay windows; afterwards he sketched another set in pencil (shown by dotted lines on the drawing) in a more convenient situation just opposite the porch, and wrote on the old set "Stayres heare," and on the new "or heare." On his main staircases, too, after drawing the steps, he has crossed out three or four and written "half-pace," which means "half-landing." It will not be uninteresting to add to these illustrations of Thorpe's plans a list of the names of apartments, &c., to be found in his book appended to one or other of the drawings.
