The original drawings for design B have not survived. These record drawings were, from the evidence of the watermark of the plan, made in 1811 or afterwards. Pencil notes on the verso suggest that they illustrated his lectures for a more general audience at the Royal Institution, c.1820. Soane's notes for those lectures - Extracts from different authors, drawings wanted and buildings compared (Soane case 159) has an entry for 22 June 1820 with a very rough plan (pen) labelled : A design to introduce Grecian arch. into the Chinese / dominions & to show how arch. may be abused / 22 June 1820 / Make a large drawing of a design / for an Imperial / dog kennel / Stud of horses / Master of the / Buck hounds / Master of the / Horse This design is inscribed to the / King of the Dandies - / In Russia the peasants / on an estate are considered / as making a part of / the purchase / Approach see Bagaria (Bagheria, Villa Palagonia, Sicily).

Given the lapse of time between 1778 and 1811-20 , it possible that Soane re-designed his scheme for a a doghouse in a Classical style and that these drawings are copies of a later, partly revised design. The lithograph plate (xxxiv***) in Designs for Public and Private Buildings (1828) shows an elevation for design B as well as a plan and elevation for design A. Comparing the latter with drawing 1 it can be seen that the plain ashlar facade now has banded rustication, the dome is ribbed and the cupola omitted, and the round arched doorways are emphasised by an incised line finished in a Greek key motif - a decoration used later in Soane's career. Of the archaeological sources, the frieze from the Temple of Vesta at Tivoli could have been known from visits, the dates of which are not recorded in Soane's Italian sketchbook. In any case, Soane would have known the building and its details from George Dance's drawings. Paestum was seen by Soane on 26-27 January and 14-16 February 1779 (see Italian sketchbook with notes, 1779, volume 39), though his visits may have come after the presentation of his two designs to the Bishop of Derry 'soon after' 29 December 1778. However, he could have known of Paestum from engravings or possibly the first published book on the subject, The Ruins of Pœstum (1767).
