Of drawings 236 and 237 the former is obviously a preliminary sketch for the latter. They show the gated entrance to Pitzhanger with its two side gates and a partial view of the lodge on the right. All the hallmarks of Soane's earlier designs for the structure are there, and Richardson has shown only a glimpse of the house, in keeping with Soane's ideas on angles of perspective and the Picturesque.

One difference from earlier designs for the gated entrance can be seen in the addition of vase finials in place of pine-cones surmounting the canopy dome caps. At this stage, Soane indulged in a certain amount of theoretical re-design in the light of changed circumstances; the finial alteration could well be a feature of this.

These sketchbook volumes contain watercolours all by Soane's pupil C. J. Richardson, many of them being signed or initialled and in the same hand.
