Drawings 1 and 2 show preliminary designs for Pell Wall. The drawings were made in early March 1822, less than two weeks after Soane records his first meeting with client Purney Sillitoe (SNB 169). The house has a bombé front on the north side, which encloses a large drawing room with views of Market Drayton. The entrance on the east front leads to a long corridor and a geometrical staircase. Columns, arches and stairs break up the corridor into a variety of bays, framing views and encouraging movement through the space.

The earlier plan, drawing 1, shows the house as 71 feet 3 inches by 52 feet 1 and a half inches; drawing 2 has a plan 70 feet by 52 feet 1 and a half inches. Drawing 1 is wider in its central bay, resulting in a wider drawing room and enlarged corridors around the stairwell. The design of the entrance hall also varies, with the earlier drawing showing narrow windows flanking the entrance. Drawing 1 has erasures on the main stair, probably for correcting the number of risers. A rough preliminary design for the domestic offices has been added in pencil to both drawings 1 and 2, showing stairs surrounding an 'office court'.

Room labels in drawing 2 have been included by Soane in pencil and by another office hand in pen. Soane's inscriptions amend some room labels so that the library and eating rooms exchange places. The room on the bottom left hand side of the drawing has been labelled 'Mr Sillitoe's Room'; in later drawings this room would become the breakfast room (see drawings 32-34). The upper left and right-hand corners of the sheet have landscapes in pen and wash.

The Soane Office Day Books record that George Ives (an assistant) worked on plans for a house on 4 March and that Soane's pupils, Papendiek and Mee, worked on the plans for the rest of the week. It is therefore suggested that drawings 1 and 2 were laid out by Ives and finished in pen and wash (including landscape) by the pupils.
