Soane made at least four alternative designs (drawings 1-8) before he reached a conclusion (drawings 10-14).  The finished design has an inevitability about it that comes when plan and elevations are completely resolved.  

The kitchen and stables wings were not built.  Shown in the earlier alternative designs (drawings 1-8, 11) they were probably too expensive nor were the last designs (drawings 20-21) made a year later in April 1785, executed.  Something like the kitchen added by Soane to drawing 12 was built, enlarged in the nineteenth century and replaced in 1975 by a new addition.  Of the chimney-pieces designed by Soane, that for the eating room has survived. 

Two alternative plans and elevations were published in Soane's Plans, elevations and sections of buildings erected in the counties of Norfolk and Suffolk, 1788 (1789), plates 41-42. Plate 41 is close to drawing 11, the plan reversed as instructed on the drawing, so that, for example, the stair is on the right-hand side, the stables on the left instead of right. Plate 42 is close to drawings 4 and 5 (Design No.3) except that, for example, the office wings are omitted.  

There are references to Saxlingham Rectory in Soane's office Bill Book 1, Journals 1 and 3, Account Book 1781, Ledger A, Day Book 1792, Letter Book 1797-1801, Private Correspondence I.G.14 as well as in his Note Books.  MS indexes to the Note Books, Bill Books and Journals are currently only available for study at the Soane Museum.  There are plans to put these online. 

2 No 2 (Baldwin) and (added later by George Bailey, office assistant 1806-37, curator 1837-60)  Plan of the Principal Floor Design No 2 for The Rev^d John Gooch.  The four-part, square plan (37½ by 38 feet) has the kitchen offices attached to one side and stables on the other - both with semicircular courts; (verso) (pencil) incomplete section showing the profiles of Block[ing course], Corn[ice], Top of Cap[ital] and string course

3 N^o 2 (Baldwin) and (Bailey) Entrance Front of proposed House for The Rev^d J. Gooch  showing a five-bay house, 38 feet wide, with a pedimented three-bay frontispiece, pedimented porch with a pair of fluted Doric columns, the office wings each with a single window within a blind arch.

4 N^o 3 (Baldwin) and (Bailey) Plan of the Principal Floor design No 3 showing a four-part, rectangular plan with a semicircular porch and the offices as blocks on either side and without courts; (verso) rough (feint pencil) plan for kitchen offices with the house also indicated, this having a transverse, stretched elliptical centre with the apsidal ends projecting front and back - the first indication of the final plan form and see also verso of drawing 7

5 N^o 3 (Baldwin) and (Bailey) Design for the Entrance Front of proposed House for The Rev^d J. Gooch  showing an elevation for a three-bay, two-storeys and basement house, the salient end bays pedimented, and with a porch on a semicircular plan with four Doric columns; the offices arranged as single storey blocks on each side

6 No 4 (Baldwin) and (Bailey) Plan of the Principal Floor - Design No 4 for The Revd J. Gooche showing a rectangular form with a wide and shallow bow to the garden, balanced by a square-ended projection (the hall) on the entrance front, and with the offices on each side having the same segmental (one-third of a circle) plan with covered passage[s] linking them to the house.  Verso: (pencil) compass-drawn elevation for a ? fanlight

7 (Bailey) Plan of the Principal floor Design No 4 for The Revd J. Gooche.  Almost identical to drawing 6 but with the entrance to the kitchen court omitted and (feint pencil, left-hand side) alternative sketch plan for the offices and (feint pencil, right-hand side) room divisions sketched-in.  Verso (slight, pencil) plan with projecting bows back and front, more detailed than verso of drawing 4 (q.v.), elevations and perspective

8 Copies of three plans, that is, designs 'No 2' to 'No 4' (drawings catalogued as 2,4 and 6) except that: the semicircular courts of drawing 2 are reduced, and the copy of drawing 4 (bottom plan) omits the porch and offices shown on the original plan.  Thus, for ease of comparison, three plans to the same scale (slightly reduced for top and middle plans) are shown in terms of design and importantly of cost: the expensive scheme A at the top, the medium cost scheme B with the possibility of adding the offices at a later stage indicated by dotted lines and, at the end, the minimal cost scheme without offices or porch.  Small (pen) sketch plan for house 

10 Ground floor plan, front elevation and perspective of two-storey with basement and attic, three-bay house with bowed or bombé centre bays at back and front; and side elevation of a three-storey house corresponding with that of drawing 9

12 Plan of The Principal Story, plans to a smaller scale of The Cellar Story and The Bedchamber Story and elevation of the North Front; a kitchen is shown on the left-hand side of the ground floor plan and elevation.  This addition, drawn freehand by Soane, illustrates the unresolved problem of the offices.  Excluding the offices, the design is close to that shown in drawing 11, the house plan reversed as requested in the same drawing

13 (Bailey) Elevation of the Entrance Front corresponding with the elevation of the 'North Front' in the previous drawing except that the first floor window in the bay does not have the relieving arch shown there

14 (Bailey) Elevation of the South Front essentially corresponding with the built design though without the decorations shown here on the windows mullions and the door frame and (verso) rough (pencil) unrelated part plan, rooms labelled Living Room (sic), (of stair) to garret and illegible

15 (Bailey) View of a design for the Parsonage House at Saxlingham, Norfolk corresponding with the north-west view shown in drawing 11 and the elevations of drawings 12 and 13 though without the service wings
