It is built of timber, and has two storeys, the upper level being supported on joists and brackets carved as "fabulous beasts".

[a][2] A survey undertaken in 2007 by the Canterbury Archaeological Trust noted the traditional theory that All Saints had been built as a row of up to six independent cottages but discounted this as unlikely due to the existence of a single staircase linking the lower and upper floors.

[5] The building comprises a two-storey range, the upper floor extending over the street and supported by joists with corbels elaborately carved in the forms of "fabulous beasts".

[b][1] A staircase leads from the lower to the upper floor, which consists of a single room, 77 ft in length.

[2] The trust's 2007 report indicates that the upper storey was originally subdivided, although interconnected, and suggests that it may have initially been used for storage, with the ground floor functioning as a row of shops.
