String courses separate each stage and a battlemented parapet forms the top of the walls on each side.

The external walls of both aisles are buttressed and have a moulded stone plinth and a string course topped by a battlemented parapet.

The aisles are divided from the nave with arcades of four pointed arches with octagonal columns and moulded capitals and bases.

The aisles have shallow lean-to roofs, but evidence internally suggests that these were steeper before the 15th century.

In the centre of the south aisle, the lower 15th-century porch contains single windows in the east and west sides and a battlemented parapet.

[1] The chancel is flanked by chapels on each side, divided from them by arcades of two pointed arches, again with octagonal columns.

[1] The church contains a large number of memorials to members of the Filmer family former owners of the adjacent house of East Sutton Park.
