A new Auchans House (NS 36035 34900) was built circa 1819 by Monteaulieu Burgess of Coilsfield, designed by William  Wallace.
Love in 2005 states that the house was in fact built for the Earl of Eglinton and that Burgess was his Commissioner, followed in 1885 by the Hon.
Greville Richard Vernon, son of the 1st Lord Lyveden.
Major Coats of the Paisley thread manufacturers tenanted the house at one time, as did the Beattie banking family.
In 1947 the Earl of Eglinton sold the house to the Earl of Dundonald.
The house was sold by the Earl of Dundonald in 1960 to a builder and then demolished in 1970 and the site has since been developed as a housing estate on the edge of Dundonald.

An Auchans Mains recorded in 1832 by John Thomson lay near Kilnford close to Dundonald and was later renamed as Auchans House; this house now lies under the housing estate.
A place, possibly a farmstead, named as 'Old Auchans' on the OS map (NS 3536 3447) lies as a ruin in the Beech Wood above the ruined Auchans qv 'Auchans Castle.'
The repeated use of the name 'Auchans' has confused the sites over the ages.

The new mansion of Auchans was built in the style of an Italian villa, with projecting glazed porch, giving access to the hall and main staircase.
The land around the house was richly wooded, and this character was carefully preserved, so that from whatever side the dwelling was approached it was against a background of woodland.
The carriage-drive was bordered for a considerable distance with a symmetrical parterre of flowers, and an extensive conservatory formed an exterior wing to the mansion-house.

The principal decoration of the main front wall consisted of the ivy and other trained shrubs.
The mantelpieces and surrounds moved from Old Auchans may have survived as the 1960 sale details specifically exclude these items.
