It was originally associated with the chantry chapel in the nearby parish church of St Boniface, founded by Sir Ralph Egerton.

The Chantry House is an early surviving example of a residential timber-framed building in Cheshire, with many typically medieval features.

"[1] Sir Ralph Egerton (also Raufe or Rafe; before 1476–1528) – standard bearer to Henry VIII, who awarded him the nearby manor of Ridley – commissioned a chantry chapel to be added to St Boniface's Church in Bunbury.

The chantry (known as the Ridley Chapel) was begun by 1527, but remained incomplete at Egerton's death in 1528, and was finished under the provisions of his will.

"[6] According to Egerton's will, the Chantry House was to be constructed with stone and roofed in Welsh slate, and was to have two rooms, a parlour and a buttery–kitchen.

[5][8][10][11] Aldersey gave the grammar school to the Worshipful Company of Haberdashers, of which he was a prominent member.

[10][12] Among the school's endowments was the 2000-year lease to its governors, dated 31 March 1595, of the Chantry House, together with other land and properties in Bunbury, for "the rent of a red rose".

[1][3][5] The Chantry House is located at SJ5683757958 on Wyche Road in Bunbury, Cheshire, immediately south of St Boniface's Church.

[3] The original three-bay, two-storey, timber-framed house rests on a sandstone plinth, with a slate roof.
