St Ambrose Church was designed by James Francis Doyle, whose principal area of activity was in Liverpool and the Wirral.
The floor plan of the church is in the traditional gothic style, oriented east-to-west, with a nave and two side aisles, a chancel and an apse-shaped east end.
[1] There are three stained glass windows including one by Caroline Townshend at the west end of the nave depicting Mary greeting the risen Christ, the woman who anointed Jesus' feet with ointment and the widow casting her mite into the temple treasury.
The window in the fourth arch of the south aisle arcade was given by German former prisoners of war in 1947 in recognition of the hospitality of this church to them before their release to return home.
At a later (unknown) date, a lean-to was added to the octagonal vestry to house a toilet and storage for tools for churchyard maintenance.
In 2001 a disabled access ramp in brick and york stone was added to a design by Robin Wolley, architect, of Ruthin.
