The building was heavily modified in 1845 either by another local architect, John Billing (according to the list description),[1] or a William Webb (according to the Jesuit priest and architectural historian Anthony Symondson),[3] when it acquired its current high-pitched roof and façade.

[1][4] The architectural historian Gavin Stamp described it as a "dull Gothic box"; but it was one which the Vicar from 1967 to 1989, Brian Brindley, greatly enlivened.

[5] The chancel screen in the Church was designed by Augustus Pugin and had originally been installed in St Chad's Cathedral in Birmingham.

Other items included a Martin Travers high altar (in the form of a gilded sarcophagus), designed for Nashdom Abbey, which Brindley installed in the Lady chapel.

[10] The church appeared in one of the earliest ever photographs by Henry Fox Talbot whose Reading Establishment was located nearby.
