The east end was inspired by the German Cistercian church of Heisterbach on the request of the vicar, the Reverend Frederick Hall, who had formerly been curate at St. Augustine's, Kilburn, another of Pearson's celebrated works.

[1] The church comprises an apsidal chancel with ambulatory and south chapel, two north vestries, an aisled and clerestoreyed nave, and a western narthex or baptistery of one bay.

The stained-glass panels are by specialist firm Clayton and Bell - the east windows depicting the adoration of the lamb, the south picturing angels, bishops and St Paul preaching, and the north Protestant worthies.

The chancel windows are also a memorial to the Reverend Prebendary Frederick Hall,[6] rector of Friern Barnet, by whom the building was commissioned.

[7] The church has since been afforded Grade II* architectural status[8] by the English Heritage foundation, by which it is deemed a building of particular (national) importance and one of more than special interest.
