The building consists of a chancel with organ chamber, an aisled nave, a south porch and a tower surmounted by a Hertfordshire spike.

The ones at Wendens Ambo are similar to late Saxon windows in St Bene't's church in Cambridge.

The first church on the site was probably constructed of wood, perhaps as early as the eighth century, but no trace of it remains.

In the 19th century Lord Braybrooke gifted land and a hall neighbouring the church to enable an extension to the ancient churchyard.
