St Augustine's is a large church which is only half the size it was supposed to be. Consists of a wide nave, with walled choir and semi circular apse (polygonal on the outside).
Inside contains four different artworks by Fleur Kelly in the Byzantine style including the magnificent apse ceiling of Mary, Christ in Majesty and St Augustine painted in egg tempera and surrounded by two types of gold leaf. She also painted two large icons and two triptych's. There are several stained glass windows including on to the south of the choir by Basil Barber, and apprentice of Sir Ninian Comper.
The font is a replica of the Norman font at Stanton Fitzwarren and is surrounded by statues of representing the goodly Christian virtues stamping on the evil vices. Sir John Betjeman was said to be a regular visitor to evensong and is know to have visited the church on several occasions.
