The church was designed as a modern Gothic building in early perpendicular style by Arthur Young, a well-known architect of many churches, using St Aldhelm Box Ground stone (from Bath) and flint. It was built by the Buntingford branch of Jacklin & Co under Mr G. Handy, the local manager. The presbytery was built after the nave and sacristy but the whole was completed in 1914.
The foundation stone of this church was laid in the Spring of 1914 and the church, dedicated to St Richard of Chichester (but also officially the Benson Memorial church), was opened on 21st January 1915.
The Lady Chapel, which was mainly financed by an anonymous American lady, was added in 1916. As money was donated, so the building was added to; the porch in 1934 and the tower in 1939. The completed structure was consecrated by the Right Rev. Edward Myers, Bishop of Lamus, on Wednesday 5th June 1940.
The floor of the sanctuary is marble mosaics, while the altar and reredos are of Bath Stone with yellow Sienna marble. There are some interesting stained glass windows with dedications.
In the tower Dr E.C. Messenger, the parish priest at the time, incorporated a piece of marble pavement from the Basilica of St John Lateran, Rome; a piece of stone from the Colosseum; a piece of marble from the Catacombs; a stone from Mars Hill, Athens; stones from the Holy Land, and piece of old wood from St Albans Abbey.
It was hoped also to include a piece of stone from St Richards own Cathedral at Chichester, but in those unecumenically minded days the Chapter of Chichester refused to supply it in return for a piece of the Buntingford church to be built into the new Anglican church in Sussex.
The Great flood at Buntingford on 16th September 1968 penetrated the church and the church and the presbytery to depth of four or five feet, distorting the wood block flooring of the nave and damaging many books and possessions of the priest, Fr.P.Smyth. Later, but not as a result of the flood, the tower needed structural repairs costing some £3000.
