[1] It was designed by Robert Adam for the owner of Gunton Hall, Sir William Harbord, to replace a former medieval church.
[2][4] St Andrew's is constructed in gault brick, parts of which are rendered, with stone dressings.
It is in the form of a temple with a tetrastyle (four columns) prostyle (protruding forward) portico.
On both the north and south sides are four niches, three square-headed windows, a plain architrave, rosettes in the frieze and dentils in the cornice.
On the east side are three blank rectangular panels, the central one with a memorial tablet inscribed with the date 1665.
The other door leads into the church, which is paved in stone with black diamond-shaped inserts.
