It is a neoclassical building designed by the architect Henry Hakewill with a hexastyle portico with Ionic columns and a clock tower.

The interior was, as was common at the time, a "preaching box", with galleries in three sides and the organ and choir at the west end.

[2][5] In 1875, the church was enlarged and reordered to designs by Sir Arthur Blomfield, who added a chancel at the east end and north and south transepts and "fiercely normanized" the interior.

[6] Internally Blomfield's chancel and transepts are Romanesque Revival, but externally they conform with Hakewill's neoclassical style.

On 20 October 1987 an anti-Catholic arsonist set fire to the east end, in the mistaken belief that the building was a Roman Catholic chapel.

The Braithwaite Partnership of architects was appointed to completely redesign the building[11] with a new and simpler interior, and to incorporate within the site a vicarage, offices, flats for a curate, verger and music director, a meeting hall, nursery school rooms and a large playroom for the church's youth club.
