Hove's first Roman Catholic church was the Church of the Sacred Heart on Norton Road. Early in the 20th century, its priest paid £600 for a plot of land on Portland Road—a main road running westwards from Hove towards Aldrington and Portslade—with the intention of establishing a new church there. A hall, dedicated to St Peter, was built on this site in 1902, and Mass was first celebrated there in 1904. It was part of the parish of the Church of the Sacred Heart. An architect called Dixon submitted plans for a new church in 1912; in September of that year the local Council granted permission for building work to begin, but his designs were abandoned and a different architect, Claude Kelly, was chosen. He submitted his own design in 1913. A new priest was appointed in 1915, and he raised £9,000 towards the building of Kelly's church. It was finished in August 1915. Claude Kelly's father John, who had designed dozens of churches in his architectural career, is believed to have been involved as well—he had been in partnership with his son since 1904—and another ecclesiastical architect, J. Marshall, may also have worked on the building. St Peter's was not consecrated until 28 June 1927, after improvements were made to the internal fixtures. The original pews and pulpit were replaced in 1929, and a parishioner provided the church with an organ made by Henry Willis & Sons. The church is licensed for worship in accordance with the Places of Worship Registration Act 1855 and has the registration number 40697.
Architecture
The church is built of red brick in a stretcher bond pattern. The roofs are of slate. The nave has six bays and north and south aisles; the latter has three side chapels, and there is also a Lady chapel with a round roof and two lancet windows. The chancel and apse have a similar roof design. A presbytery adjoins the northeastern side, and at the opposite corner is the building's landmark—a tall campanile with bell-chamber and copper roof. The entrance, flanked by pilasters, is at the west end below a rose window. Described as "startling" by English Heritage for its similarity to an Italian-style basilica, the church is also considered to have an impressive interior; there is much use of marble in various colours, and a barrel-vaulted ceiling. In 2019 the plain glass in the rose window was replaced with a new rose window designed by DTForsdyke and created by DTForsdyke & Silver Stained Glass. The window was commissioned to celebrate the centenary of the church.
