Architect Charles Busby planned and built the Brunswick Town estate, which (together with other nearby residential development) helped the population of Hove to rise from 100 in 1801 to 2,500 in 1841.

Everard was granted an Act of Parliament on 3 April 1828 giving him and his successors ownership of the church, the right to appoint a curate for the next 40 years, and two-thirds of income from pew rents and other sources.

[7] St Andrew's immediately became popular with the fashionable set, helped by the regular presence of members of the Royal Family and the aristocracy.

[8] A more radical change took place in 1882,[2] when the church was extended at a cost of £7,000 (£2,000 to buy and demolish an adjacent stable block and £5,000 for the construction work);[3][9] Charles Barry's son Edward Middleton Barry added a chancel, a sanctuary with Ionic columns, an illuminated dome and space for an organ.

[1][3] The decline had set in several decades earlier, and the Diocese were considering demolition; the granting of Grade I-listed status on 24 March 1950 meant this could not happen.

[8] Squatters caused damage during the 1990s,[10] but restoration work in 2001 and 2002, costing more than £100,000, allowed the building to be reopened for occasional services, special events and community activities.

[2][5][7] Originally, the interior was less grand, with no chancel, simple pulpits and a single gallery,[7] making it a plain, box-like preaching-house.

The entrance door is set beneath a round-headed arched opening between twin pilasters, the outer pair of which serve as quoins for the adjacent recessed walls.

Five, including memorials commemorating Lord Charles Somerset and Sir George Dallas, 1st Baronet, remain in the nave, however.
