St Andrew's was the first Presbyterian church to be built in Christchurch (1856-1857). It was designed by H.J. Cridland (1823-1867), who was probably the first architect to work in Canterbury. Cridland arrived in Wellington in 1843 and was employed in the Colonial Survey Office. He designed a number of buildings in Wellington including St Peter's Church (1848) and the Hutt Anglican Church (1849.) In the middle of 1849 Cridland moved to Lyttelton to become the Superintendent of Public Works for the Canterbury Association. Although working primarily as a surveyor, he possibly designed and certainly supervised the construction of various buildings for the Canterbury Association in Lyttelton. According to art historian, Jonathan Mane-Wheoki, St Andrew's appears to have been the last building Cridland designed. St Andrew's opened for worship on 1 February 1857. At this stage the wooden building was only 54 feet by 22 feet (about 16.5 m x 6.7 m) and stood at the intersection of Tuam Street and Oxford Terrace. Around 1862 a nave was added. At this time the original building was divided and became the transepts of the enlarged church. In 1892 St Andrew's was enlarged and extended again so that the original 1857 building became contained within the transepts of the 1890s church. This extension/reconstruction of the main portion of the nave and the west end of the church, with its distinctive wheel window, was designed by R.W. England. England later joined forces with his brother to form the Christchurch architectural firm England Bros, which became well-known for both domestic work, such as McLean's Mansion, and commercial buildings, such as the former D.I.C. building in Cashel Street. With the growth of the surrounding suburbs from the 1920s, St Andrew's congregation began to dwindle and the church was no longer the centre of Presbyterian worship that it had once been. By the 1980s it was marooned in the middle of a commercial area and the congregation had become so small that the future of the church was in doubt. At this time Rangi Ruru Girls' School was looking for a new school chapel, and in 1986 St Andrew's was cut into sections and transported across town to its present site at Merivale Lane. It reopened in 1987 and now functions both as the school's chapel and a parish church. Historically the church's significance lies in its connection with the early Presbyterian Church in New Zealand. It is also associated with the first Pakeha to settle permanently on the Canterbury Plains, the Deans family, who were closely involved with the establishment and congregation of St Andrew's. Architecturally St Andrew's is significant as a rare example of R.W. England's ecclesiastical work in timber.
