 Only a small proportion of Harrison 's work was on churches . In 1804 he re @-@ faced the south side of St Peter 's Church in Chester , and he carried out further alterations to the church in 1813 . Between 1805 and 1806 he redesigned the nave of St John the Baptist 's Church in Whittington , Shropshire , which had been badly damaged in a storm . He did design one new church , the Wesleyan Methodist Church in St John Street , Chester , which was built in 1811 . Although his design was used for the exterior , the internal decoration and fittings were planned by his main contractor , William Cole , and the church has been much altered since . In 1810 came the commission for what is described as " without doubt his [ Harrison 's ] best work at a church " , to rebuild the steeple of the Church of Our Lady and Saint Nicholas , Liverpool . Earlier that year the spire on the medieval tower had collapsed , destroying the tower in the process . The work was completed in 1815 at a cost of over £ 22 @,@ 000 ( equivalent to £ 1 @,@ 470 @,@ 000 in 2015 ) . The steeple has a height of 120 feet ( 37 m ) , its buttresses rising above the top of the tower as pinnacles , the open @-@ work spire being supported by flying buttresses . Harrison also designed a domed ceiling for St Paul 's Church in Liverpool , but this has since been demolished .
