Towards the end of his career he incorporated Italianate features, at for example Belsfield, Bowness-on-Windermere, Cumbria (1844) where he included a tower in the style of Osborne House. Webster designed at least 13 new churches and remodelled others; these were always in early Gothic Revival style. Most of his country churches are small, but he also designed three larger churches in his home town of Kendal; of these, St Thomas (1835–37) has aisles and lancet windows, and St George (1838–41) is more ambitious with twin turrets at the west end. Both of these, and most if not all of his country churches, were built for the Anglican church. His third Kendal church, which the authors of the "Buildings of England" series consider to be the best of the three, is the Roman Catholic Church of Holy Trinity and St George (1835–37). Webster also designed public buildings, including the town hall at Settle (1832), the town hall at Kendal (1859), commercial buildings, such as banks in Kendal (1834–35), and Ulverston (1836–38), and the Elba Monument near Burneside, Cumbria (1814). In 1827 Webster married Eleanor Lowrey, with whom he had one son and four daughters. He was involved in the public life of Kendal, serving as mayor in 1829–30. One of his hobbies was collecting Roman coins, medals and antiquities, which possibly developed as a result of his visits to Italy from 1836. In 1845 he took his assistant of many years, Miles Thompson, into partnership, and then he virtually retired from the practice. Webster built his home, Eller How, in Lindale, Lancashire, in 1827 and lived there until his death. He left an estate of "under £25,000" (equivalent to £ as of ). Citations  Sources
