Having been articled to his father and to E. W. Mountford, of Lower Regent Street, London,[7] and studied design under William Bidlake at the Birmingham School of Art,[8] from 1866 he worked with his father, and in 1897 became a partner in the firm, J. A. Chatwin & Son. From 1936, Philip's nephew Anthony Chatwin was his partner in the business. The repair of churches was a speciality.[9] In 1911 he designed the new building for King Edward VI Handsworth School for the head Margaret Nimmo who was moving with her school from Aston.[10]
An enthusiastic archaeologist and local historian, he was elected a Fellow of the Society of Antiquaries. He also sat on the Council of The Royal Archaeological Institute of Great Britain and Ireland from which he retired in1943.[11] He was honoured with a festschrift by Birmingham Archaeological Society[12] and, after his death, the Society recorded that it had lost "the last and one of the most active and distinguished of its founder members", and that he had "for the greater part of this century, embodied the history and antiquities of the County of Warwickshire".[13][14][15] He was appointed OBE in 1953, for archaeological services to the Ministry of Works.[16]
As well as writing a number of articles for journals such as The Antiquaries Journal[17] and many for the Birmingham Archaeological Society Transactions,[18] he was the author of the book The Medieval Patterned Tiles of Warwickshire (1940) and editor of The Records of King Edward's School, Birmingham (1948). His writings are often still listed as recommended reading, for example, a number of his articles, including 'The Decoration of the Beauchamp Chapel, Warwick, with special reference to the sculptures' in Archaeologia, LXXVI, 1928, are included on the ‘Gothic Reading List’ of the Victoria and Albert Museum, London[19] and, not unsurprisingly, reflecting his love of his home county, works by him are on the recommended reading list for Warwick University’s History of Art course, Special Studies in Historic Architecture.[20]
Apart from his research findings which continue to be cited (see footnotes below for examples),[21][22] Chatwin’s legacy is remembered in other ways; photographs and plans are held by Birmingham: Archives, Heritage and Photography Service,[23] Warwickshire County Record Office[24] and The Library of Birmingham[25][26] and working papers of the scholar Gordon McNeil Rushforth, held in the University of Exeter archives, include correspondence with Chatwin.[27] Photographs attributed to Chatwin, including images of the interior of Beauchamp Chapel, St Mary’s Church, Warwick which he researched and wrote about extensively, are held by the Conway Library, whose archive, of primarily architectural images, is in the process of being digitised under the wider Courtauld Connects project.[28]
In 1906, Chatwin married Cecily Frances (1882-1968), daughter of chartered surveyor and land agent Robert Edward Couchman, of Birmingham, of a gentry family of Solihull They had no children.[31]
The Church of St Augustine of Hippo, Edgbaston (porch and door on south aisle erected, and a new door opened from the choir vestry into the church, 1907). To celebrate the church's centenary in 1968, a new narthex porch was added at the west end to an earlier design by P. B. Chatwin.[33]
