Philip Mainwaring Johnston

Philip Mainwaring Johnston (1865–1936), also known as PM Johnston, was a British architect and architectural historian.

Education Philip attended King's College School, London. He studied drawing and painting under Professor Delamotte at King’s College, London. Professor Delamotte was a photographer/illustrator who became Professor of Drawing and Fine Art at King’s College. Whilst studying at King's College, he undertook many sketching trips in England and on the Continent - an important part of every architect's education at that time.

He designed several new buildings, mainly in the Home Counties, including churches, houses, vicarages and model cottages.

Philip was the seventh of twelve children. His brother was Sir Henry Hamilton (Harry) Johnston, a British explorer, botanist, artist, colonial administrator, linguist.

PM Johnston married at Yapton parish church, Sussex, on 3 September 1902, Florence Anna Wynne, third daughter of the Right Rev. Frederick Wynne, Bishop of Killaloe and Clonfert.

Their daughter was Thea Holme (1904–1980) who was an actress in the 1930s and later a writer.

He lived in Camberwell on de Crespigny Park (from 1907) and at Sussex Lodge, Champion Hill, Camberwell (now No. 42 ) from 1914. The latter was one of two pairs of semi-detached houses that he designed and built in the arts and crafts style. All four houses remain and are perhaps the best example of the arts and crafts style in the local area.
