Our curiosity was aroused by this house, set at an angle to the road, and with the appearance of a cottage, in comparison to the other buildings around.

Designed by Richard Norman Shaw this house was built in 1878 for the artist Matthew Ridley Corbett (1850–1902). Google Satellite View shows that, in the attic room, the house has that item essential for artists at the time, large north-facing windows. After Corbett the house was occupied by the artist Frank Dicksee (1853–1928). Flint lived here 1925-69.

Immediately to the west is the massive 118 Campden Hill Road which was built at the same time, also by R. N. Shaw, for the artist G. H. Boughton (1833–1905).

These maps and quotes from British History Online tell the story of the site:

The 1863 map shows "eight {actually 7 and a half} pairs  of semi-detached cottages called Claremont Place, which were among the first houses to be erected in the street {Peel Street} and were completed by 1826."

The 1893 map shows the next development: "... 1877–8 ... Campden Houses, No. 80 Peel Street and No. 118 Campden Hill Road were built in place of the sixteen semi-detached houses which Punter had sold to John Herapath in 1829. The seven blocks of flats called Campden Houses ... were built as labourers' dwellings for the National Dwellings Society Limited .... The Society's architect was E. Evans Cronk. ... No. 80 Peel Street was built for Matthew Ridley Corbett, the portrait and landscape painter, who had purchased the site in 1876."

Compare the 1893 map with the Satellite View and one can see that there has been substantial infilling on the site.

These houses and their residents were part of the informal Campden Hill artists colony.
