Built at the turn of the twentieth century, it was partly built over the site of the Kensal Green allotments and from the College Road end followed one of the pasts through the allotments.

There was a library in the street which was originally a reading room opened by Mark Twain on 27 September 1900. At the ceremony, Mark Twain gave the Library Committee Chairman five of his books and a signed photograph. By 1904 money from the Andrew Carnegie Trust allowed a proper library to be opened on a site donated by All Souls College. In 1994, the interior was refurbished in a Neo-Edwardian style but the library has now closed.
