Sir Joseph Boehm, from Aitchison's designs. The capitals of the large columns, gilded and carved in the shape of birds, are by Randolph Caldecot. The mosaic frieze was designed by Walter Crane. The marble work was by George P. White. Elaborate decorative paintwork adorns the domed ceiling and in the centre of the floor there is a fountain. The tiles in the passage to the Arab Hall are by William De Morgan. In 1889 an additional winter studio was added to the building. The final addition by Aitchison was the top-lit picture gallery in 1895. After Leighton died in 1896, the contents of the house were sold, including at least one thousand of his own drawings, almost all of which were bought by the Fine Art Society. In 1927 Mrs Henry Perrin offered to pay for additional gallery space. The building was extended to the designs of Halsey Ricardo and the Perrin Galleries opened in 1929. This extension was in memory of Mrs Perrin's daughter Muriel Ida Perrin, an artist and sculptor who had trained at the Royal College of Art and worked for the catalogue section of the Aircraft Manufacturing Company (Airco) during the First World War.
