 The building was further enlarged in 1882 by architect Allan Stevenson with the west wing and in 1902 with the addition of the Winter Garden designed by architect Sir John James Burnet.The Pollok Morris family sold the house after WWII to Glasgow Corporation for use as a residential school or 'respite home' for Glasgow boys and later girls.After the school closed in the 1980s the house was vandalised and eventually burnt out with the loss of all the interiors and the portico which had collapsed.
