 The mansion was subsequently enlarged, with an extension to the south in 1929 followed by one at the north end of the house in 1935, resulting in loss of the portico facing Southgate Green, and encased in red brick.The house was sold to Legal & General in 1975 and renamed Southgate House (not to be confused with Southgate House).In 1997-8 the bulk of the property was converted into a residential care home called Southgate Beaumont with the southern part developed into luxury apartments.
