In major building works in the 1980s, the BBC Architectural & Civil Engineering Department restored the old interior, removed utilitarian brick buildings put up alongside the east side of the mansion during the war, converted the existing orangery for use as a canteen and editorial offices, and built a large new two storey west wing housing the listening room. This included a new glazed atrium facing the original stable block. A further major building project in 2007–08 saw the west wing converted to house all of Monitoring's operational staff.
