The Dutch royal family lived in the house during WW2
The appeal to restore
the stately home in Worcestershire, has passed the £1m mark.
The target for the restoration appeal is to raise £4.8m.
The money raised so far has helped to make the historical landmark wind and water tight, as well as repair the chimneys and flues.
Property Manager Michael Smith said: "The money will enable us to restore the Court back to its 18th century splendour."

The current work taking place is a £59,000 project, funded by the Wolfson Foundation, to restore one half of the north steps, which lead to the front door of the Court and into the Entrance Hall.
The original 18th century balustrade and piers were taken down in the 20th century due to disrepair.
They were replaced in the 1980s by artificial stone, but this failed and the staircase has now been in a state of decay for a number of years.
The mansion house was designed by Capability Brown and Robert Adam, and during World War II was home to the Dutch Royal family.
The grounds were Capability Brown's first landscape project, but have since been cut virtually in half by the building of the M5.
