Cumberland House

Cumberland House was a mansion on the south side of Pall Mall in London, England.

It was seven bays wide with three main storeys plus basement and attics and was built of brick with stone dressings.

He built a projecting west wing on the site of a neighbouring house that he purchased and added a pair of lodges flanking the forecourt, probably all to designs by Robert Adam.

Adam also made many designs for remodelling the interiors, which are now in the collection at the Sir John Soane's Museum, but only a few of them were carried out.

The Duke of Cumberland died in 1790, and in 1800, the widowed Duchess surrendered it to the banks who held mortgages on it.
