Inside the stunning County Durham country mansion with tennis court and private gym

A remarkable Grade II-listed country house set within more than four acres of immaculate grounds is on the market in one of County Durham's most sought-after villages.

The Cottage, on the edge of Castle Eden, offers nearly 10,000 sq ft of living space and has remained in the same family ownership for more than 60 years.

The house was once part of the historic Burdon Estate and dates back to the late 1700s, with later additions creating a distinctive home.
