Troutbeck Park Farm, Troutbeck in the Lake District National Park, Cumbria.
The farm was bought by Beatrix Potter in 1923. In 1926 she decided to run the farm herself with the help of the shepherd, George Walker, brother-in-law of Tom Storey who ran her Hill Top Farm in Near Sawrey. Beatrix built the neighbouring detatched house for the shepherd to live in.
The farm and its large herdwick flock were left to the National Trust upon her death in 1943.
