The Archers studio
From Tardis Wiki, the free Doctor Who reference
The Archers was recorded in a BBC radio studio. During their eighteen month holiday, the Sixth Doctor and Peri Brown were put in the same location. This led to some discontent; the Doctor had to deliver twelve lambs and twenty-eight calves in just one week and had to do mucking out and corn harvesting as well. Also, a Dalek also made its way into the studio and threatened to exterminate Walter Gabriel. (NOTVALID: Doctor Who? 104)
