On January 10, 2020, Walker announced "The Bunker" which were new facilities serving as the headquarters and office for his Mr JWW (James Walker) YouTube channel. The facilities are part of a refurbished Royal Air Force base built during World War I.

The new space allows Walker to do more in-depth reviews of cars and is also accompanied by a private race circuit allowing him to test the performance of cars in more detail than before.

The first car Walker reviewed and tested as part of the new initiative was the Koenigsegg Regera. ^[15]
