It's a Pub - Mags' House.

So yeah...I realized with Mags, Pietro, Wanda, and Billy in one house, with an open invite for Tommy to live there if he wants to live with his brother, and for Lorna to crash anytime, as well as Charles, Rissa, and Jean being able to come over any time (as well as TJ, the young Wanda, and any other person Magneto is related to *period* when he finds out about them) it might be a good idea to have IDK, a floor plan of this house.
