The fuselage of Me 262A-1a WNr 170072 was found together with P.1101 at Oberammergau. The terraced area can be noticed here:

According to the reports I have linked, Oberammergau in 1943-45 was overcrowded with Messerschmitt personnel and forced labour workers so the barracks certainly havenīt been sufficient. Additional buildings may have been erected when an airfield was built (n.b. with an airstrip long enough for the Me 262!)
