By tossing a teleporter stone as far east as you can (use the shift key to move the screen focus), you can get to the
edge of the map (17KB) and
walk north/south (32KB).
That doesn't get you any closer to the house, but hex editing will.
For
outside the house (68KB), close enough to open the door;
X = 80 76 ;
Y= 90 67 ;
map = 02
Inside the house (49KB), beside the hatch;
X = DC 77 ;
Y= 66 66 ;
map = 02
