"House 1" is 'north' of spawn (you spawn on an island)
I have made a pathway/road over to a underground path, which leads to "House 2" where I ended up after some flying around, and got lost :-)

after grabbing REI's map mod, and some more flying around (this time making a few WAYPOINTS!!!) I was able to locate where things were a bit better...

so - I dropped back over to house #2, and thought I'd run an underground path/tunnel most of the way over to house #1... you can see the close to 1000km long tunnel if you turn on caves, and look for the path going east/west from house #2 (House #2 was in the far 'west' in the frozen area)

there are a few animal pens over there as well as a partial dirt house, that I was using as a base while in survival mode.

if you like the seed, or find anything cool, please feel free to share x/y/z coordinates, and I will look into whats going on out that way...

oh one last thing - there *IS* a hole in the bedrock under house #1... so please be careful - I was doing a bit of digging, and well, fell out of the world - oops!
