Make sure to scoop up the snow from the floor as it will give you extra material.
How do you make an igloo roof.
Once complete i cut a small hole in the roof and built a small fire inside the igloo.
The igloo is now 3 weeks old and standing strong.
The entrance should be the last thing you build so work towards it.
Start from the back then the sides that way you dont have a hole in the top of the igloo.
I was able to heat it up to 44 deg f inside.
Cut your trench in a way that places one of its short ends flat against the outer perimeter line of your igloo.
How to build an igloo.

Place them in a circle working your way up.
Don t worry about the floor of the igloo it will collect the extra fallen snow as you build.
Use the snow saw or knife to cut large blocks the harder the snow is the more solid the snow.
Blocks should decrease in size as you work.
The place your trench and outer wall boundaries meet will eventually become your outside door.
The heat melted the inside surface of the igloo slightly allowing it to refreeze and form a strong ice coating.
Smooth the edges of the blocks.
