A little while ago, while living in Chamonix, me and a friend decided to build an igloo, there was enough snow around and we didnt feel like catching the bus to go snowboarding, and this is what we achieved, an awesome igloo, good enough to live in, if we didnt have a warm cosy apartment a few metres away.
Step 1: Materials and equipment
First things first, you'l need snow, and lots of it.
And a pair of gloves.
and thats it,
as long as the snow holds together and you can make bricks out of it, then you wont need anything else, maybe a beer or two or a tea and coffee break to warm you up a bit.
