IGLOO BUILDING

Make an Inuit shelter with our survival feature

1 CUT BUILDING BLOCKS

Cut blocks from hard, dry snow about a metre wide, 40 centimetres high and eight centimetres deep.

2 SURROUND THE HOLE

Cut a circular groove around the hole you’ve just cut the blocks out of, deeper at one end than the other.

3 PILE UP THE BRICKS

You can now stack up the snow bricks in a continuous spiral, overlapping so that they lean inwards.

4 MAKE AN ENTRANCE

Cut a tunnel under the wall on one side. As well as being a way in, this traps cold air.

5 FILL THE HOLE

Put the last block on top of the igloo. It will be larger than the hole, so needs shaping.

6 FINISHED IGLOO

The finished igloo is warm – so warm it needs ventilation holes to avoid it melting.
