Build a semi buried house on a hillside
[1] cut away hillside to get level building area
[2] put in pile and raft foundations
[3] build walls of cellar
[4] replace earth around cellar
[5-->] complete house
only at stage [3] the keen DIYer put all the materials in the centre of the foundation slab and built the cellar walls from the inside working on step ladders.
And with no door opening in the 9 foot high walls he was trapped inside.
""I didn't want to climb out until the mortar was set""
As this was in New Zealand's summer the night wasn't too uncomfortable.
