House built in 1922 with less than 6 ft ceilings. Dug out 100,000 lbs of material and hauled it off in buckets. Took me about 3 months. Now we have 8ft ceilings. Foundation work handled by professional with proper permits.

Would love to dig a bunker in the garden, but the materials to support the walls/roof seem somewhat expensive for just a fun little project. Plus my garden is pretty small so there wouldn’t even be much to it. Like 50m² or so is the entire garden and should probably keep away from the walls of it to avoid undermining someones foundations, that would probably annoy someone.
