Remember to dig based on the excavation area that you received permission to dig in. If you dig outside of that you risk digging into something like a sewer line or a fiber optic cable. Also know what kind of soil you'll be excavating. If you're digging into bedrock you won't get very far.


You also should check your soil records at the town office before you start digging to see what you are going to be digging into and what kind of equipment you will need. Ask the clerk at the town office about your property and they will have the records available for you to see most of the time. If they don't, you might have to have someone come and survey your land.
 It’s incredibly important to know what kind of soil you are working with, and this will also inform your digging strategy. Have a professional come and survey your soil.
 Cut and cover works if you are digging in relatively soft soil. The idea is that you dig out an area, build a concrete structure inside of it, and then cover the hole thing up with dirt again. Obviously you want to keep your hatch or staircase exposed so that you can enter into your structure. However, if your soil will allow for it this is a good way to build a large framework for your home. , This is especially important if you plan to create a berm house. A berm house is a house that is covered by soil but still has windows and doorways to the outside. Your house will sit in a deep foundation and once you have completed the construction of the building you can push the dirt up the sides and on top of the house to create the berm look. This will require a reinforced roof.
Develop a strategy to dig your hole.
Investigate the conditions of your soil.
Consider a cut and cover strategy.
Save the excess soil.
