I made this house using powershell for the creation. It is almost at the limit of the command block. To install place a pulse-commandblock while facing north. Copy paste the code into it and place a button on the block. You should arrange a 25 block that is 'flat' with the level of that command block to its north for the other blocks to fall on. The structure will be build to the north and to the east (your right). Best test this on a superflat test-world before using it in your world. It is quite big and could overwrite your own structures otherwise.
The build is not finished and definetelly needs more lighting to be safe. You need to bring torches, a door, a pickaxe and a bed. Otherwise it is a solid and relatively safe house with lots of room for your stuff.
