Need to move a house? Here is one description of the process:

First, engineers must assess if the house is structurally sound to move. Once that’s determined, Mr. Davis said, “then physically we come in and typically excavate around the house and clean the perimeter of the house.”
Following the excavation, the next step is to “jackhammer or cut holes in the foundation and slip a grid of steel under the house,” he added. “I have to design the length and weight of the steel to hold the structure without failure. I need to work out weight of structure before I start to position the jacking and lifting points and give my best estimation of what’s necessary to hold the house safely when it’s under my control.”
If the home isn’t undergoing renovations, it can be lifted or moved with household goods, including furniture in place, because that weight is a small fraction of the total weight, which can be many tons. (The furniture does not have to be secured, Mr. Davis said, but he does suggest taking pictures and mirrors down, along with other fragile items.)…
The home must also be disconnected from utilities before the relocation has begun; gas and sewer lines must be cut and capped as well. Once it’s in its new position, they are reconnected.
I have wondered how many houses have been moved in such a way as it would be very difficult to tell after the fact if a home had been moved to the spot.
Many people who have moved might love to hear that this method does not require moving household goods. You can just move your house instead! But, I imagine the cost plus the process – needing to find land, obtaining permits, etc. – make this an unrealistic way to avoid packing.
If the cost of house moving could be reduced, it would be interesting to consider mixing more houses in different locations. In the United States, many residential neighborhoods contain homes roughly constructed at the same time. But, if houses could be more easily moved, there could be more styles and sizes interspersed through residential areas.
