Why use jacks to raise a house from the bottom instead of adding a floor on top? #shorts

why do they want to raise the house from the bottom instead of building another story on the roof this technique is primarily used in situations where a building has settled unevenly tilted or been damaged it can also be applied to move a building once the house is lifted rows of rollers are placed underneath and Jacks are used to apply pressure to the sides of the house allowing it to slowly move the main reason for raising a house from the bottom is to stabilize the structure building directly on the roof could put additional strain on the original structure increas in the risk of damage and uneven pressure could even cause the house to tilt by raising it from the bottom not only can you better control the Tilt but you can also more easily strengthen and reinforce the foundation however not all houses are suitable for this process it depends on the specific situation
