What do I have to consider when preparing the building site for a modular house?

When preparing the building site for a modular house, costs for the foundation, earthworks and possible compensation measures must be taken into account. The type of foundation depends on the construction of the modular house. Many modular houses require a solid foundation, while tiny houses on wheels usually only require a small, flat surface. Make sure the building site complies with local regulations and is suitable for the planned house.
