Compared to a normal floor slab, the average extra cost for an additional basement is between 300-400 euros per square meter. If skillfully designed, the approximately one third larger floor space can even help in financing the home, because: if part of the added floor space is considered "living space," government aids can be used to the full. Large acclivities or elevated basement studios can be used as an extra apartment, contributing to the financing of your home. In relation to the building costs, a basement can improve the growth of the house value, since the resale value usually increases significantly. Technical aspects underline the benefit of basements. From a construction standpoint, there are considerable disadvantages if you build a house without basement.
For example: House connections and the maintenance of fittings are more expensive, sound insulation of town houses and duplexes is inferior, cohesive soils beneath the foundation can dry out and shrink, the floor slab can sink, causing the walls to fracture and utilization of small lots is vastly inferior.
