In order to raise a house, some conditions are needed.

First of all, the national laws that govern the territory, the regional urban planning instrument and the local building regulations must allow this building activity with a procedure such as the SCIA edilizia or the PERMIT to BUILD.

Therefore, the natural or legal person who wants to make this assessment must contact a professional in the sector, registered with the professional association, to obtain a preliminary opinion on feasibility, after having assessed the legislative feasibility, we move on to the executive feasibility.

This type of intervention is often carried out on buildings that are part of the existing heritage or in most cases load-bearing masonry buildings. The technician must carry out considerations and tests aimed at understanding whether the existing building is suitable at a static and seismic level to receive and support an additional living level starting from the analysis of the foundations, floors and load-bearing walls.

If favorable feedback is obtained, evaluations are made on the best technical solution to adopt for the elevation.

Usually, to create the least static burden on the existing structure, solutions with a load-bearing structure in steel and/or wood are preferred.
Even the external and internal infill walls can be made with light wooden panels with plasterboard covering or with walls with a metal structure always covered in plasterboard.
Finally, thermal insulators, which can be of natural or synthetic-industrial origin, allow the thermo-acoustic insulation of the building.

In fact, suitable products are laid on the external walls of the building that make up the thermal coat and the rough or smooth finish typical of plaster.
The thermal coat in the elevation phase can also be extended to the remaining part of the building to obtain overall energy efficiency.
