THÜRINGEN

"Kernsaniert" means that a building or apartment has been extensively and thoroughly refurbished, with both the exterior and interior structure modernized and improved. During a complete renovation, essential elements such as electrical systems, plumbing, heating systems, windows, doors, insulation, and often the layout are renewed or brought up to current standards.

The goal of a complete renovation is to elevate the condition of the building to almost new construction level, making it modern in terms of energy efficiency, functionality, and aesthetics.
