The real estate complex known as Podere Derna, consisting of five real estate units, is west of the town of Stigliano. The units have been restored after decades of neglect and decay to be used as private residences. The restructuring that affects the building complex as a whole consists in the recovery and restoration of the original surfaces and volumes through the strengthening of the vertical wall structures, the construction of a new attic floor and roof, total refurbishment of the roofs, the installation of modern sanitation systems, and the installation of energy-saving, high-tech thermo-hydraulic and electrical systems.
