The last example of Lombard fifteenth century in Varese, Casa Frasconi (located in the street of the same name in the Biumo Inferiore district) risked collapsing under the weight of neglect. The building, which is spread over three floors including the ground floor, with a broletto, features original plaster and stratigraphy of decorations that occurred from the 15th to the 19th century. Cores4n is regenerating this incredible place to restore its beauty and function to new generations. A regenerative process that looks at our historical heritage not with immobility, but with a vision inspired by sustainability and aesthetics, to connect it to the comforts and inclusive capacity that places to live in the third millennium must have.
