The project

The project provides for raising the roof on the east part of the building so as to align it with the west roof of the building, thereby creating an additional storey for the fitting out of two apartments. The change of use concerns only part of the ground floor, formerly used as a restaurant/bar, which will be converted into two apartments and an office, while the rest of the building retains its use. The raised roof will be fitted with three roof windows on the south slope and one roof window on the north slope, ensuring optimal natural light in the future dwellings. The project also includes the installation of a heat pump as well as the application of perimeter insulation on all facades, with a rendered finish, aimed at improving the energy performance and appearance of the building
