The apartment is set within a 200-year-old palazzo in Brera, fronting the same courtyard as Salvatori's Milan showroom, where the brand sells a variety of natural stone tiles, furniture and homeware.
Having grown tired of the apartment's characterless white surfaces and fixtures, brand CEO Gabriele Salvatori tasked designer Elisa Ossino and her eponymous studio with giving the space a more intimate feel, so he could entertain friends and clients "in a more convivial context".
"It was a great opportunity to show and experiment with the use of Salvatori's beautiful marble collection in a domestic environment," Ossino told Dezeen.
"I wanted to design an interior that was able to fully tell the Salvatori story, deeply connected to marble manufacturing."
In the living room, the old a partition wall and false ceiling were knocked through to give the illusion of more space.
Ossino introduced coloured pieces of marble to form large decorative artworks, displaying an assortment of three-dimensional shapes.
There are also a selection of pieces by Salvatori scattered around the room's off-white sofa and wicker armchairs.
These include the Colonnata oak bookcase, which features veiny marble shelf dividers, and a series of vase-like marble ornaments intended to echo those seen in the still-life paintings of 20th-century Italian artist Giorgio Morandi.
Hues seen in the apartment's original ripple-pattern terrazzo floors are applied throughout the interiors. In the dining area, which is centred by a monochromatic marble table, walls are painted dark grey and the ceiling is blush-pink.
Slate-coloured marble tiles line the walls of the bathroom, while bolder tones feature elsewhere – from the golden corridors, to the teal-hued master bedroom.
"The dialogue between marble, colour, and the existing floor looked extremely interesting to me," explained Ossino.
Founded in 1946, Salvatori is one of Italy's leading manufacturers of stone and marble, and has previously worked with architects and designers including John Pawson.
This project taps into the trend for making clever use of marble in home interiors. Other examples include a flat in Portugal with a peach-toned marble bathroom and a penthouse in Belgium with a marble partition wall.
