Teorema Milanese apartment, designed by Marcante Testa.The studio was keen to maintain the apartment's classic layout and thus decided to make just one significant structural change,a partition wall has been knocked through to form an open-plan living and dining room.

Pale grey cipollino tirreno marble becomes a "carpet" in the sitting area, which is dressed with sculptural armchairs, a khaki-green leather sofa and an oversized floor lamp.The marble also extends up part of the wall and ceiling to create a giant window frame that looks out over a tree-lined boulevard below.

The design of the marble slabs and the pattern of the veins within them create visual pathways, guiding the inhabitants through a pattern of precise spatial hierarchies,Deep-green verde alpi marble then covers the floor and sideboard of the other half of the room, which is centred by an oval, timber table.

Adjacently lies a brass-framed screen that offers a sense of separation between the dining area and the apartment's entryway.It's inbuilt with a diamond-shaped mirror and a lemon-yellow cabinet where inhabitants can stow away their belongings.

A long central corridor leads off to the home's other brightly hued rooms, which are partially concealed by panels of mottled glass with coral-orange borders.Maroon-streaked salomè marble serves as a splashback to sinks in the bathroom, complete with jet-black tap faucets.

Meanwhile, in the kitchen, sea-green cabinetry complements geometric floor tiles that appear in the adjoining breakfast nook. Leaf-print ochre wallpaper runs across the ceiling above.A similarly clashing mix appears in the master bedroom, where heavily-patterned wallpaper has been paired with flecked blue wardrobes and sheer polka-dot curtains.
