At Arthaus, reclaimed wood runs through every room, giving unity to an apartment designed to house an art collection that spans centuries and styles. In the entrance hall, a black door with visible pores leads to a dark space where a classical sculpture, once in the garden of the previous house, takes center stage under the light. In the living room, a grand piano, a Baroque work by Aleijadinho, and the Papa Bear armchair share the same space without competing: the neutral base, in white lacquered wood with discreet boiseries, exists so the pieces speak first.

In the dining room, a solid oak table, once a sewing counter, carries the weight of history alongside a lighter, more recent Calacatta marble counter. On the balcony, a silver travertine table designed by Two shares space with a coffee table carved from a single log. In the bedrooms, warm gray tones and green leather mark the private wing, and the powder room, clad in Nero Marquina marble with a brass-framed mirror, closes the apartment like a small gallery of its own.
