Artists Lisa Yuskavage and Matvey Levenstein's Upper East Side apartment had been previously renovated in a 1990s architectural style, with oddly curved walls and dated door details. The pair stressed the importance of living amongst their own deeply personal artworks, so we bathed the apartment in tranquil shades of gray to ensure that the paintings were the stars of the show. The furnishings complement the gray-on-gray palette, accentuating the mood of contemplative repose. Sparingly deployed, signature pieces by Pierre Paulin, Maria Pergay, Achille Castiglioni, René-Jean Caillette, and Giovanni Offredi offer sculptural integrity without disrupting the space's serene composition — an aura of calm animated solely by the play of natural light across surfaces and materials.
