Calm descends as the Palace's imposing wooden doors close.Designed for a government minister in the late 19th century, the address is one of only three houses conceived by Joan Gómez Ripoll - the mastermind behind the famous Gran Hotel Montesol.The building's traditional structure has been catapulted into the present day in collaboration with architect Pascal Cheikh Djavadi. The original soft yellow facade, along with the beams and ornate stone balustrade of the striking lobby, give way to contemporary finishes, sharp angles and a series of streamlined living spaces spread over four floors.Avid bibliophiles will have ample space to house their book collections in the first-floor library, which sits just off the master suite, with white walls and hardwood floors. Its bathroom is a masterpiece of Emperador marble, clad floor-to-ceiling in mesmerizing taupe-colored stone.Avoid the stairs and take the elevator up to the next floor, where you'll find the dining room, with an imposing golden door that pulls back to reveal a minimalist kitchen. Here, light dances on mirrored walls over gleaming work surfaces and Japanese wood cabinetry.At the top of the house, another bright bedroom leads to a sun-catching terrace with sweeping views over the rooftops of neighboring homes.
