Penthouse

The scope extends throughout the penthouse, from the floor-to-ceiling bookcase and operable bar in the living areas to the kitchen, walk-in closet, office bar and custom bathtub. Metal is the recurring thread, but each surface is treated differently: mirror-polished stainless steel, natural and waxed brass, galvanized copper and antique-effect finishes shift the mood from one element to the next. In the living room, 3TO5 fabricated a self-supporting stainless-steel bookcase with a mirror-polished finish and integrated fireplace cavity, while the nearby operable bar pairs a wood-and-metal structure with an illuminated pink onyx panel. The result is a layered material language where reflective, aged and translucent surfaces give each custom piece its own character while maintaining continuity across the residence.

The eat-in kitchen was executed in natural brass using traditional Italian techniques. Four wall cabinets in waxed brass were joined by welding and then polished directly on site, allowing them to read as a continuous architectural surface rather than a series of separate units. That same attention to fabrication extends to the custom bathtub, which was calendered, welded and polished on site before receiving a galvanized copper finish. In the primary bathroom, a one-piece iron vanity was finished in gunmetal, paired with a custom wood-veneer closet.

For the walk-in closet, 3TO5 produced stainless-steel shelving and shoe storage with integrated LED lighting. The office bar shifts again in tone, combining a solid wood structure with custom galvanized brass developed to achieve an aged appearance. Across the penthouse, the project becomes an exercise in how metal can change through finish, technique and context: polished until almost immaterial, aged for warmth, or combined with wood, stone and light. The complexity lies in the fabrication; the finished interiors make it appear effortless.
