What was once a three-bedroom single floor apartment, has now been expanded upwards – featuring an open-riser marble and glass staircase, connecting its two levels to a mezzanine and roof garden. A zinc-clad bulkhead and central skylight atop its soaring loft ceilings serve to bathe the shared living and dining areas in natural light, and offer glimpses of the lush roof garden above. The now five-bedroom, four-bath duplex is complete with a sixteen-foot-long Corian kitchen island, white marble fireplace, and a walnut wood clad wall with integrated storage, media and pantry functions, running the length of the loft-like upper floor.
