Located on the 39th and 40th floors of one of the tallest mixed-use skyscrapers in New York City, this duplex has edgy yet sophisticated interior. Designed by Axis Mundi Design, this project has many impressive features, such as attention to detail, careful selection of artwork, daring use of color, and integration of material and texture. But one of the most daring decision is the leather walls that distinguish the social areas of the household. Besides that, the same leather is introduced on the handrail of the dramatic feature staircase.
