LL&Co is an architecture and interior design firm based in New York City. 

With discerning sensibilities, the company creates architecture and interiors with understated sophistication and relaxed elegance.  We believe that well-designed spaces do not simply meet the program and functions; they also evoke lasting emotion, manifest rich materiality, and inspire our senses...in other words, the details and matters that enrich our lives.

After graduating with a degree in architecture, Cheng honed tremendous design skills and knowledge through working with various leading architectural and interior design companies in the United States. His experiences include several boutique resorts and hotels, luxury residential development, and single family homes and apartments in the US and overseas.
