Tailored interiors with timeless appeal

HCO Interiors designs homes with presence - refined, deeply personal spaces that feel effortless to live in and impossible to forget. Our work is rooted in the belief that true luxury is not about excess, but about intention: homes that function beautifully, feel quietly elevated, and reflect the people who live within them in a way that feels both authentic and aspirational.

Creating spaces you’ll never want to leave

Luxury interior design by HCO Interiors featuring bespoke residential interiors, custom furnishings, modern living spaces and full-service interior design in New Jersey and New York.

A personal approach

About HCO

Every project is approached with a fresh perspective, balancing understated sophistication with bold restraint, layered materiality, and unexpected details that bring depth and individuality to a space. The result is a home that feels collected rather than decorated; polished, intelligent, and entirely your own.

Known for bringing a modern sensibility to suburban living, HCO Interiors creates environments that are as functional as they are refined. We obsess over how our clients truly live: the routines, the rhythms, the moments that happen behind closed doors. Through thoughtful layouts, tailored details, and highly considered design decisions, we transform everyday living into something seamless, elevated, and inspiring.

  • Hillary made the vision for our mudroom addition come to life. She was incredibly thoughtful with every aspect of the space, from the design of the room down to the details on where the hooks were placed. I can't wait to see what she does with the rest of our home. We're so grateful to work with Hillary.

  • Hillary was extremely helpful in planning, sourcing and ordering for my new apartment. It ensured for a smooth move, especially as I was unable to dedicate time to shop for interiors myself. She really listened to what I wanted, adjusted the products according to my feedback / taste and previous purchasing patterns. Overall I was delighted with the results and grateful for her help. Without her I would probably still be decorating!
