Full Service Interior Design


At Nile Johnson Interior Design, we create spaces that feel like you—elevated, intentional, and effortlessly refined. Based in Kennett Square, PA, we serve discerning clients throughout Wilmington, Delaware, Philadelphia, the Main Line, and beyond, delivering full-service luxury interior design that blends timeless style with tailored functionality.

While our specialty lies in residential interior design, our portfolio extends into boutique commercial work, including a modern office redesign in Washington, D.C., a serene yoga studio in Philadelphia, a curated retail concept, and corporate offices for a regional healthcare agency in Fairmount Park.

Whether you're building from the ground up, gut-renovating a historic gem, or reimagining a single space, we bring clarity and calm to the process through our signature 15-step project management framework. This trusted roadmap guides every project—from initial vision to final install—ensuring a seamless experience, transparent communication, and results that exceed expectations.

Our services include:

  • New construction consulting and architectural planning

  • Full kitchen and bath design

  • Custom millwork and built-ins

  • Construction coordination and finish specification

  • Furniture, art, and accessories sourcing

We’ve also cultivated a global network of experienced trades,  trusted artisans and trade-only vendors, giving our clients insider access to bespoke furnishings, luxury finishes, and one-of-a-kind design elements that bring a project to life.

If you're ready to invest in a home—or space—that feels as good as it looks, Nile Johnson Interior Design is here to lead the way with intention, expertise, and style.
