Elevating homes in Maryland, Washington DC, and beyond with sophisticated interior design 

Establishing your long-term home is such an exciting process. Whether it’s a new build or a historic property, invest in quality design and craftsmanship to curate a home that evolves with you over the years. Interior design is the thoughtful difference between a house and a home that’s uniquely your own.

KATE DUNCAN

East Coast
Principal Designer

Kate helps narrow down options for her clients, and present possibilities they may not have thought of themselves. Some homeowners want to be super involved, so they work closely together with Kate throughout the process. Others prefer to simply move in when everything is placed, cleaned and steamed. Either way, Kate make it a fun and stress-free experience. 

Pillar Interiors helps homeowners make every space inviting and breathtaking all at once. 

Kate is an interior designer in the Washington DC area. She has a passion for weaving together all the elements of a  family-friendly environment, while adding a touch of sophistication and style.

My traditional, eclectic designs prioritize functionality and aesthetics.

“She was a breath of fresh air.”

“Kate has such a wonderful way of finding the in-between; creating a space that fits your vision but will “never go out of style.” We are the trendiest of people but we don’t ever want to feel outdated. Kate listened to that, saw what we loved, and curated a living room and den area beyond expectation. We look forward to working with her again as our house continues to expand.”
