PORTSMOUTH

Katie Rainey – Lead Interior Designer

Serving Portsmouth and the greater Seacoast area of New Hampshire, Katie Rainey Design specializes in full-service interior design for clients seeking refined, deeply personal homes—especially those along the coast and tidal rivers. Our expertise lies in designing spaces that feel like a true escape: homes that are not only beautiful but completely aligned with how you live, entertain, and recharge near the water.

We understand the demands and nuances of designing for waterfront living because it’s our specialty. From balancing natural light and salt air with luxury materials to orienting layouts around the views, we design with intention—ensuring every space feels connected to its surroundings and entirely unique to you.

When guests walk into a home we’ve designed, they often can’t explain exactly what makes it feel different—only that it’s unlike anything they’ve experienced before. That’s the magic of good design. And it’s what we do best.
