Meet Siena & Birch

Siena & Birch Interior Design is a boutique design studio creating soulful, lived-in interiors that blend vintage charm with modern ease. We help busy, design-conscious women transform their homes into beautiful, grounded spaces—with European-inspired character, intentional layering, and unpretentious luxury.

With a background in global brand creative and a heart for interiors, we bring both storytelling and structure to the design process. Our approach is rooted in slowing down, tuning in, and designing for a life well lived—at your pace, in your style, and with room to breathe.

Hi,

I’m Kelly Littleton, owner and designer of Siena & Birch Interior Design in New York’s Hudson Valley.

Before interiors, I spent over a decade at Google leading award-winning brand campaigns, and earlier honed my design eye as the right hand to fashion designer Michael Kors. Today, I bring that mix of creativity and rigor to every project—clear processes, open communication, and a simple, step-by-step plan that turns inspiration into rooms you’ll actually live in and love.

If you want a home that’s grounded, personal, and quietly luxurious—without the fuss—you’re in the right place. Let’s make something beautiful together (and have a little fun along the way).
