Before stepping into firm leadership, she built a diverse career shaped by both design and business experience. After managing a multi-line showroom at Chicago’s Merchandise Mart, she joined Scott Arthur Yerkey Design, where she earned First Place at the IL ASID Design Excellence Awards for her work on the Lake Forest Showcase House in 2013.

Her dedication to community-based design has also been recognized through her volunteer work with Designs for Dignity, where she received the organization’s Founder’s Award in 2014 for a collaborative project with Chicago House.

Lindsay holds a Bachelor of Fine Arts in Interior Design from the Harrington College of Design. She continues to draw inspiration from travel, architecture, art, and the ever-evolving intersections of culture and design—believing that the best spaces tell the stories of the people who live and work within them.

What is your favorite part of being in design?

My favorite part of design is the collaboration with artists and craftspeople that we work with to develop our custom interiors. The final pieces are always a work of art.

What’s your personal design style?

My design style is a collected look with a mixture of contemporary pieces and traditional design elements that blend into a new style. This style has the feel of being traveled and collected over the course of a lifetime, rather than purchased all at once.

What would be your dream project?

A dream project would be the redesign of the White House’s private quarters for a future administration.

Born and raised in Baltimore, MD, Peyton received her Bachelor of Fine Arts Degree in Interior Design and a minor in French from Miami University (OH). While at Miami, Peyton was on the executive board of Miami’s collegiate chapter of IIDA, and spent a semester abroad at Miami’s campus in Luxembourg. She spent multiple summers interning at the esteemed design firm RD Jones in Baltimore, before moving to Chicago to begin her career with us. She joined the firm in January 2025, and she is thrilled to be a part of the design team at KSA.

What’s your personal design style?

I would consider my design style as eclectic. A blend of textures, muted tones, antique pieces, and contemporary elements that make a space feel layered and refined. I believe by including pieces and art from places I have traveled tells a story and ties a space together.

What elements define your style? Where do you find inspiration?

I find inspiration through traveling. I have always had a passion for learning about and experiencing other cultures. Combining my lived experiences with historical context fuels my creativity when designing spaces.

What would be your dream project?

My dream project would be designing a cliff side home in Big Sur, California. The contrast between the lush greenery and jagged cliff edges that disappear into the Pacific would create a unique design concept that I would love to see realized.
