The founder
Design House Interiors is a Sioux Falls-based interior design studio & trade showroom creating warm, timeless interiors for discerning homeowners throughout the midwest and further. Led by principal designer Megan Peterson, we focus on client centered design to deliver spaces that feel like you, only better – homes where every room tells your story with sophistication, comfort, and effortless beauty.
Intentional Design, Inspired by Your Story
About The Studio
With 19 years in the design industry—including 15 as a business owner—Megan has built a career rooted in creativity and meaningful connection.
A graduate with honors from the University of Nebraska’s College of Architecture, she launched her business right out of school while starting a family with her husband, Daryl.
A proud mom of two teenagers, Megan has balanced entrepreneurship and motherhood while even serving as general contractor on both of her family’s homes—shaping her belief that home is deeply personal.
Today, she brings clients’ visions to life through thoughtful, functional design, curates the showroom with standout pieces, and stays inspired through travel, events, and a well-earned cocktail.

Design Philosophy
“We absolutely love our beautiful home and it's largely due to your input on the layout and design. We always appreciate your ideas and patience with us during the building process."
“The Design House is an amazing studio. Would recommend it for any project. They were a big help!"
“This team of designers makes placement of furniture, color selections, and overall design process look easy. They have a beautiful showroom with samples, the best customer service, and the most genuine staff who really care. This should be the first place on your list of businesses to call for interior design or consultation."
