For over 20 years, we’ve been designing homes that enhance lives.

As a dynamic team of interior designers and remodeling contractors, we go beyond aesthetics to create homes that foster connection, harmony, and true belonging. 

Our mission is to simplify the complex process of remodeling your home—to make the intimidating accessible—and to ensure you never feel overwhelmed.

We’re not just your designer and contractor; we’re your advocate, your advisor, your expert. Our clients know that their home isn’t just where they live, but how they live.

“Interior design is not just about aesthetics; it's about creating spaces that truly transform lives.”

Let us guide you to discover the true potential of your home, and your life within it.

ABOUT DESIGN STUDIO B

Reimagining your home offers you the chance to do more than just make a few changes, but instead to create a transformation in how you live. 

To create a home that is an extension of your identity, your values, and your aspirations.

A space that isn't cluttered with generic objects but filled with cherished memories and traditions. A home that nurtures and protects your most treasured investments; one created not just for a hypothetical future buyer, but tailored exclusively for you and your family.

We understand the power of transformation—and how spending time in an environment that makes us feel welcome and at ease, can change our life. 

Our designs not only renew your physical space, they refresh your lifestyle within it.  

Your home is more than just an asset.

Let us guide you to discover the true potential of your home, and your life within it.

What our clients say about working with us

  • "The project manager was so outstanding and their attention to detail and making sure everything is just right was unbelievable. Their whole Mission is to have this be something that is minimally disruptive to you as possible and they succeed in that mission. This was a wonderful experience from start to finish."

    Maggie and Jim | Rochester, MN

  • "Karen and her Design B Team are fabulous. With their professional expertise and design skill, we have gorgeously transformed 4 bathrooms, 3 bedrooms and two living spaces. Our style preferences were truly embraced, but more importantly Karen provided gentle guidance when we struggled to make a design choice. Our home is now a cohesive and vibrantly comfortable place."

    Sarah and Robert | Rochester, MN

  • "We have finished two major home remodels with Karen at Studio Design B. One spanned the pandemic and we were impressed with the professionalism that was shown assuring the necessary precautions were taken. At the end, we loved our master bathroom remodel. Every detail worked out as expected creating a clutter free, soothing space. Our second project involved a remodel of our remaining bathrooms and kitchen. We greatly appreciated Karen's expertise in navigating some of the limitations our spaces presented to again create sophisticated areas you love to walk into. We love our kitchen and Karen’s creative solutions to storage. I cannot say enough good things of Staci and the rest of the team. The communications were always on point, easy to reach and ready to address any concerns. We highly recommend!"
