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.”
KAREN VANGSNESS ALLEN | Founder + Principal, Design Studio B

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.
