About Studio 427

Owners Laura Austin-Bullock and Dawnn Marvin have over 40 years of experience in interior design.  They decided to join forces and open Studio 427 in October 2007.  Studio 427 focuses on interior design and décor for both residential and commercial appointments.

The Studio 427 showroom is a showcase for unique accessories, custom furniture, fabrics and window treatments for the home or business.

Studio 427’s design and consultation services help their clients overcome their decorating challenges and dilemmas.  Laura and Dawnn are assisted by Lora Holton and Nancy Sissel.  Lora previously owned her own home décor boutique and Nancy specializes in kitchen layout and design.

Laura and Dawnn invite you to let the Studio 427 team design for you.
