Margaret Donaldson opened the doors of MDI in 1988. With an interior design degree from the University of Georgia, she stepped out to create what would prove to be one of Charleston’s most respected interior design firms.

A Charleston native, Margaret absorbed the Holy City’s underlying style and class. That, coupled with her discerning eye and education, makes Margaret a remarkable designer. Always beginning with a discovery of the client’s desire, her projects pair the elements of design with an emphasis on function, thereby creating spaces that are not only beautiful, but livable. Known for layering colors and textures, her work conveys a sense of balance and distinctiveness. There’s a subtle elegance and order to the design. The design does not feel over decorated or contrived but as though it is the consequence of an inspired vision.

Margaret’s work ranges from a 19th century plantation to resort condominiums and from an upscale retirement community to a lively orthodontist's office. An advocate for preservation, her work on the renovation of an historic kitchen house received national recognition on HGTV’s “Interiors by Design.” As the interior designer for Southern Living’s Idea House on Daniel Island, Margaret again gained national attention and reaffirmed MDI’s position as a leading design firm.
