Design Approach

KJID is a multi-faceted boutique firm specializing in both residential and commercial projects. Katharine personally oversees the planning of each project from the start of construction through the finished product. Katharine and her team establish and maintain direct client relationships throughout the entire project, listening to the needs and vision of the clients. The result is a unique design that reflects each client’s individuality and taste. Katharine's attention to detail, ability to mix finishes and materials, has led to the creation of elegant spaces that are functional and stylish.
