Grace MacDiarmid, Founder & Designer

My Story

My passion for interior design began when I moved out on my own in my 20s, but it truly blossomed when my husband and I built our first home in 2015, a townhouse in Ashburn, VA. Designing from the ground up ignited my creativity. It wasn’t until we built our forever home in 2018, nestled in the heart of Western Loudoun, that my signature style emerged. Surrounded by the charm of a small, tight-knit community, I embraced a design philosophy that blends timeless tradition with modern touches, creating spaces that feel both current and enduring.

After a successful career in healthcare and project management, I decided to pursue my true passion—helping others experience the true feeling of home through interior design. My background in project management allows me to approach design with a practical, organized mindset, making me a natural at overseeing home builds and renovations from the ground up.

Having built two homes from scratch, I understand the intricacies of bringing a vision to life, from construction to selecting the perfect furnishings. My hands-on experience and eye for detail enable me to create spaces that are as functional as they are beautiful.
