Leah Muller Interiors of Sebastian

Leah Muller Interiors of Sebastian is an interior designer in Sebastian, FL. The firm is known for its signature coastal modern approach, blending new and custom furnishings with cherished existing pieces to create refined, comfortable living spaces. The work is built around relaxed rattan, breezy linens, neutral palettes, and accents of watery blues and citrus tones, with interiors shaped through both styling and interior architectural coordination. Leah Muller launched her career in Florida in 1994, following a four-year stint at two architectural firms and running her own studio in Philadelphia. That early architectural training continues to inform the millwork, ceiling treatments, fabrics, and bedding details found in each custom build and remodel the firm takes on. The clientele stretches across the United States and includes city apartments, country club estates, island cottages, and seaside homes, with many clients returning for additional homes over time.

The Sebastian studio sits on Beachland Boulevard, where the team works both in the studio and on-site with clients to develop each phase of a project, presenting fresh ideas and products on the boards and applying deliberate editing techniques to refine the result. The firm maintains a rating of 4.90 based on the reviews left by its clients.

With three decades of Florida practice behind it and a principal widely regarded as one of the most talented designers in the state, Leah Muller Interiors brings a rare architectural grounding to coastal modern interiors along Florida's Treasure Coast.
