Where Timeless Elegance Meets Modern Living.

JG O’Neil Designs is a Connecticut based interior design firm dedicated to creating sophisticated living spaces with a soul. Our design philosophy is rooted in the belief that the most compelling spaces are those that tell a story. By expertly mixing vintage and antique with modern pieces, we create interiors that feel curated over time rather than styled for a moment. Whether selecting a contemporary statement piece or sourcing a one-of-a-kind antique, our goal is to find the perfect tension between old and new—resulting in homes that are sophisticated, layered, and deeply personal.

Our Services:

  • Full-Service Interior Design: From initial concept to final installation, we guide you through every step of the design process, including space planning, furniture selection, custom cabinetry, lighting design, window treatments, and art curation.

  • Antique & Vintage Sourcing: Our experienced team specializes in sourcing exquisite antique and vintage pieces, including furniture, decorative objects, and art, to add character and depth to your interiors.

  • Modern & Contemporary Integration: We seamlessly integrate modern and contemporary elements, such as sleek furnishings, innovative lighting, and cutting-edge technology, to create a balanced and harmonious aesthetic.

  • Art Curation & Installation: We work with art galleries and artists to curate and install art collections that enhance the visual impact and personality of your space.

  • Project Management: We oversee all aspects of the design and construction process, ensuring that your project is completed on time and within budget.
