About —

Led by Marcelline Jastrab, Studio Celline creates residential interiors that are timeless, layered, and quietly refined.

Her work blends natural materials, soft tones, and tactile textures to shape spaces that feel warm, inviting, and thoughtfully composed. Light and shadow are treated as essential elements in every room, creating environments that allow for breathing, both visually and in daily life. Each project becomes a considered reflection of the client’s vision, rooted in care, clarity, and ease.

Marcelline’s career has taken her from San Francisco to Seattle and New York City, offering broad exposure to diverse styles and project scales. She collaborates closely with clients, architects, and builders, fostering a process that is thoughtful, transparent, and seamless from concept through completion.

Studio Celline integrates bespoke elements, timeless pieces, and the work of emerging artists and makers to create highly personalized interiors defined by comfort, calm, and refined simplicity. Textures are layered, surfaces are luminous, and each piece is selected to support both form and function.

Marcelline is currently based in Connecticut with her husband and their two British Shorthairs.

Services —

Studio Celline offers a range of services that can be tailored to each unique project and, when needed, integrated seamlessly with an architectural team.

  • Each engagement begins with a tailored workshop to gain a clear understanding of your goals, style, and project brief.

  • From there, support can take the form of smaller interventions, such as furniture procurement and property styling, or more comprehensive deliverables, including FF&E schedules detailing materials, lighting, and furnishings.

  • Most impactful is the full-scope interior design service, which builds a complete creative solution from initial concept design, through detailed documentation, to project management and oversight during construction.
