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 are warm, inviting, and thoughtfully designed. Light and shadow are considered elements in every room, creating spaces that allow for breathing, both visually and in daily life. Each project becomes a curated 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, giving her broad exposure to diverse styles and project scales. She works closely with clients, architects, and builders, fostering a process that is thoughtful, transparent and satisfying from concept through completion.

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

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.
