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 deeply 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.

  • Collaboration with clients, architects and builders ensures every design element aligns seamlessly with the client’s vision. Each project is guided through spatial planning, material selections, and interior detailing to create cohesive, intentional spaces that balance function and beauty.

  • Transforming an existing home begins with a thoughtful reimagining of layout, flow, and purpose. Comprehensive design direction brings continuity to materials, finishes, and furnishings, resulting in a renewed space that feels both familiar and entirely refreshed.

  • A single room can redefine the character of a home. Through curated updates to finishes, furnishings, or lighting, each refresh brings focus, harmony, and renewed energy to the space.

  • Carefully considered furniture selections, custom pieces, and layered styling details refine the atmosphere of any interior. Each composition is tailored to express character, comfort, and cohesion within the home.

  • Targeted design guidance provides clarity for any project stage. Consultations may include spatial layout advice, color and material direction, or sourcing recommendations. This service offers clients a clear path forward with confidence.
