Working with Luminosus Designs
We work with homeowners in Greenwich and throughout Fairfield County seeking full-service interior design, whole-home planning, and kitchen and bath design for renovation and new construction projects.
Each project begins with a close assessment of how the home is used and where thoughtful changes would improve daily life. From there, we develop detailed design plans that may include rethinking layouts, planning whole-home furnishing schemes, and coordinating kitchen and bathroom renovations. We address circulation, storage, lighting, cabinetry, and material selection — creating a comprehensive framework that guides both design decisions and construction.
Our work follows a structured, collaborative process. We develop a clear design plan before construction begins and coordinate closely with architects, builders, and trades from concept through installation. This approach helps manage complex projects while ensuring the final result feels cohesive and well resolved.
For homeowners in Greenwich undertaking renovations or new construction, we are often involved early so interiors can be planned as part of the architecture rather than a separate undertaking afterward — an approach that is especially valuable in architect-designed homes and large-scale renovations.
Why Greenwich
Greenwich’s residential character is shaped by its expansive landscape and a long tradition of well-built homes set on generous properties. The town includes a wide range of architectural styles, from historic colonials and shingle-style houses to more contemporary residences, often surrounded by mature landscaping and designed to take advantage of natural light and privacy. Many of these homes have strong proportions and enduring materials, which is part of what makes them especially rewarding to work with from an interior design and renovation perspective.
Designing in Greenwich is often about building thoughtfully on that foundation—refining layouts, improving how rooms connect, and introducing materials and furnishings that complement the character of the house while supporting contemporary living. Whether a project involves updating a long-established property, planning a kitchen or bathroom renovation, or developing interiors for new construction, the goal remains the same: to create interiors that feel cohesive, natural, and well suited to the people who live there.
Many Greenwich homes sit on larger properties and often support households with varied routines and needs for privacy. In these situations, careful planning becomes especially important. We focus on circulation, natural light, and the relationship between rooms so the home functions comfortably day to day while still feeling calm, balanced, and connected.
If you are planning a renovation or new construction project in Greenwich or elsewhere in Fairfield County, we would be happy to discuss your project.
Each service involves a different level of scope and coordination, but all are approached with the same emphasis on thoughtful planning, clear communication, and careful follow-through.

Kind Words
“From the moment we did the walk through consultation, Mimi spent time listening, observing and connecting what was important to the renovation/update of our home. She really got a feel for what we wanted, and we couldn’t be more pleased with the results. What makes Mimi stand out is not only her knowledge of interior design but her electrical and architectural expertise. The colors, fabrics, furniture and decorative accents that Mimi joined with our sentimental items have made our home such a special place to gather for our family and friends. Every single day I walk through my home and absolutely love what Mimi helped us create. She is simply the best.”
“We were fortunate enough to have Luminosus Designs LLC feature us in an outdoor project.
The design included a kitchen, an optionally covered dining table, and a lounging area in front of a magnificent fireplace. Tying all the details together in a way that allows for natural flow from one area to the next is no easy task. The end result is absolutely stunning! Such a warm and welcoming backyard.
We played a small part in the overall project but are very grateful to be included. Hope to collaborate again!”
