Interior Design & Architecture for How You Live

Luxury, Simplified.
Full-service interior design for Westchester County, Fairfield County, and New York City.

A truly luxurious home should not ask to be managed. It should welcome you in, carry you through the day, and quietly support the way you live. It should function beautifully, feel generous, and unfold with ease. At Luminosus Designs, we create homes that feel composed without feeling staged—places where light, proportion, and texture come together in a way that feels natural and unforced. Led by Mimi Fong, the studio guides each project from first sketch to final installation, so what might feel complex becomes calm, clear, and deeply satisfying.

DESIGNING FOR HOW YOU LIVE

GEvery home has its own rhythm. Mornings, evenings, weekends, quiet moments, and full tables all ask different things of a space. Great design begins there—every decision, from layout and materials to proportion and light, should support daily life while feeling thoughtful and well considered.

At Luminosus Designs, we start by understanding how your home is actually used—how you move through it, where life naturally gathers, and where it should feel more calm, more open, or more contained. These patterns shape the layout, guide the flow, and inform every material and finish that follows.

The result is a home that feels intuitive to live in. Rooms feel connected without feeling busy, spaces feel generous without feeling formal, and the house begins to work in a way that supports daily life instead of competing with it.

WHAT SETS US APART

Visionary Design. Impeccable Execution.

Great concepts are only as strong as their execution. With more than two decades of experience, Mimi brings vision and delivery into a single, continuous process. Each project is guided with clarity and close attention to detail, so what is imagined is also what is realized—faithfully, coherently, and with great care.

Tailored Interiors with a Curated Edge

Each home is approached as a one-of-a-kind project. Furnishings, finishes, and details are selected—or custom-developed—to suit our clients’ visions and the rhythms of their everyday life, resulting in interiors that feel cohesive, personal, and quietly distinctive.

Design as a white-Glove Experience

Service at Luminosus Designs is as personalized as the design itself. Every phase is managed with discretion and clarity, allowing the process to feel streamlined, supportive, and genuinely enjoyable from start to finish.

Meet Mimi Fong

Mimi Fong approaches each project with a rare combination of creative vision and clear, steady judgment, shaped by more than two decades of experience. Her work is grounded in a deep understanding of how people live—and in the belief that a home should feel as good as it looks.

An NCIDQ-certified designer and a member of the American Society of Interior Designers and the National Kitchen & Bath Association, Mimi has worked on projects ranging from single-room renovations to furnishing entire homes, from New York and Connecticut to the Caribbean and China.
