ABOUT

Lionel William Consulting and Design is a high-end, bespoke interior design firm redefining the way people experience space. Founded in 2017 and originally based in Los Angeles, the company now calls South Florida home while continuing to work with discerning clients across the country—from Miami and New York to Los Angeles and destination enclaves like Incline Village.

We believe design is more than aesthetics—it’s about creating environments that shape how people feel, think, and connect. Our work blends luxury with livability, crafting interiors that are as functional as they are beautiful. We design spaces that enhance well-being, improve focus, and elevate everyday living, ensuring each environment resonates deeply with its inhabitants.

Our Philosophy

Lionel William Consulting and Design stands apart as both exclusive and approachable. We value discretion, creativity, and innovation, but we never lose sight of the people at the heart of our projects. Each design is not just about space—it’s about experience, designed to foster connection, comfort, and beauty.

Whether curating a serene beachfront retreat, staging a metropolitan penthouse, or consulting on a large-scale development, our guiding principle remains the same: to design spaces that move people.

INTERIOR DESIGN

At Lionel William Consulting and Design, interior design is the heart of our practice. We create bespoke environments that are as livable as they are luxurious, tailoring every project to reflect the individuality of our clients while upholding the timeless elegance that defines our brand.

Our interiors are crafted through a dialogue between artistry and functionality. From architectural finishes to curated furnishings, lighting, and textiles, every element is chosen with intention. Guided by principles of neuroaesthetic psychology, we design with an understanding of how spaces influence human emotion, behavior, and well-being. A well-placed window, a balanced color palette, or the scale of a room can transform not only how a space looks, but how it feels.

We specialize in both residential and commercial projects, ranging from serene beachfront retreats and sophisticated urban penthouses to brand-driven office environments and hospitality spaces. Whether intimate or expansive, our interiors are always designed to inspire connection, comfort, and enduring beauty.

DESIGN CONSULTATION

Our consultation services extend our expertise into the building and development process, offering value from the ground up. We collaborate with builders, architects, and developers to enhance the design integrity of projects, ensuring they succeed aesthetically, functionally, and commercially.

Our consultations focus on layout optimization, lighting design, material selection, and spatial flow—the elements that transform a property from ordinary to extraordinary. By integrating design intelligence early in the process, we help avoid costly revisions while elevating the long-term market appeal of the development.

This sector is also where our neuroaesthetic approach is most impactful. We bring insight into how design decisions affect buyer perception, livability, and emotional connection. A development guided by Lionel William is not just visually appealing—it resonates deeply with those who live within it, ensuring stronger desirability and greater return on investment.

Whether advising on a single luxury residence or a large-scale multi-unit development, our consultation ensures that every project reflects both timeless design principles and modern livability.

LUxuRY STAGING

In today’s competitive market, presentation is everything. Our luxury staging services transform properties into aspirational showcases that highlight their full potential. Unlike conventional staging, our approach is grounded in design psychology—understanding how space influences perception, mood, and decision-making.

We design each staging project to evoke a lifestyle, not just a look. From curated furnishings and art to strategic spatial flow, our staging highlights architectural strengths, enhances natural light, and creates an emotional connection that inspires buyers to imagine themselves at home.

Our work has been proven to help properties sell faster and at higher values, making staging not only an aesthetic service but a strategic investment. Every staging project is tailored to the home’s character and target audience, ensuring a result that feels seamless, sophisticated, and unforgettable.
