Timeless Interiors. Global Sensibility. Absolute Discretion.
At Tower Design, we specialize in creating refined, deeply personal residential interiors for a discerning clientele—those who live in Beverly Hills as their sanctuary. Many of our clients are luminaries in film, media, and global business—individuals who value beauty, privacy, and cultural nuance. They aren’t drawn to flash or fanfare. They seek sophistication with soul. We design homes that mirror that lifestyle: elegant, tailored, and quietly luxurious.
Beverly Hills isn’t about sameness—it’s about distinction.
We don’t impose a style. We uncover and elevate yours.
Each project begins with deep listening. We consider the architectural language of your home, your personal rituals, your travels, your art—and design accordingly. Our work is understated yet masterful, blending restraint with richness and functionality with emotion.
We specialize in interiors that speak to:
While every home is a custom creation, our work in Beverly Hills often integrates the following modes of design:
Tactile neutrals, sculptural forms, and layered materials sourced from around the world—emphasizing serenity over show.
A nod to cinematic glamour—without cliché. Think hand-blown glass, heritage silk drapery, and bespoke light fixtures in dialogue with clean-lined furniture.
Natural light, artisan ceramics, handwoven rugs, curated books and quiet luxury. Understated interiors that are designed for real life.
With Beverly Hills’ exceptional climate, we design spaces that dissolve boundaries—framing views, expanding patios, and creating courtyards that echo the interior ethos.
Tower Design Interiors is a client-focused, full-service interior design firm with expertise in luxury residential and commercial interior renovation and decoration.
From architectural detailing to final placement of objects, we work seamlessly with architects, builders, and artisans to ensure your vision is realized with precision and grace.
We reimagine legacy homes while honoring their soul—updating layouts, finishes, and systems for today’s living without erasing the integrity of what came before.
We solve the unsolvable—creating harmony in floor plans, expanding light, and ensuring that every room supports both daily life and elevated entertaining.
From rare wood species to honed stone and custom hardware, we hand-select every finish to ensure timelessness, tactile beauty, and elevated durability.
We curate—not decorate. Our team sources internationally, layering contemporary design with antique or ethnographic finds, custom pieces, and museum-quality art.
This is the finishing touch—the layer that transforms a space into a sanctuary. Lighting, textiles, florals, sculpture. Every element is calibrated for mood, movement, and emotional resonance.
I highly recommend Tower Design Interiors. Their ability to source just the right furniture, art, decor, architectural element, etc. is always with a sophisticated understanding of color, architecture, design and art that surpasses anyone else we have worked with. We are thrilled with our current project. Excellent skillful service. Great communication, highly professional, organized. We recommend Tower Design Interiors.
