In Atherton, luxury is rarely loud. It is expressed through architectural purity, exceptional materials, museum-quality craftsmanship, and homes that feel deeply personal, curated, and impossible to replicate. At Tower Design, we create highly customized modern residences for discerning clients seeking interiors that feel artful, refined, and architecturally significant. Our work is designed for collectors, visionaries, and homeowners who value contemporary design at the highest level — homes where architecture, furnishings, art, and atmosphere exist in complete harmony.
The most exceptional contemporary homes feel effortless — yet every element has been carefully considered.
Our interiors are defined by sculptural forms, refined palettes, layered natural materials, bespoke furnishings, and carefully integrated art collections that create visual impact without excess. We design homes that feel calm and restrained while carrying a strong architectural and artistic presence.
Tower Design works with clients seeking:
Rather than following fleeting trends, we create residences that feel culturally informed, quietly luxurious, and enduring over time.
Exceptional homes require far more than aesthetic direction alone. They require precision, discretion, organization, and an uncompromising level of detail.
Tower Design provides a comprehensive full-service interior design experience overseeing every aspect of the project from architectural collaboration through final installation and styling. We work closely with architects, builders, fabricators, galleries, artisans, and specialized trades to ensure the integrity of the design vision is maintained at every phase.
Our services include:
Many of our clients lead highly demanding professional lives and value a design experience that feels seamless, organized, and discreet. Our role is to thoughtfully manage every layer of the process while delivering interiors of exceptional quality and originality.
The result is a residence that feels cohesive, elevated, and entirely bespoke.
Our clients are often deeply connected to contemporary architecture, fine art, travel, and design culture. Many are collectors of art, furnishings, or custom pieces and seek homes that feel sophisticated without becoming overly formal or performative. We believe true luxury is found in atmosphere, proportion, craftsmanship, and emotional resonance. Every project begins by understanding how our clients want to experience the home: How they entertain. How they live privately. How they collect art. How they want the space to feel emotionally and visually. Those insights become the foundation for interiors that feel immersive, highly personal, and architecturally integrated. From expansive entertaining spaces and private wellness retreats to dramatic gallery-like corridors, sculptural staircases, executive offices, and resort-inspired outdoor living environments, every detail is designed with clarity, balance, and intentionality. Rather than relying on excess, our work focuses on creating homes that feel collected, timeless, and visually unforgettable.
