Tower Design is an award-winning, full-service interior design studio based in the San Francisco Bay Area and established in 1996. Our work is defined by a deeply considered, holistic approach—where architecture, interiors, and lifestyle converge to create environments that are both refined and enduring. We specialize in crafting highly personalized residences for discerning clients who value exceptional design, meticulous execution, and a seamless experience. From concept through completion, our process is intentionally streamlined to support busy individuals who expect discretion, precision, and thoughtful stewardship of every detail
We design interiors for Atherton’s most distinguished estates with a focus on scale, proportion, and quiet luxury. Each residence is tailored to reflect the individuality of its owner, with an emphasis on bespoke detailing, curated materials, and architectural cohesion.
Our Los Altos projects balance modern refinement with livability. Clean-lined architecture is softened through layered textures, custom furnishings, and thoughtful spatial planning that supports both everyday life and elegant entertaining.
In Los Altos Hills, our work responds to landscape and light. Expansive homes are shaped into warm, livable environments through intentional flow, elevated material palettes, and a strong indoor–outdoor connection.
We approach Portola Valley with restraint and sensitivity to its natural surroundings. Interiors are quietly sophisticated—rooted in organic materials, nuanced color palettes, and an understated elegance that endures.
Our Ross interiors honor architectural tradition while introducing a more relaxed, livable refinement. The result is a layered, timeless aesthetic that feels both established and current.
For waterfront homes, we design with light, air, and view as primary elements. Interiors are composed to frame the landscape, creating a seamless dialogue between interior spaces and the surrounding bay.
In Saratoga, we create residences that support both intimate daily living and large-scale entertaining. Our designs balance comfort with polish, ensuring every space feels considered yet inviting.
Our coastal work reflects an effortless sophistication. Natural textures, softened palettes, and relaxed forms come together to create homes that feel both elevated and deeply connected to their setting.
