Greenwich Architects for Custom Homes & Thoughtful Renovations

Tanner White Architects is an award-winning residential firm serving Greenwich and the surrounding Fairfield County communities from our studio in nearby Westport, CT. Since 2012, we’ve designed custom homes, additions, and full renovations that balance beauty, function, and sustainability — and that reflect how each family actually wants to live.

Whether you’re building a new residence, restoring a historic property, or reimagining a home you already love, we bring a thoughtful, client-centered approach to every project in Greenwich.

Our Work Across Greenwich

Greenwich is a patchwork of distinct settings, and good design starts by responding to each one. Our residential projects span the town’s neighborhoods — from waterfront properties in Belle Haven to country estates in backcountry Greenwich and transitional homes closer to the downtown core.

Every design honors its setting while delivering modern comfort, careful detail, and a sense of permanence. You can see how that plays out in projects like our Belle Haven residence and our bespoke Greenwich home, or browse our full portfolio of residential projects.

Custom New Homes

We design ground-up residences tailored to your site, your lifestyle, and the character of the neighborhood — from classic New England shingle-style to clean contemporary. The process starts with listening: understanding how you live before we ever put pen to paper.

Renovations & Restorations

Greenwich is rich with architectural history, and many homeowners come to us to adapt an existing home to changing needs — a growing family, more open living space, or a fuller integration of modern systems. Our renovation work includes:

Historic restoration — preserving architectural character while modernizing for comfort.
Additions & expansions — blending new construction seamlessly with the existing home.
Interior reconfiguration — opening up floor plans to suit how families live today.
Exterior enhancements — refining facades, porches, and outdoor living spaces.

Integrated Interior Design

Architecture and interiors are inseparable when you’re building a home of lasting quality. We collaborate closely with Greenwich-area interior designers so the experience flows from exterior to interior — space planning, millwork, lighting, and finishes all working toward one coherent vision.

Sustainable, Energy-Efficient Design

Eco-friendly building is a through-line in our work. Founder Tanner White brings green-building principles into every project, with design strategies that include:

Energy-efficient building envelopes
Geothermal and solar integration
High-performance windows and insulation
Water-saving landscape design
Reclaimed and locally sourced materials

Frequently Asked Questions

Are you based in Greenwich?

Our studio is in Westport, CT, a short drive from Greenwich, and Greenwich is one of our primary service areas. We work throughout the town and the wider Fairfield County region.

Do I need an architect for a home renovation in Greenwich?

For anything beyond cosmetic updates — additions, structural changes, or reconfiguring floor plans — an architect helps you get the design, permitting, and construction details right the first time. Many Greenwich renovations also involve historic or neighborhood considerations that benefit from experienced design guidance.

What architectural styles do you design?

We work across a wide range — from classic New England farmhouses and shingle-style homes to clean contemporary and coastal designs — always shaped by the site and the client rather than a single signature look.

What areas do you serve besides Greenwich?

Alongside Greenwich, we design homes in Darien, New Canaan, Westport, and Fairfield, plus Westchester County, NY.
