What We Do

From breaking ground on a legacy home to preserving one that's stood for a century, Fifth & Dune brings the same level of craft, care, and commitment to every project. We build, restore, renovate, and protect homes across the East End, from Westhampton Beach to Montauk.

Custom homes

Ground-up construction built to your vision.

Every custom home begins with a blank canvas. We work closely with your architectural team from the earliest stages — navigating coastal setbacks, local building codes, and site-specific challenges — so that what's drawn on paper becomes exactly what's built on your land. No surprises, no shortcuts.

Major renovations

Elevating what's already there.

Renovation work requires a different kind of thinking. Once the walls come down, the real story begins. We bring critical thinking, honest communication, and bespoke craftsmanship to whole-home remodels and significant additions — honoring the character of your home while elevating it to something extraordinary. 

historic preservation

Honoring what came before. Building for what's ahead.

Preserving a historic home means balancing reverence with pragmatism. Original details must be protected. Modern systems must be integrated. Regulatory approvals must be navigated. Fifth & Dune takes this work on with pride — we operate out of a restored c.1895 building ourselves, and we understand what it means to bring history forward.
