The Hamptons’ Best-Kept Secret Boutique
Before Natasha Esch was curating timeless treasures from the 18th century to modern day, she was President of Wilhelmina Models and an Interior Designer in Los Angeles. That background—understanding both human beauty and spatial design—infuses every corner of Monc XIII, the furniture and home accessories destination she founded with husband Matt Coffin in downtown Sag Harbor.
Located at 40 Madison Street, this boutique design shop carries Cassina, Fritz Hansen, and pieces you won’t find elsewhere on the East End. The store feels aesthetically anchored in its old whaling town location while allowing modern materiality to shine through—simple, yet chic, representing both the air of its curator and the extraordinary contents within.
Why Monc XIII Attracts Design Connoisseurs
The buying philosophy distinguishes Monc XIII from typical furniture retailers. Esch travels the globe seeking unique and timeless treasures across centuries. The result: a curated selection impossible to replicate through conventional distribution channels.
The Curatorial Eye
Mid-century modern, vintage, and new furniture coexist in the showroom. Poul Kjærholm PK20 lounge chairs. Le Corbusier pieces from iMaestri collection. Ib Kofod-Larsen Scandinavian designs. Each item earns its place through quality and character rather than trend alignment.
The Design Trade Connection
Interior designers access trade pricing on pieces that furnish the Hamptons’ most sophisticated homes. The showroom functions as resource for professionals and destination for collectors who understand furniture as investment.
What Makes Monc XIII Different
The Sag Harbor location delivers design culture within walking distance of harbor views and village restaurants. This integration of serious design with vacation atmosphere creates experiences unavailable in urban design districts.
The Physical Space
Architect collaboration with Arcologica created a space respecting Sag Harbor’s historic character while enabling contemporary presentation. The store serves multiple purposes—showroom, gallery, and gathering point for design-minded visitors.
Beyond Furniture
Lighting and luxury home accessories complete the offering. French linens, leather-clad coolers, Hermès china. These objects transform houses into homes while signaling the refined taste of their owners.
The Location Advantage
Sag Harbor’s preserved whaling village character creates perfect context for furniture that honors craft traditions. The Madison Street location sits steps from Main Street shopping and harbor waterfront.
The Greenwich Expansion
A second showroom at 5 Lewis Court in Greenwich, CT extends the Monc XIII experience to Connecticut residents. This dual presence serves the metropolitan design community year-round rather than limiting access to summer months.
Shopping the Collection
The showroom operates daily 10 AM to 6 PM. Purchases available directly off the showroom floor eliminate the waiting typical of custom furniture ordering.
Price Positioning
Fritz Hansen PK20 chairs command $15,800. Vintage Scandinavian pieces range into five figures. These prices reflect museum-quality provenance and construction that outlasts fashion cycles.
Online Access
The Incollect platform extends inventory visibility to remote shoppers. Design trade members access pricing unavailable to general public. This hybrid model serves both casual browsers and serious collectors.
Planning Your Visit
Monc XIII rewards visitors who appreciate design history and quality construction. The experience differs fundamentally from furniture shopping—closer to gallery visiting than retail browsing.
What to Expect
Knowledgeable staff provides context for pieces spanning centuries and continents. The atmosphere encourages conversation about design rather than transactional purchasing. Serious collectors find resources unavailable elsewhere on the East End.

The Bottom Line on Monc XIII
Design culture exists in the Hamptons beyond the Parrish Art Museum. Monc XIII represents the applied dimension—furniture and objects you can actually live with rather than observe through glass. For visitors who understand that home furnishing represents personal curation rather than convenience shopping, this boutique delivers experiences worthy of the journey.
