Ben Krupinski Builders

What Ben Krupinski Builders does

Ben Krupinski Builders is a privately held luxury general contracting firm founded in 1986 by Ben Krupinski, headquartered in East Hampton, New York, with a second office in Old Greenwich, Connecticut. The firm designs and constructs custom homes, custom renovations, public and institutional buildings, and provides ongoing property maintenance across the Hamptons, New York City, and Connecticut. The company is currently owned and operated by principals Stratton Schellinger and Ray Harden, who succeeded the founder and continue to run the firm as a privately held, principal-led business with no outside capital.

The business model is project-based and relationship-driven: contracts are executed on a bespoke basis with affluent private clients and select institutional customers, typically in collaboration with leading architects such as Adjaye Associates, Annabelle Selldorf, Bates Masi + Architects, Barnes Coy Architects, and Herzog & de Meuron. Notable completed works include the Parrish Art Museum (Herzog & de Meuron), the East Hampton Library, and Guild Hall, which demonstrate the firm's capacity to execute architecturally ambitious projects at the premium end of the market. Revenue is generated through fixed-price and cost-plus construction contracts on individual projects, supplemented by recurring post-completion maintenance agreements, with no disclosed recurring software, subscription, or platform revenue.

The underlying technology is traditional construction craft and project management rather than a software platform, proprietary product, or patented process. Competitive differentiation rests on brand reputation, principal-level client service, and an established regional network of specialty subcontractors and craftspeople in the Hamptons/NYC/CT corridor. There are no disclosed AI/ML, data, or digital platform components in the offering.

Direct peers

• Filo Construction: Long Island / Hamptons luxury residential general contractor delivering custom estates and high-end renovations. Operates in the same HNW East End market, with comparable project scale, custom craftsmanship focus, and reliance on architect referrals — a direct substitute for Ben Krupinski on luxury Hamptons RFPs.
• Kiener Homes: Hamptons-based custom home builder focused on luxury new construction and renovations for high-net-worth clients in East Hampton, Southampton, and Bridgehampton. Directly comparable in product offering, geography, and the relationship-driven, architect-partnered delivery model.
• Bluewater Builders: Hamptons and Long Island luxury residential builder specializing in custom beachfront estates and high-end renovations. Directly comparable in geography, beach/coastal luxury focus, and custom craftsmanship for HNW owners.
• Mark P. Finlay Architects (Builder GC arm): Southampton-based design-build firm offering integrated architecture and construction for luxury Hamptons estates. Comparable on integrated design-build delivery, HNW Hamptons clientele, and custom-estate project scale.
• Beechwood Homes: Long Island / Westchester custom home builder serving affluent suburban and estate clients. Comparable on HNW residential custom-home delivery and craftsmanship focus, though with somewhat broader geography including Westchester that overlaps with BK Builder's Connecticut extension.
• Bulgin Construction Group: Long Island–based luxury custom home builder and general contractor specializing in high-end residences in the Hamptons and North Fork. Most directly comparable to Ben Krupinski Builder in geography, customer segment (HNW residential), and project scale, and competes for the same architect-driven project pipeline.
• John S. Johnson Construction: Long Island luxury residential construction firm with a strong Hamptons and North Shore portfolio. Comparable in custom-home and renovation focus, HNW client base, and architect partnership model, making it a directly competing regional luxury GC.

Others

• Robert A.M. Stern Architects: New York-based architecture firm and longstanding partner of Ben Krupinski Builder on the East Hampton Library and other traditional luxury residences. Not a direct competitor, but a critical source of architect referrals for traditional-style luxury projects in the Hamptons and NYC markets.
• Bates Masi + Architects: Hamptons-based architecture firm whose Three Mile Harbor project with Ben Krupinski Builder won Builder Magazine's 2024 Project of the Year. Not a builder peer, but a key architectural referral partner — Bates Masi's design language and Hamptons focus generate a steady stream of compatible projects for BK Builder.

Broad incumbents

• Toll Brothers: National luxury homebuilder with significant presence across the Northeast including New York, New Jersey, and Connecticut. While operating at much larger scale and primarily in for-sale luxury communities rather than one-off custom estates, it competes for the same affluent luxury-buyer segment and represents the scaled incumbent alternative to bespoke builders like Ben Krupinski.
