Windhill Builders, LLC

What Windhill Builders, LLC does

Windhill Builders, LLC, doing business as Windhill + Co., is a privately held Massachusetts custom home builder and design-build firm founded in 2003 by Shawn Cayer and headquartered in Ipswich, Massachusetts. The company operates four integrated service branches: Custom Home Building (new homes, additions, and whole-house renovations), an in-house Woodworking & Cabinetry shop in Georgetown, MA, Whole Home Services (small projects and seasonal maintenance), and Windhill Realty (a boutique North Shore real estate agency). Its primary customer segment is high-net-worth homeowners in the greater Boston region, the North Shore, coastal Maine, and New Hampshire, with secondary demand from regional architects and interior designers seeking custom millwork.

The business model is project-based and quote-driven for construction, woodworking, and renovation work, with multi-year contract cadences; realty services generate transaction fees, and Whole Home Services operates on professional-services billing. Windhill leverages three generations of family home-building experience and a senior leadership team that includes Stephen Szabo (40 years of fine custom woodworking, published in Architectural Digest and Better Homes & Gardens) and Chris Sabelli (Director of Construction Operations, experienced in multi-million-dollar luxury custom home projects). The go-to-market motion is direct-to-consumer, augmented by referrals from regional architects and design partners, with marketing channels including a Fieldnotes blog, newsletter, social media, and SEO.

The firm is founder-owned, privately held, and operates without disclosed external investment. In 2024 it underwent a brand evolution to Windhill + Co. to formalize its holistic four-branch positioning, signaling a strategic intent to deepen client lifetime value via recurring maintenance and realty services alongside the core construction business. No proprietary technology platform, AI capabilities, or disclosed headcount, revenue, or funding data are present in available sources.
