Windhill + Co.

What Windhill + Co. does

Windhill + Co. is a privately held custom home builder and design-build firm founded in 2003 by Shawn Cayer and headquartered at 16 Market Street, Ipswich, Massachusetts. The firm serves high-net-worth residential clients across the Greater Boston region, the North Shore, coastal Maine, and coastal New Hampshire, and is organized into four integrated service branches: custom home building (new construction, additions, renovations, including historic restorations); Windhill + Co. Woodworks, a custom cabinetry and millwork operation with a full-service showroom, manufacturing shop, and finishing facility in Georgetown, MA; Windhill Realty, a boutique real estate agency focused on site selection and property discovery; and Windhill + Co. Whole Home Services, which provides ongoing property maintenance and small projects. Core technical capabilities include in-house custom woodworking that combines traditional hand-made joinery with modern manufacturing methods, 3D CAD renderings and shop drawings used to translate concepts into build-ready documentation, and ProCore project management software for scheduling, subcontractor coordination, and client reporting.

The business generates revenue primarily through one-time project-based contracts for custom home construction, renovations, and cabinetry work, supplemented by professional services revenue from the realty and whole home maintenance divisions. Pricing is quote-based and not publicly disclosed, with free consultations offered to assess project fit. The go-to-market is sales-led, driven by Shawn Cayer's direct relationships with HNW homeowners and a network of repeat clients and personal referrals, supported by a portfolio website, a Fieldnotes content blog, email newsletter, and active presence on Facebook, Instagram, Pinterest, LinkedIn, and X. Long-standing collaborative relationships with regional architects and designers, notably Cummings Architects + Interiors, are a core channel for both project leads and preferred-vendor cabinetry work. The company has received multiple industry recognitions, including two Chrysalis Awards (historic renovation and whole-house remodel), Best of Boston Home (Custom Home Design/Build North), and editorial features in This Old House, House Beautiful, and Northshore Home Magazine.

• William Raveis Real Estate: Large Northeast-focused residential real estate brokerage serving affluent New England markets including the North Shore and coastal Connecticut/Massachusetts. Comparable as a real estate services incumbent operating in Windhill's geographic territory, but at significantly larger scale with Windhill's boutique realty as a niche alternative.

Emerging players

• Cumar Marble & Granite: Massachusetts-based custom stone and surface fabrication serving luxury residential projects and architects in the Boston area. Comparable as a supplier/vendor ecosystem participant in the high-end custom build market, often specified on projects like Windhill's.

Others
