What KBS Builders does
KBS Builders, Inc. is a New England modular construction manufacturer founded in 2001 and headquartered in South Paris, Maine. The company designs and factory-builds residential single-family homes (ranches, capes, colonials, ADUs, custom luxury) and commercial/multi-family structures (apartments, townhomes, senior housing, workforce and affordable housing, hotels, retail) using a controlled, off-site panelized and volumetric modular process. KBS operates two production facilities in South Paris and Oxford, Maine, totaling over 150,000 sq. ft. with a combined throughput capacity of 10-12 modular units per week per factory, leveraging Hundegger CNC precision saws and Cadworks CAD design software, with capabilities to certify buildings to LEED, ENERGY STAR, Net Zero, and Passive House standards. The product portfolio was broadened in 2024 with standalone Panelized Wall Assembly components, and the company launched KBS Logistics in 2025 to internalize delivery of completed units to project sites.
KBS's revenue model is primarily project-based manufacturing contracts (one-time license/sale of completed units to developers, builders, and general contractors, with recent multi-unit contracts ranging from $2.1M to $4.2M), supplemented by in-house engineering and plan customization services (stamped architectural, structural, mechanical, and electrical plans) and the newly formed KBS Logistics arm. Pricing is not publicly disclosed and is quote-based per project, scaled by unit count, square footage, and customization. The go-to-market is sales-led and channel-partner-driven: an in-house sales team engages licensed builders, developers, and general contractors across New England, supplemented by a Building Partner Network through which qualified project leads are referred to vetted licensed contractors. Customers include private mid-market developers (Zachau Construction, Portland mixed-income developer, Bowdoinham townhouse developer, Dooryard LLC) and government/affordable-housing entities (MaineHousing, Town of Rumford, Boothbay Regional Development Corporation), with named project awards across Maine and New Hampshire through 2026.
KBS is a privately held, wholly owned subsidiary of Star Equity Holdings, Inc. (a public holding company), operating within its Building & Construction division under President Thatcher Butcher. The company has built more than 3,000 homes across New England since 2001 and currently serves Maine, New Hampshire, Massachusetts, Connecticut, Rhode Island, and Vermont. The primary regulatory risk is Maine's LD 2229 code interpretation, which died in committee and has placed approximately 246-300 planned multifamily modular units in regulatory limbo across Maine.
