What Wirth & Company Construction does

Wirth & Company is a family-owned custom home builder founded in 2005 and headquartered at 135 Springs Fireplace Road, East Hampton, New York. The company was established by Jonathan Wirth and his father Walter Wirth, combining Walter's 50+ years of construction trade experience (rooted in East Hampton since the mid-1980s via Walter Wirth Builders) with Jonathan's 20+ years of project execution and construction management training from Wentworth College in Boston. Over 17+ years the business has grown to over 90 in-house employees and serves high-net-worth homeowners across The Hamptons sub-markets including East Hampton, Amagansett, Sag Harbor, Montauk, Water Mill, and North Haven. Core service lines are custom new-home construction, high-end renovations (including structural changes, finish work, and custom millwork), and construction management services covering project management, budgeting, subcontractor coordination, quality control, and safety compliance. Project management, budgeting, and field reporting run on Procore, the only disclosed technology dependency; no proprietary software, AI/ML capabilities, or patents are referenced.

The company derives revenue from one-time custom home builds and high-end renovations delivered under quote-based pricing tied to scope, materials, and specifications, plus construction management services billed as professional services. Its primary customer segment is affluent homeowners seeking luxury residential construction in The Hamptons, with secondary engagement through architect and designer collaborations (named partners include Jason Thomas, Anne Sherry, Fleetwood McMullan and Sanabria, Spring Architecture Design, and AD100 designer Hadley Wiggins). Go-to-market relies on enterprise field sales with a relationship-driven motion: portfolio showcasing on the company website, an active Instagram presence (@wirthandcompany), repeated editorial features in Hamptons Cottages and Gardens (July and August 2025 covers) and Architectural Digest (July/August 2026), architect/designer referrals, and word-of-mouth from a base of hundreds of clients accumulated over 17+ years. Marketing channels are top-of-funnel content and earned-media, with architect/designer partnerships functioning as mid-funnel referral generation.

Ownership and governance are founder-led and multi-generational, with no disclosed external institutional investors or parent company. Jonathan Wirth serves as Co-Founder and Principal Owner; Walter Wirth serves as Co-Founder, Project Manager, and Consultant; Emma Field (Walter's daughter) is Financial Officer with prior international marketing experience at MINDBODY; Derek Field (Jonathan's brother-in-law) is Jr. Partner and Senior Project Manager; and Sawyer Wirth (Jonathan's cousin) is a Project Manager. The company is currently hiring across field, administrative, and project leadership roles, signaling workforce expansion against active project demand. Pricing is not publicly disclosed, revenue is not disclosed, and the legal entity type is unstated, though the business operates as a private, family-controlled US entity domiciled in New York.

Broad incumbents

• KB Home: National homebuilder focused on entry-level and first move-up buyers. Broad incumbent in U.S. residential construction; comparable at the industry level but not a direct competitor for Hamptons luxury custom work.
• Smith Douglas Homes: U.S. homebuilder with luxury and move-up offerings in select Southeast and Mid-Atlantic markets. Adjacent to Wirth at the broad industry level; both operate in luxury residential construction but in different geographies and at different scales.
• Brookfield Residential: Master-planned community and luxury homebuilder operating in select U.S. markets. Adjacent to Wirth's high-end custom positioning in coastal/affluent U.S. geographies, but at much larger scale and with a community-development model.
• M/I Homes: Public homebuilder with luxury and move-up product across multiple U.S. regions. Comparable only at the broad industry level; Wirth is a single-market Hamptons custom builder while M/I operates as a regional production homebuilder.
• PulteGroup: Large national homebuilder with a Centex/Pulte/Del Webb portfolio spanning entry-level through luxury. Relevant as a broad incumbent competing for high-end residential demand and as a benchmark for operational scale and capital structure in U.S. homebuilding.
• Tri Pointe Homes: Public homebuilder with luxury and move-up brands including a coastal presence. Comparable as a broad incumbent in the U.S. luxury residential market, though Wirth is a single-market custom specialist.
• Toll Brothers: National publicly traded luxury homebuilder with a deep move-up and luxury product line. Comparable as a competitor for high-end custom and luxury residential construction in affluent U.S. geographies, though Wirth is a bespoke Hamptons specialist while Toll operates at much greater scale and breadth.
• DR Horton: Largest U.S. homebuilder by volume, including luxury product via its Emerald Homes brand. Comparable only at the broad industry level—Wirth is a boutique Hamptons custom builder while Horton is national production—but useful as a scale reference.
• M.D.C. Holdings (MDC Holdings / Richmond American): National homebuilder (now under Sekisui House) with luxury and move-up product. Comparable only at the broad industry level; useful as a benchmark for luxury-segment positioning in U.S. residential construction.

Regional players

• Coastal Construction Group: Florida-based luxury and high-end commercial general contractor serving affluent coastal clients. Comparable business model—craftsmanship-led, relationship-driven custom construction for HNW clients—but operates in a different geography than Wirth's Hamptons focus.
