Pennon Construction Company

What Pennon Construction Company does

Pennon Construction Company, Inc. is a full-service commercial general contractor founded in 1999, headquartered in Shoreline, Washington. The firm delivers construction services across four market sectors: Industrial (warehouses, distribution centers, logistics hubs, manufacturing buildings), Office (corporate campuses, operational training centers, professional office buildings), Retail (standalone buildings, multi-phased sites, retrofits, new construction for regional and national retailers), and Tenant Improvement (interior buildouts, space planning, lobby and amenity renovations, office fit-outs). Its service portfolio spans preconstruction planning (feasibility analysis, budget development, cost control, plan review, site planning, scheduling, value engineering) through full construction delivery, executed under a collaborative model with transparency across project phases.

The company operates a horizontal segmentation approach targeting regional and national commercial clients across the Pacific Northwest (Washington, Oregon, and Idaho). Pricing is project-based, quote-driven, and varies by scope, size, and complexity, with no standard published tiers; contracts span multi-year horizons for larger developments. Revenue is generated through negotiated contracts and competitive bids for commercial projects ranging from small tenant buildouts (under 2,000 SF) to large industrial developments exceeding 440,000 SF. Customer engagement is direct: Pennon serves as prime contractor with full client involvement from preconstruction through turnover, supported by a project-based enterprise field sales motion targeting regional developers and commercial clients.

Pennon is privately held and owned by three principals — Spencer Franks, Eric Dormaier, and Mac Sele — who collectively bring over 45 years of industry experience and are directly involved in day-to-day operations including cost control, preconstruction, and jobsite staffing. The firm has no external investors, parent company, or public market presence. Technology infrastructure is not publicly disclosed; the company relies on standard industry delivery with no proprietary software or AI-driven capabilities. Marketing channels are limited to the company website, LinkedIn, Instagram, and direct outreach via phone and email.
