What allen designs does
Allen Designs is a privately held consulting structural engineering firm founded in June 1987 by T. William (Bill) Allen in Mission Viejo, California. The firm specializes in the structural engineering of wood-framed structures, with a focused practice in residential remodeling (active for the past 15+ years) alongside commercial buildings, hospitality hotels and restaurants, medical office buildings, and churches. It serves clients including homeowners, contractors, developers, and government entities across California (Orange County, San Diego County) and Arizona (Phoenix metropolitan area), with completed projects in Utah and New Mexico. The firm invests in constructability-focused deliverables, employing a "calc and fit" methodology in which all plans and details are drawn to scale and using proprietary finite element analysis techniques for existing footing modeling and shear wall analysis that reduce required underpinning and hold-downs compared with traditional methods.
The firm operates three offices — Mission Viejo (Orange County, CA), Oceanside (San Diego County, CA), and Phoenix (AZ) — and is led by a principal engineer who holds California Civil Engineer (1980), California Structural Engineer (1984), and Arizona Professional Engineer (Structural) (1996) licenses. Its technology stack is conventional engineering tooling: AutoCAD for detailing (since 1990), Revit for structural coordination (since 2008; reverted to AutoCAD for primary detailing in 2016 due to precision limitations on residential remodeling work), RISA 3D for three-dimensional structural analysis, and Microsoft Excel for calculations. Proprietary analytical templates for finite element analysis of existing footings and shear walls with openings differentiate the firm from competitors using traditional 45-degree load distribution methods.
The business model is professional services: project-based, quote-driven structural engineering fees billed against multi-year contracts, with no product or SaaS revenue stream. There is no external investment, no parent company, and no institutional ownership — the firm is fully owned and operated by the founder-principal. Revenue is not publicly disclosed, and the firm employs roughly 15 people. Distribution is direct sales through a project-portfolio website (allendesigns.com) and direct client engagement, with no formal partnerships, channel relationships, or marketing automation in evidence.
