What THOMAS PORTER ARCHITECTS, INC does

Thomas Porter Architects, Inc. is a privately held architecture firm founded in 2009 and headquartered in Toledo, Ohio, with a secondary office in Dayton. The firm offers a unified service model spanning three core disciplines: architecture, interior design, and planning. Its portfolio is heavily weighted toward historic preservation, adaptive reuse, sustainable design, and ADA/code compliance, with marquee projects such as the Hensville entertainment district (Toledo Mud Hens), the Toledo School for the Arts addition, the Westminster Presbyterian Church renovation, the Mennel Milling Company corporate headquarters, and the Continental Baking Co. (Wonder Bread) building. Project budgets disclosed range from $560,000 to $8.5 million, and building sizes from 2,700 to 70,000 square feet.

The firm generates revenue through project-based professional services billed to clients across four primary verticals: government and public sector agencies (Ohio State Highway Patrol, Erie Metroparks, Wood County Board of DD), educational institutions (Toledo School for the Arts, Maumee City Schools), commercial real estate developers (Toledo Mud Hens, Toledo Revival/Hotel Royal), and historic property owners. Pricing is project-based, varying with scope and complexity, with no standardized tiers publicly disclosed. The firm has demonstrated specialized expertise in administering Federal and State Historic Tax Credit Programs and National Park Service compliance, securing over $7.7M in historic tax credits for the Hensville project alone. The go-to-market motion is enterprise project-based sales via direct project inquiries, business development, and established client relationships in the Northwest Ohio region.

Thomas Porter Architects is led by three principals: Julie Apt (finance & human resources), Andy Knopp (business development), and Andrew Hofbauer (operations & technology), supported by a team of approximately 10 members including architects, designers, and administrative staff. The firm maintains stable recurring partnerships with engineering firms (MDA Engineering, LKL Engineers, JDRM) and general contractors (Turner Construction, A.A. Boos & Sons) across its projects. Marketing relies primarily on a project portfolio website, LinkedIn/Facebook/Instagram presence, and earned media in regional outlets such as the Toledo Blade and Toledo City Paper. The firm is privately held with no disclosed external institutional ownership or fundraising activity.
