Allen & Hoshall in Chattanooga: A Large-Scale Architectural Firm Spanning Healthcare, Corporate, and Civic Design

Allen & Hoshall is a full-service architecture and engineering firm based in Chattanooga that has operated continuously since 1945, making it one of the longest-established design practices in the region. The firm maintains around 150 staff members across multiple offices and specializes in healthcare, corporate workplace, education, and civic infrastructure projects, with particular depth in designing medical facilities and large institutional buildings.

What Allen & Hoshall Actually Is

Allen & Hoshall operates as a mid-to-large regional firm rather than a boutique practice. It combines architectural design with in-house engineering disciplines, meaning clients can coordinate structural, mechanical, electrical, and plumbing systems without assembling a separate consultant team. The firm holds multiple professional licenses across states and works on projects ranging from $5 million to over $100 million in construction value. Unlike smaller practices that may focus on residential or single-building types, Allen & Hoshall's model emphasizes repeat relationships with institutional and corporate clients who need both initial design and long-term advisory capacity.

Services and Project Types

Allen & Hoshall's portfolio breaks into several major categories. Healthcare design represents a significant portion of work: hospital expansions, surgical centers, outpatient clinics, and medical office buildings. Corporate workplace projects include office renovations, manufacturing facilities, and campus master planning. Education work spans university buildings, K-12 facilities, and research spaces. Civic and institutional projects include municipal buildings, courthouses, and cultural facilities.

The firm's engagement model typically operates on a percentage-of-construction-cost basis for design services, which is standard in the industry. For a $10 million project, design fees typically range from 4 to 8 percent of construction cost, depending on complexity and scope. Projects involving medical systems or research facilities—which require specialized coordination—sit at the higher end. The firm also offers services like feasibility studies, master planning, and construction administration, which may be priced as separate line items or as part of a full design contract. Specific fees should be confirmed directly, as they vary by project scope and market conditions.

How Allen & Hoshall Compares to Other Chattanooga Architects

Chattanooga's architectural landscape includes both smaller, design-focused firms and larger national practices with local offices. Firms like Chambliss Architects and Bockus Payne Architecture operate at smaller scale, typically serving local clients on projects under $20 million and offering more direct principal involvement on individual projects. Those practices suit clients seeking deep relationships and hands-on design leadership on smaller institutional or cultural buildings.

Allen & Hoshall's advantage lies in its capacity for large, complex projects and institutional repeat work. A healthcare system planning a multi-building clinical campus, or a municipality undertaking a major civic center renovation, gains from the firm's existing relationships with building departments, code officials, and specialty consultants in those sectors. For clients with straightforward, smaller-scale projects, however, the firm's size and institutional focus mean less flexibility in pricing or timeline than a smaller practice might offer.

National firms with Chattanooga offices, such as AECOM or Jacobs, compete at similar scale but bring national resources and standardized processes; they suit organizations seeking a firm with global benchmark data. Allen & Hoshall's regional rootedness and local institutional knowledge offer a different advantage.

Who Allen & Hoshall Suits and Who It Does Not

The firm is well-suited to healthcare systems, universities, large municipal governments, and corporations planning multiyear facility strategies. Organizations that need repeated, long-term advisory relationships—such as a hospital planning multiple expansions over a decade—benefit from established relationships and institutional memory. Similarly, projects requiring deep knowledge of local building departments, code history, and regional construction practices align with Allen & Hoshall's profile.

The firm is a poor fit for a small business seeking one modest renovation, a homeowner planning a residential project, or a client with a tight budget and limited schedule flexibility. Single, small-scale projects do not leverage the firm's institutional strengths and may be more efficiently served by smaller local practices or by a client's in-house team.

What the First Engagement Involves

Initial conversations typically begin with a feasibility or programming phase. The firm will assess the client's goals, budget, timeline, and site constraints; produce a preliminary cost estimate and schedule; and often develop a master plan or strategic facility roadmap. For repeat clients, this phase may be informal and brief. For new relationships, the firm typically produces a written feasibility report that guides the design phase.

Formal engagement involves a signed contract defining scope, fees, schedule, and decision-making roles. The client designates a project manager or steering committee; Allen & Hoshall assigns a project architect and consulting engineer team. Regular meetings—typically bi-weekly during design—track progress against the agreed schedule.

Hours, Location, and Logistics

Allen & Hoshall's main office is located in downtown Chattanooga. The firm operates standard business hours, Monday through Friday, 8 a.m. to 5 p.m. Project meetings may be held at the client's site, the firm's office, or via video conferencing, depending on project phase and client preference.

Parking at the downtown office is available on-street or in nearby lots; clients attending in-person meetings should confirm specific arrangements with their project manager.

Allen & Hoshall's 80-year tenure in Chattanooga and focus on institutional and corporate work make it a reliable choice for large, complex projects requiring local expertise and ongoing design partnership.
