Horizon Design and Detailing bridges the gap between commercial real estate due diligence and structural execution.

Founded on a 40-year foundation of commercial architecture and Structural Steel construction, our firm serves high-velocity franchisee’s, retail developers, and steel fabricators nationwide.

We operate two highly specialized, interconnected divisions built for speed and precision. Our Due Diligence Division delivers elite, Experience-backed Site Investigation Reports (SIRs) within a Standard 72-96 hour window, identifying critical zoning, utility, architectural, fire suppression, on-site parking, drive through stacking, landscaping requirements and permitting processes before a lease is signed. Our Structural Detailing Division translates complex designs into flawless, fabricator-ready shop and erection drawings.

At Horizon, we don’t just cross-reference local municipal codes—we understand the physical mechanics, and structural steel framing of modern commercial prototypes. We identify the challenges, detail the solutions, and protect your development pipeline from site selection to project completion.
