Barndominium or Custom Home in Florida?
Barndominiums and traditional custom homes can both work in Florida, but both must meet the Florida Building Code's wind requirements.
Price per square foot varies by county, site, wind zone, finishes and builder, so compare real bids rather than published averages.

JRH guiding principles are: Engineering Excellence. Delivered on Time. Built on Value.
Key Differences
Framing: barndominiums often use steel or pre-engineered metal building (PEMB) frames; custom homes often use wood framing or concrete block (CMU)
Interior space: steel frames allow tall ceilings and wide clear spans with fewer bearing walls
Openings: large barndominium doors and windows need wind-rated products matched to design loads
Foundations: both need a foundation matched to soil, flood zone and wind uplift
Florida Wind Code Checklist
Confirm the site's design wind speed and exposure under the adopted code
Check whether the site is in the High-Velocity Hurricane Zone (HVHZ), which covers Miami-Dade and Broward counties
Verify roof, door and window products carry wind ratings that meet the design loads
Provide a continuous load path from roof to foundation
Confirm flood zone and finished floor requirements

Challenges
Every roof, door and window product needed a wind rating that met or exceeded the home's calculated design loads
Framing and foundation design had to support that wind-resistant envelope
Objectives
Deliver complete structural plans for Florida wind-resistant construction.
Verify product compliance against the design loads.
Solutions JRH Engineering Provided
Structural engineering foundation and framing package
Design loads calculated and checked against the rated limits of the specified roof, door and window products
Wood species and grades specified throughout the framing

Another Example: Arcadia, FL
On a CMU masonry custom home in Arcadia, JRH designed a concrete block home for a 148 mph basic wind speed with Exposure D under ASCE 7-22 and the FBC 8th Edition.
