Start With the Design and Permitting Package
Most post frame builds stall in the same place: nobody has priced your exact building, on your exact lot, with your county's rules. This package does that work first, so the number you sign is real.
Your lot run against zoning and setback rules before you spend on a full design.
Building placement, access, and clearances worked out for your property.
Size, layout, doors, and finishes locked on a design sheet you approve.
Engineered drawings stamped for your build, ready for the county.
Drawings, checklist, and application prep, so filing is not a second project.
$2,500 flat. Credited in full toward your 40% first draw.
This is not an extra charge. It is the deposit you were going to pay anyway, applied to your build. It is nonrefundable if you do not move forward.
The package covers design, plan review, and permit application prep. It does not include county permit fees, plan review fees, or the post frame build itself. Change orders are extra.
WB Exterior Solutions | St. Peters, MO. The fit check is a planning aid based on your jurisdiction's published rules, not a permit guarantee; your packet includes the parcel verification checklist for your specific lot.

Straight Answers
Do I need a permit for a post frame building in Warren County?
Yes, in most cases — and the Design & Permitting Package handles it. It includes the stamped Missouri engineering plans, the drawings and the permit run for your Warren County build, so you do not have to manage the county paperwork yourself.
How long is it from deposit to dried-in in Warren County?
Engineering and kit lead times run several weeks, which is exactly why build slots are reserved in order. Once materials are on site, most shells go up and are dried-in in a matter of days, with the exact timing confirmed at your site visit.
Can you build through winter in Warren County?
Yes. WB builds shells through winter. The shell itself can be erected in cold weather; concrete work is weather-dependent and is scheduled around conditions.
What site prep do I need in Warren County?
A level pad where the building will sit, confirmed at your site visit. WB verifies your satellite measurements on site before erection.
Do you finish the inside as living space in Warren County?
No. WB builds shells — the starting point for storage, shop and equipment space. Interior living-space finishing is a separate trade step, not part of a WB shell.

Post Frame Tax Timing Worksheet
How you classify the building, and the year it is placed in service, can move your first-year deduction from a small slice to the full contract price. Run your numbers, then confirm with your CPA.
Standard path: 39-year straight line
Straight-line over 39 years. Half-year convention ignored, so year one is approximate.
Accelerated path: Section 179 (agricultural use)
Subject to business income limits, annual dollar caps, and placed-in-service rules. The deduction cannot exceed your business taxable income for the year.
Estimate only, not tax advice. Eligibility depends on how the building is used and when it is placed in service. Confirm with your CPA before December 31.
