Questions
What is post-frame construction?
Post-frame construction uses vertical posts embedded in concrete to support roofs and walls, eliminating traditional footings. This method allows flexible interior layouts and cost-effective expansion options.
Can I customize building dimensions?
We offer fully customizable sizes, including spans up to 72 feet without interior posts. Our engineers ensure structural integrity for any custom dimension requested.
What materials do you use?
We use pressure-treated Hem Fir posts, Douglas Fir trusses, and 26-gauge steel siding with 40-year warranties. Interior components include insulated wall girts and fiber-reinforced concrete.
Do you handle permits?
Yes, we assist with permit acquisition through local jurisdictions. Our team provides engineered blueprints and coordinates inspections to ensure code compliance.
How long does construction take?
After permit approval, construction typically takes 1-4 months depending on project complexity and weather conditions. We maintain timelines through efficient material sourcing and experienced crews.
Can I add features later?
Our post-frame design allows easy modifications. Clients frequently add windows, doors, or insulation upgrades post-construction without structural reinforcement requirements.
