Post and beam prices range from about $50-$120 per square foot for a structural frame package to $250-$500 or more per square foot for a completed home. The final quote depends on whether it covers only the frame or a finished building, plus timber species, home size, engineering, site access, and regional labor rates.

Assumptions: U.S. pricing for a straightforward design, standard access, and midrange finishes; local quotes vary.
What a Post and Beam Home Usually Costs
For a typical 1,800-square-foot home, a post and beam frame package commonly costs $90,000-$216,000, with an average near $153,000 at $85 per square foot. This package generally includes engineered timber members, joinery or steel connectors, shop drawings, and delivery within the supplier’s normal service area. It does not usually include the foundation, insulation, windows, mechanical systems, or interior finishes.
A weather-tight shell often runs $270,000-$585,000 for the same floor area, averaging about $405,000. A finished custom home can cost $450,000-$900,000 or more before land, landscaping, and financing. These figures assume standard residential quality and a relatively uncomplicated footprint; large spans, steep sites, premium glazing, and custom detailing can push a quote above the high range.
The scope matters more than the label: compare frame-only, shell, and turnkey quotes separately. Some suppliers advertise a low per-square-foot kit price based on floor area, while contractors calculate construction cost using total conditioned space or gross building area. Confirm what area and construction stages the quote covers.
How Timber, Labor, and Delivery Shape the Quote
A construction estimate divides into the frame package, erection work, and the surrounding building work. A frame-only bid may look inexpensive because it excludes costly items such as foundations, weather barriers, roofing, and utilities. The ranges below show common budget allowances for a 1,800-square-foot project, not a substitute for local bids.
| Quote component | Typical range | Unit basis | What changes the charge |
|---|---|---|---|
| Timber frame package | $90,000-$216,000 | $50-$120 per sq ft | Species, grade, spans, joinery, engineering |
| Frame erection labor | $27,000-$90,000 | $15-$50 per sq ft | Crew size, lift access, frame complexity |
| Crane and equipment | $3,000-$12,000 | $1,500-$4,000 per day | Lift capacity, rental duration, travel |
| Foundation and slab | $25,000-$65,000 | $14-$36 per sq ft | Soil, frost depth, slope, basement |
| Roof and exterior enclosure | $55,000-$140,000 | $30-$78 per sq ft | Roof shape, insulation, cladding, windows |
| Plans, engineering, permits | $8,000-$30,000 | $4-$17 per sq ft | Design revisions, code requirements, jurisdiction |
These lines can overlap in a builder’s bundled price, so they should not be added blindly to a turnkey quote. Taxes, utility connections, excavation, and interior work may appear under separate allowances. Ask whether delivery includes unloading and whether the supplier charges for storage or a second trip.
Labor and enclosure can cost as much as, or more than, the visible timber frame. For labor budgeting, a rough calculation is For example, a 5-person crew working 8 hours a day for 5 days at a blended $75-$125 per worker-hour represents $15,000-$25,000 in labor before equipment and travel.
Which Beam Spans, Timber Grades, and Layouts Raise Prices
Span length is a major structural cost driver. A clear span above roughly 20-24 feet may require deeper or engineered beams, additional posts, or a steel component. The extra design and material can add $5,000-$25,000 or more, depending on the roof load, floor use, and location. Snow and wind requirements also affect member sizes, so the same plan may price differently across states.
Timber species and appearance affect the package price. Standard Douglas fir or Southern yellow pine may sit near the middle of the range, while premium cedar, oak, reclaimed beams, or hand-finished surfaces can add 10%-40% or more. Structural grade and moisture specifications should be compared alongside appearance; a rustic finish does not automatically mean a beam is suitable for a particular load.
Building shape also matters. A simple rectangular plan with a straightforward gable roof tends to use fewer complicated connections than a design with multiple wings, valleys, balconies, or intersecting rooflines. A home under 1,200 square feet can have a higher per-square-foot rate because fixed engineering, mobilization, and delivery costs are spread over less area. A design above 2,500 square feet may improve unit pricing, but larger spans and high-end finishes can outweigh that saving.
Get the structural assumptions in writing, especially span, snow load, timber grade, and included connections. A quote based on a 16-foot span or a particular local design load is not directly comparable with one engineered for 24 feet or a heavier roof load.
How Long Frame Installation Takes and What Crews Charge
A pre-engineered frame for a straightforward home may take a crew of four to six workers about 3-7 working days to erect after the foundation is ready and materials are staged. Complex roofs, large frames, remote sites, or weather delays can extend the work to 1-3 weeks. Installation labor commonly falls around $75-$125 per worker-hour when labor, supervision, and contractor overhead are reflected in the rate.
Some frame companies quote erection as a project price rather than an hourly charge. For a 1,800-square-foot frame, $27,000-$90,000 is a reasonable broad allowance at $15-$50 per square foot. The lower end generally assumes a compact frame and easy crane access; the upper end can reflect intricate joinery, a larger crew, travel, or difficult handling.
Foundation readiness is essential. If anchor bolts are misplaced, the slab is out of level, or the site cannot accommodate a crane, crews may lose time or need added equipment. Confirm the tolerances, access width, staging area, and responsibility for unloading before setting an installation date.
Ask whether the erection bid includes the crane, travel, lodging, and weather-delay terms. A low labor-only price can become a higher installed price once those items are added.
Three Sample Budgets for Different Post and Beam Projects
A 900-square-foot detached studio with a basic Douglas fir frame, simple gable roof, and easy truck access might cost $45,000-$90,000 for the frame package, or about $50-$100 per square foot. Erection could add $13,500-$31,500, while foundation, enclosure, and basic utilities may bring the shell to roughly $135,000-$225,000. Plumbing, a kitchen, and finished interiors would increase the total.
A 1,800-square-foot, midrange home with moderate spans and a standard roof could carry a $110,000-$180,000 frame and erection allowance. A complete weather-tight shell may reach $300,000-$500,000, depending on windows, roof material, foundation, and insulation. Turnkey construction with midrange finishes may total $540,000-$810,000, or $300-$450 per square foot, excluding land.
A 2,600-square-foot custom home with several long spans, premium timber, complex rooflines, and a sloped site may have a frame package of $260,000-$390,000 at $100-$150 per square foot. Erection, crane work, and access provisions can add $60,000-$130,000. A finished build could exceed $1.3 million when premium glazing, retaining work, and custom interiors are included.
These examples show why a kit price is not a finished-home budget. Each excludes land and financing; the final figure depends on local bids, design details, and the exact definition of “complete.”
How Regional Labor and Site Access Change U.S. Prices
Construction labor and subcontractor availability vary widely. Major coastal metros and high-cost resort areas may price 15%-35% above a national midrange estimate, while many lower-cost rural markets may come in 5%-20% below it. These differences apply most strongly to labor-intensive work, permits, and delivery; timber pricing may be less affected where suppliers ship nationally.
Remote locations can erase a lower local labor rate. A frame crew traveling several hours may charge mileage, lodging, per diem, and extra mobilization. A crane rental with a long travel distance or a narrow access road may add $1,000-$5,000 or more. Steep terrain can require grading, retaining walls, or specialized lifting, with site work ranging from a few thousand dollars to tens of thousands.
Local building rules affect engineering and inspection costs. Snow-load zones, high-wind areas, seismic requirements, wildfire-resistant exterior details, and energy codes can change plans or specifications. Permit fees commonly range from $1,000-$8,000 for residential projects but can exceed that in high-cost jurisdictions or when multiple reviews and utility permits are required.
Compare estimates from builders who price projects in the same county or nearby market. National per-square-foot figures are useful for early budgeting, but local labor, code, and site conditions determine the buildable price.
Which Extras Are Often Missing From Frame-Only Prices
Removal and disposal are not usually part of a new-frame package, but demolition can add $5,000-$25,000 or more when an old structure must come down. Excavation and grading may cost $3,000-$15,000 on a mostly level lot and substantially more on rock, steep slopes, or sites requiring retaining walls. Utility connections can add $5,000-$30,000 depending on distance and municipal charges.
Windows and exterior doors are another substantial allowance. Standard openings and midrange products might total $20,000-$55,000 for a modest home; large custom glazing can exceed $80,000. Roofing and siding choices also vary: basic asphalt shingles and standard siding can be less expensive than standing-seam metal, premium wood cladding, or stone accents.
Heating, ventilation, plumbing, electrical work, drywall, cabinets, and flooring are often outside a shell quote. Together, these systems and finishes can add $100-$250 or more per square foot, depending on specification and local labor. Allow a separate 10%-15% contingency for design changes and unknown site conditions rather than treating a supplier’s frame estimate as the whole project budget.
Request an exclusions list before comparing a kit or shell price with a builder’s proposal. Clarify foundation, insulation, weather barrier, roofing, glazing, delivery, engineering, taxes, permits, and finish work.
Where to Trim a Post and Beam Budget Without Weakening the Frame
Keep the building footprint compact and the roof geometry simple. Reducing jogs, intersecting ridges, oversized cantilevers, and unnecessary long spans can lower timber, engineering, erection, and roofing charges together. A change in layout that avoids a costly 24-foot clear span may save more than switching to a slightly cheaper timber species.
Choose a structural grade that meets the engineer’s requirements and reserve premium appearance treatments for visible areas. A concealed secondary beam may not need the same finish as an exposed living-room frame. Standard dimensions, locally available species, and ordinary connector details can reduce custom fabrication and shipping costs without changing the design intent.
Compare at least three bids using the same drawings, timber specifications, delivery terms, and scope. Ask suppliers to price erection separately, then check whether the contractor’s insurance, crane, and travel are included. Bundling frame delivery and erection may reduce coordination costs, but only if the combined quote clearly identifies what happens when a schedule delay occurs.
Complete site clearing, access preparation, and staging before the crew arrives when the builder permits it. Avoid making late plan changes after engineering or timber fabrication begins, since revisions can trigger redesign fees, rework, and storage charges. Do not reduce structural members or skip required engineering to save money; changes must be approved by the design professional and comply with local code.
The most reliable savings usually come from simpler spans, stable plans, and comparable bids—not cutting structural specifications. A small upfront design adjustment can prevent larger material and labor costs during construction.
