A barndominium costs $65 to $160 per square foot to build, or $130,000 to $320,000 on average for a 2,000-square-foot home, on HomeGuide’s latest figures (January 2026)1. Angi publishes a $230,000 average, with a small simple build from $112,800 and luxury builds to $540,000 (March 2026)2, and HomeAdvisor’s metal-home page prices the barndominium type at $20 to $85 per square foot, averaging $53 (June 2026)3 — different scopes and page labels, each presented as published. Angi and HomeAdvisor are corporate siblings, and matching figures alone don’t establish independent corroboration. The figures below are the latest published data from each source.
Cost by size
HomeGuide’s table is the total cost to build, excluding land1:
| Square feet | Average cost to build (HomeGuide) |
|---|---|
| 1,000 | $65,000–$160,000 |
| 1,200 | $78,000–$192,000 |
| 1,500 | $97,500–$240,000 |
| 1,800 | $117,000–$288,000 |
| 2,000 | $130,000–$320,000 |
| 2,500 | $162,500–$400,000 |
| 3,000 | $195,000–$480,000 |
| 3,500 | $227,500–$560,000 |
| 4,000 | $260,000–$640,000 |
| 5,000 | $325,000–$800,000 |
Angi’s table is labeled average price ranges for standard kit sizes: 30×40 (1,200 sq ft) $112,800 to $144,000, 40×60 (2,400 sq ft) $225,600 to $288,000, 40×75 (3,000 sq ft) $282,000 to $360,000, 60×60 (3,600 sq ft) $338,400 to $432,000, 60×70 (4,200 sq ft) $394,800 to $504,0002. Angi’s ranges are narrower than HomeGuide’s at the overlapping sizes — its $112,800 to $144,000 for 1,200 square feet falls entirely inside HomeGuide’s $78,000 to $192,000 total for that size — and the tables carry different labels (standard kit sizes vs total cost to build), presented as published12.
Kit prices and build methods
HomeGuide splits the kit from the finished build: a barndominium kit with assembly runs $30 to $50 per square foot — the prefab kit itself at $20 to $35 per square foot for plans and shell materials, plus $10 to $15 per square foot for on-site assembly labor — and none of that includes site prep, foundation, utilities, or interior finishes1. Its kit table by dimensions (kit plus assembly, unfinished)1:
| Dimensions | Sq ft | Unfinished kit cost (HomeGuide) |
|---|---|---|
| 30×40 | 1,200 | $36,000–$60,000 |
| 40×40 | 1,600 | $48,000–$80,000 |
| 40×60 | 2,400 | $72,000–$120,000 |
| 40×70 | 2,800 | $84,000–$140,000 |
| 50×50 | 2,500 | $75,000–$125,000 |
| 50×80 | 4,000 | $120,000–$200,000 |
| 60×60 | 3,600 | $108,000–$180,000 |
| 60×80 | 4,800 | $144,000–$240,000 |
Angi frames the same choice by build method2:
| Build method (Angi) | Material costs | Labor costs |
|---|---|---|
| Build from scratch | $25,450–$102,700 | $29,000–$58,000 |
| DIY barndominium kit | $20,000–$90,000+ | $85–$95 per sq ft for specialized work |
| Kit with professional assembly | $20,000–$90,000+ | $25,000–$50,000 |
HomeAdvisor’s page is labeled for metal homes; its only explicitly barndominium figures are the type-table row at $20 to $85 per square foot, averaging $53, and its remaining figures stay on the metal-home label and aren’t transferred here3. The three publishers scope kits differently — HomeGuide per square foot, Angi by build method, HomeAdvisor by home type — presented as published123.
Plans
Stock barndominium plans cost $1,300 to $2,000, and custom-designed plans $4,500 to $6,000 or more, on HomeGuide; a middle option it describes is paying an architect or designer to modify a stock plan1.
Where the money goes
HomeGuide’s breakdown of a build budget, as percentages of total cost1:
| Factor | Share of total (HomeGuide) |
|---|---|
| Building shell / kit | 20% |
| Assembly labor | 10% |
| Site prep | 5%–10% |
| Concrete slab foundation | 5%–10% |
| Utilities | 15% |
| Interior & exterior finishing | 40% |
| Permits | <1% |
Foundation
HomeGuide prices the typical concrete slab foundation at $6 to $14 per square foot, with a basement foundation raising costs to $35 to $50+ per square foot before finishing the basement interior1. Angi prices foundation work at $4,000 to $12,500 on its labor list — a lump-sum framing against HomeGuide’s per-square-foot one, presented as published12.
Labor
Hourly rates, both publishers: HomeGuide lists a general contractor at $50 to $150 per hour, interior designer $50 to $200, electrician $50 to $130, plumber $45 to $1501; Angi instead puts the general contractor at 10% to 20% of total project cost, with an architect at $125 to $250 per hour, interior designer $50 to $200, electrician $50 to $100, and plumber $180 to $5002. The plumber rates diverge sharply — $45 to $150 against $180 to $500 per hour — presented as published with no stated cause12. Angi’s per-task labor estimates2:
| Task | Labor estimate (Angi) |
|---|---|
| Foundation | $4,000–$12,500 |
| Insulation | $1,100–$2,400 |
| Plumbing | $400–$1,900 |
| Sewer and septic | $2,000–$9,500 |
| Electrical | $600–$2,200 |
| HVAC | $2,600–$13,500 |
| Roofing | $5,400–$10,700 |
| Flooring | $7,000–$28,500 |
| Drywall and interior | $5,000–$30,000 |
Interior finishing
HomeGuide’s interior build-out figures: drywall $1.50 to $3.50 per square foot, spray foam insulation $1.50 to $5.00 per square foot of surface area, flooring $4 to $15+ per square foot installed, interior painting $1 to $6 per square foot, HVAC $7,000 to $16,000 with ductwork, a furnace with ductwork $3,500 to $7,500+, interior doors $155 to $688 each, exterior doors $300 to $1,900 each, a full kitchen appliance set $2,500 to $6,800 installed, and kitchen cabinets $4,500 to $15,0001.
Land, site prep, and utilities
HomeGuide puts developing a rural lot — utilities, clearing, road access — at up to $75,000, with a land survey at $200 to $1,200, clearing at $1,200 to $8,000, and roads per square foot: asphalt $5 to $12+, gravel $4 to $101. Angi prices land itself at $2,000 to $500,000+, averaging $75,000, clearing at $1,398 to $6,176, and roads per linear foot: asphalt $70 to $170, gravel $14 to $25 — the road figures carry different units (per square foot vs per linear foot) and aren’t directly comparable, presented as published12. On utilities, HomeGuide prices adding services to a vacant lot at $9,000 to $34,500+, with a well at $30 to $80+ per foot drilled, a sewer line $1,600 to $7,200 for up to 40 feet, septic $3,500 to $8,500, overhead power $5 to $15 per square foot or underground $10 to $25, interior wiring $6,000 to $22,500, and rough-in plumbing $4 to $6 per square foot1; Angi’s labor list puts sewer and septic work at $2,000 to $9,500, within its own scope2.
Permits
Permit requirements and fees vary by municipality, so confirm with your local building authority before budgeting. HomeGuide publishes $500 to $2,000 for building permits, while Angi publishes $1,200 to $2,000 — a narrower low end, presented as published12.
Exterior finishing
HomeGuide’s exterior figures: siding $3 to $13 per square foot, a driveway $3 to $12 per square foot, a concrete patio $4 to $12 per square foot, a deck $25 to $50 per square foot, and fencing $20 to $60 per linear foot installed1.

Barndominium vs. traditional house
HomeGuide’s own comparison, its framing: a barndominium at $130,000 to $320,000 against a traditional house at $155,000 to $416,000, with a build time of 6+ months against 12+, and a lifespan of 50+ years against 70 to 100+1. Angi separately publishes a 50-to-150-year lifespan range for barndominiums — a wider top end than HomeGuide’s 50+, presented as published12.
Timeline
Building a barndominium takes around six months, or longer for larger and more customized homes, on HomeGuide1.

The bottom line
Budget $65 to $160 per square foot to build on HomeGuide’s figures, $130,000 to $320,000 for a 2,000-square-foot home before land; Angi’s average lands at $230,000 with its own low-to-high span of $112,800 to $540,000. The kit is the smaller line: $30 to $50 per square foot with assembly on HomeGuide, leaving site prep, foundation, utilities, and the interior and exterior finishing that its budget breakdown puts at 40% of the total. Ask each builder to state exactly what its kit or shell quote includes — the sources scope those quotes differently throughout.
