A 50×50 barndominium gives you 2,500 square feet in a perfectly square footprint — a roomy family home with a shape that’s unusually easy to lay out. Fifty feet in both directions means no long, narrow compromises: you get a deep, wide interior that designers can wrap around a central kitchen and living core, with bedrooms tucked to the corners. It slots neatly between the ever-popular 40×60 and the larger 50×60, and it’s a great choice for buyers who want a genuine three- or four-bedroom home without going oversized.
This guide covers what a 50×50 costs to build in 2026, floor plans that fit the size, popular ways to lay out 2,500 square feet, and how to finance it.
How much does a 50×50 barndominium cost?
The figures below are calculated from the per-square-foot rates in our barndominium cost guide, where you’ll find the full breakdown and a calculator. Here’s how a 50×50 (2,500 sq ft) shakes out in 2026:
| Build type | Cost per sq ft | 50×50 (2,500 sq ft) |
|---|---|---|
| Kit materials only | $20 – $35 | $50,000 – $87,500 |
| Shell, erected | $30 – $50 | $75,000 – $125,000 |
| Finished — standard finish | $80 – $120 | $200,000 – $300,000 |
| Finished — high-end | $150+ | $375,000+ |
The shell is only 20–40% of a finished build; the rest is the slab, interior framing, mechanicals, insulation, and finishes. Most owner-directed 50×50 builds come in around $200,000–$300,000 at a standard finish. If you’re pricing a kit, remember it covers the shell only; budget the interior separately.
Best 50×50 barndominium floor plans
A true 2,500 sq ft square plan is a little less common than the popular rectangular sizes, so the three below bracket the size — from a compact two-story to a larger loft design — and any of them can be customized to a square 50×50 footprint. All are complete, buildable plan sets, and most fit the 3-bedroom to 4-bedroom range.
SV-5501 Charlotte — 3 bed / 2 bath + garage (near-square)
2,400 sq ft heated · 56’×58′ (near-square) · single story · 3 bedrooms, 2 baths · 1,120 sq ft attached garage · 9′ ceilings · $849.99
The closest to a true 50×50 of the group. Charlotte’s near-square footprint delivers an open-concept three-bedroom home with a big attached garage and a mudroom — a practical, everyday single-story that suits the square shape beautifully.
PL-62513 Harper — 3 bed / 2 bath, two-story
2,132 sq ft heated · 60’×50′ · two story · 3 bedrooms, 2 baths · 620 sq ft porch · $849.99
A compact, efficient two-story on a near-50×50 footprint. Harper stacks its living up rather than out, so it fits three bedrooms and a full living core on a smaller slab — a smart choice for a tighter lot or a lower foundation cost.
SV-5504 Azalea — 3 bed / 2 bath, two-story with loft (size up)
3,058 sq ft heated · 50′ wide · two story · great room with wood stove · loft via spiral staircase · rear porch with outdoor kitchen · $1,349.99
If you want to stretch beyond 2,500 sq ft, Azalea keeps the 50-foot width and adds a second story and a loft for a little over 3,000 sq ft of character-filled living — a great option when you love the square footprint but want more room.

Popular 50×50 layout ideas
A square 2,500 sq ft footprint is one of the most flexible shapes to design.
Central living core. Put the kitchen and great room in the middle of the square with bedrooms in the corners — the square shape makes this natural and keeps everything a short walk apart.
Split-bedroom family plan. Place the primary suite on one side and the secondary bedrooms on the other, with living space between — easy privacy in a compact footprint.
Three or four bedrooms. 2,500 sq ft comfortably fits three bedrooms plus an office, or a full four-bedroom layout for a growing family.
Go two-story. Stacking living (like the Harper or Azalea) keeps the foundation and roof smaller and can lower cost per square foot while adding bedrooms upstairs.
Advantages and disadvantages of a 50×50 barndominium
Advantages
- A flexible square footprint that’s easy to lay out around a central core
- Roomy 2,500 sq ft — comfortable 3–4 bedroom family home
- Wide 50-foot span opens up layouts a narrow build can’t do
- Still well below the cost of going truly large
Disadvantages
- Exact square stock plans are less common — you may customize
- Needs a wider, more level lot than a 30- or 40-foot-wide build
- More to build and finish than the popular 40×60
Other costs to consider
Beyond the kit and finishes, budget for land, site prep and a slab (plus septic and a well on rural land), utility hookups, and interior finishes. These apply at every size — our cost guide breaks them down line by line.
Financing a 50×50 barndominium
