Five bedrooms is the point where a barndominium stops being a simple rectangle. Up to four bedrooms you can usually run a single hallway down one side and be done. At five, the layout has to start making decisions — where the primary suite sits relative to everything else, whether the fifth bedroom is part of the main block or deliberately separated, and whether you go up rather than out.
The six plans below run from 2,092 to 6,300 heated square feet. That spread matters more than it looks: the smallest fits five bedrooms into less space than many three-bedroom plans use, and the largest is nearly triple it. Every figure here is taken from the plan’s own spec sheet.
How Much Square Footage Does A Five Bedroom House Plan Actually Need?
The honest floor is around 2,000 square feet. PL-62312 Harmony does it in 2,092, and it works because the bedrooms are small and the plan is long and narrow rather than square. Below that you are building bedrooms people will not want to sleep in.
The comfortable range is 3,000 to 3,500 square feet. Four of the six plans here land there, which is not a coincidence — it is roughly what you need for five real bedrooms, three or four bathrooms, a laundry room, and living space that does not feel like a corridor.
Above 4,000 square feet you are buying separation rather than bedrooms. PL-62511 Morgan’s 6,300 square feet does not contain more bedrooms than Harmony’s 2,092. It contains a second living room, a walk-in pantry nearly the size of the kitchen, and enough distance between the upstairs suite and everything else that two households can genuinely coexist.
How Many Bathrooms
Across these six plans the count runs from three to four and a half, and the pattern is consistent: three full baths is the working minimum for five bedrooms, four is the comfortable number, and the half bath matters more than people expect because it keeps guests out of the bedroom wing entirely.
Five bathrooms for five bedrooms is possible but rarely worth it. Each additional full bath adds plumbing runs, fixtures, and square footage that would serve you better as closet or living space. Two teenagers sharing a Jack-and-Jill bath is a normal arrangement, not a compromise.
One Story or Two
Two of these plans go up. The trade is straightforward and worth thinking about before you fall for a layout.
Single story wins on accessibility — no stairs now and none later, which matters if anyone in the household has mobility limits or might in twenty years. It is easier to clean, and mechanical runs are simpler. The cost is land: Megan needs 90 by 72 feet of buildable ground.
Two stories win on footprint. BCO-40052 Michael fits 3,268 square feet onto a 52 by 60 foot pad — the smallest land requirement here by a wide margin, and less than half what Megan needs for roughly the same heated space. Two stories also give you real separation for free, since a floor between bedrooms does more for noise than any hallway will.
If stairs are a concern but you want the footprint savings, put the primary suite on the ground floor and the secondary bedrooms up. Both two-story plans here do exactly that.
Featured 5 Bedroom Barndominium Floor Plans
Ordered smallest to largest.
PL-62312 Harmony — 2,092 sq ft, the compact option
The smallest five-bedroom plan here by a clear margin, and the cheapest. Harmony fits five bedrooms, three full baths and a half bath into 2,092 heated square feet, plus a 739 square foot shop.
It works because of its shape. At 86 feet wide and only 33 feet deep it is the narrowest plan on this page — essentially a long single-loaded bar, so every bedroom gets an exterior wall and a window without needing a wide building. That is the trade for the compact footage: the plan wants a wide, shallow lot rather than a square one. On a deep narrow lot it will not fit at all.
At 16 feet 1 inch overall it is also the lowest building here, which is worth knowing if you are working under a height restriction or want to avoid a tall gable.
- Heated: 2,092 sq ft
- Shop/garage: 739 sq ft
- Total under roof: 3,541 sq ft
- Footprint: 86′ W × 32′-11″ D
- Beds / baths: 5 bed, 3 full + 1 half
- Stories: 1 · Height: 16′-1″
PL-62307 Sunnyside — 3,063 sq ft with a 969 sq ft workshop
The largest workshop of any plan here, and the reason to choose Sunnyside over the similarly sized Florence. At 969 square feet the shop is a genuine working space rather than a garage, with access from the front porch, the back of the house, and directly from the laundry room — that last door is the detail that makes it usable daily rather than occasionally.
The bedroom arrangement solves the five-bedroom problem neatly. Three secondary bedrooms and the primary suite sit off a rear hallway, and the fifth bedroom is reached from the living room instead, not the hallway. That single change turns it into a guest room, an in-law room or a tenant room without any structural separation — someone can come and go without walking past the children’s rooms.
Single story, three full baths, with a covered front porch spanning the full width. If the workshop is the priority, our barndominium floor plans with shop collection covers layouts built around larger shops.
- Heated: 3,063 sq ft
- Workshop: 969 sq ft · Porch: 461 sq ft
- Total under roof: 4,493 sq ft
- Footprint: 80′ W × 58′ D
- Beds / baths: 5 bed, 3 bath
- Stories: 1 · Height: 21′-11″
GS-8012 Florence — 3,192 sq ft with a self-contained gen-suite
The plan to look at if one of the five bedrooms is really a second household. Florence dedicates one bedroom to a fully self-contained gen-suite with its own living area, kitchenette, private bath and laundry hookups — not a bedroom with a door, an actual small apartment.
That distinction is the whole point. Aging parents, an adult child, or a tenant can run their own day without crossing your kitchen. The suite has its own entrance arrangement, and the remaining four bedrooms sit on the opposite side of the house from the primary suite — two with private baths, two sharing.
Single story, four full baths, 80 by 45 and a half feet, with a vaulted ceiling over the combined living, kitchen and dining space and a patio at the rear. A door connects the primary closet directly to the laundry room. If shared-household living is the driver rather than bedroom count, our multi-generational barndominium plans collection is built around exactly this.
- Heated: 3,192 sq ft
- Total under roof: 3,192 sq ft
- Footprint: 80′ W × 45′-6″ D
- Beds / baths: 5 bed, 4 bath (one bedroom is a gen-suite)
- Stories: 1 · Dormer eave height: 17′
HPZ-26015 Megan — 3,215 sq ft, four and a half baths
The most bathrooms of any plan here — four full plus a half — which in a five-bedroom house means close to one per bedroom without going to the expense of five full baths. If you are housing five people who all leave for work or school inside the same half hour, this is the plan that solves that specific problem.
It also carries a bonus area above the main floor, so the usable space exceeds the 3,215 heated figure without the plan counting as two stories. An 894 square foot garage sits under the same roof.
The cost is land. At 90 feet wide by 72 feet 4 inches deep Megan has the largest footprint on this page — nearly 6,500 square feet of ground for 3,215 heated. Check it against your buildable area and setbacks before anything else. At 29 feet it is also the tallest here.
- Heated: 3,215 sq ft (plus bonus area)
- Garage: 894 sq ft
- Total under roof: 5,481 sq ft
- Footprint: 90′ W × 72′-4″ D
- Beds / baths: 5 bed, 4 full + 1 half
- Stories: 1 with bonus · Height: 29′
BCO-40052 Michael — 3,268 sq ft on the smallest lot
If your land is the constraint, this is the plan. Michael delivers 3,268 heated square feet — 1,880 down and 1,388 up — on a 52 by 60 foot footprint. That is roughly half the ground Megan needs for almost identical heated space, and the smallest land requirement of any plan on this page.
Going up is what buys that. It also buys separation: putting bedrooms on a different floor from the living space does more for noise than any single-story hallway arrangement can. The trade is stairs, and at 25 feet overall it is a tall building for its footprint.
Five bedrooms and three full baths across two floors, with a 529 square foot garage. Three baths for five bedrooms is the working minimum rather than generous, so weigh that against the footprint savings. More two-level layouts are in our 2-story barndominium house plans.
- Heated: 3,268 sq ft (1,880 first floor + 1,388 second)
- Garage: 529 sq ft
- Total under roof: 4,615 sq ft
- Footprint: 52′ W × 60′ D
- Beds / baths: 5 bed, 3 bath
- Stories: 2 · Height: 25′
PL-62511 Morgan — 6,300 sq ft across two floors
Nearly triple Harmony’s square footage for the same five bedrooms, which tells you exactly what the extra space is for. Morgan is 3,150 square feet on each of two floors, and the additional area goes into separation and shared space rather than bedroom count.
The layout departs from the usual barndominium open plan. The family room, kitchen and dining room read as distinct spaces rather than one great room, there is a proper entryway, and the walk-in pantry is nearly the size of the kitchen. Downstairs holds the primary suite, a second bedroom, laundry and a craft room — the craft room is actually larger than that second bedroom, so swapping them is an easy change if you need a bigger secondary.
Upstairs, a balcony overlooks the family room below. Two bedrooms share a bath on one side. Cross the balcony and you reach a hall opening into a second living room, with a large bedroom off it carrying its own walk-in closet and private bath. That upstairs corner functions as an independent apartment — an in-law, an adult child, a tenant, or your own primary suite if you would rather sleep upstairs.
Five bedrooms, four full baths, 70 by 45 feet, no garage.
- Heated: 6,300 sq ft (3,150 per floor)
- Total under roof: 6,300 sq ft
- Footprint: 70′ W × 45′ D
- Beds / baths: 5 bed, 4 bath
- Stories: 2 · Height: 24′-2″
- Garage: none
Choosing Between These Plans
If your lot is the constraint — BCO-40052 Michael needs only 52 by 60 feet. Nothing else here comes close.
If your lot is wide but shallow — PL-62312 Harmony at 86 by 33 feet is built for exactly that shape, and it is the cheapest plan here.
If one bedroom is really a second household — GS-8012 Florence’s gen-suite has its own kitchenette, bath and laundry hookups. PL-62511 Morgan’s upstairs wing achieves the same thing with more space and a second living room.
If you need a real workshop — PL-62307 Sunnyside’s 969 square feet, with the laundry-room door that makes it usable every day.
If bathrooms are the pressure point — HPZ-26015 Megan’s four and a half.
If you want the smallest build that genuinely fits five — Harmony, at 2,092.
How Much Does A 5 Bedroom Barndominium Cost to Build?
Expect between $65 to $160 per square foot for a finished barndominium. The spread comes mostly from interior finish level, your region, and how much work you take on yourself. Going the kit route, the metal shell typically runs $20 to $35 per square foot, with assembly adding $10 to $15 per square foot on top.
Applied to these plans, Harmony at 2,092 square feet lands somewhere between roughly $136,000 and $335,000 finished. Morgan at 6,300 runs from around $410,000 to well past $1,000,000. Those brackets are wide because they are honest — the same plan built by the same crew in two states can differ by half.
Two things push five-bedroom builds toward the upper half of the range specifically. Bathrooms are the most expensive rooms per square foot in any house, and these plans carry three to four and a half of them. And bedroom count drives HVAC — five bedrooms plus living space usually means zoning, which a three-bedroom plan of the same footage often avoids.

Frequently Asked Questions
What is the smallest square footage for a 5 bedroom barndominium?
Around 2,000 square feet is the practical floor. PL-62312 Harmony manages five bedrooms, three full baths and a half bath in 2,092 heated square feet, and it does it by being long and narrow — 86 feet wide by 33 deep — so every bedroom reaches an exterior wall. Below roughly 2,000 the bedrooms get too small to be worth having.
How many bathrooms do you need for 5 bedrooms?
Three full baths is the working minimum and four is comfortable. A half bath matters more than most people expect, because it keeps guests out of the bedroom wing entirely. Five full baths for five bedrooms is possible but rarely worth the plumbing and square footage — two bedrooms sharing a Jack-and-Jill bath is a normal arrangement, not a compromise.
Should a 5 bedroom barndominium be one story or two?
Two stories cut the land you need roughly in half — BCO-40052 Michael fits 3,268 square feet onto a 52 by 60 foot pad. Single story wins on accessibility and simpler mechanical runs, but wants far more ground: HPZ-26015 Megan needs 90 by 72 feet for similar heated space. If stairs are a concern but you want the footprint savings, put the primary suite downstairs and the secondary bedrooms up.
Where should the fifth bedroom go?
Away from the other four, if you can. The most useful arrangement puts the primary suite on one side, three secondary bedrooms together, and the fifth reached from a different part of the house — PL-62307 Sunnyside enters its fifth bedroom from the living room rather than the bedroom hallway. That one change turns it into a guest, in-law or tenant room without any structural separation.
Can a 5 bedroom barndominium work for multigenerational living?
Yes, and the feature to look for is a kitchenette rather than a bedroom count. GS-8012 Florence dedicates one of its five bedrooms to a self-contained suite with its own living area, kitchenette, private bath and laundry hookups. PL-62511 Morgan’s upstairs wing does the same with a second living room. Without a kitchenette, a fifth bedroom is just a bedroom.
Do 5 bedroom barndominiums cost more per square foot?
Usually slightly, yes. Bathrooms are the most expensive rooms per square foot in any house, and five-bedroom plans carry three to four and a half of them. Bedroom count also tends to force HVAC zoning that a three-bedroom plan of the same total footage can avoid. Expect to land in the upper half of the $65 to $160 range rather than the lower.
