An L-shaped barndominium is two wings meeting at a right angle instead of one long rectangle. That single change does three things at once: it separates the living space from the working space, it shortens the building so it fits a lot a 120-foot rectangle would not, and it turns the inside corner into a sheltered courtyard that a straight barndominium has no way to produce.
The four L-shaped floor plans below run from 1,500 to 5,583 heated square feet. What they have in common is not size — it is how much of each building is not house. Every one of them carries a garage or shop wing between 600 and 3,522 square feet, and on two of the four that unheated space is more than half of everything under roof. That is the honest reason these plans are L-shaped rather than rectangular: the second leg has a job.
Every figure below is taken from the plan’s own specification sheet. Where a published number does not reconcile, it says so and tells you what to confirm before you buy.
Featured L-Shaped House Plans With Garages
GJ-4406 Jefferson
5,583 sq ft heated · 8,940 sq ft under roof · 2,107 sq ft garage · 1,250 sq ft covered porch · 2 bed · 3.1 bath · 120′ x 90′
The Jefferson is the largest plan here and the most unusual: 5,583 heated square feet arranged around only two bedrooms. That ratio tells you what it is for. This is not a plan for a big family — it is a plan for people who want the space in the living areas rather than in bedroom count, with three full baths and a half bath serving them. Ceilings are ten feet across the whole first floor, and all 5,583 square feet sit on that one level.
The footprint is 120 feet wide by 90 feet deep, which is the number to check first. That is a large piece of ground before setbacks, and it is the single thing most likely to rule this plan out. Against that outline, 8,940 square feet sits under roof — well short of what a full 120 by 90 rectangle would cover, which is what the L is doing for you. The 2,107 square foot garage and 1,250 square feet of covered porch account for the difference between the heated area and the total. Metal shell on a 5:12 roof, 22 feet to the ridge. From $1,749.99.
LP-2803 Wickard
4,385 sq ft heated · 9,407 sq ft under roof · 3,522 sq ft garage, 4 cars · 3 bed · 2.2 bath · 50′ x 100′ · 2 stories with a loft
The Wickard is the plan on this page where the working space genuinely rivals the house. Its garage runs 3,522 square feet across four bays — split into separate garages, one of them with its own half bath — against 4,385 square feet of heated living space. Put another way, less than half of the 9,407 square feet under roof is house. If you are looking at L-shaped plans because you need a serious shop and not just parking, this is the one to open first.
The living side is single-level: all 4,385 heated square feet are on the first floor, with three bedrooms, two full baths and two half baths, ten-foot ceilings, a mudroom, an outdoor fireplace and a covered balcony. The second story is a loft rather than an enclosed floor, which is why the heated total does not split across levels.
One figure to raise with the designer before you buy. The published dimensions are 50 feet by 100 feet, which encloses 5,000 square feet — but the plan lists 9,407 square feet under roof, and the heated area alone is 4,385. Those numbers cannot describe the same outline, so the 50 by 100 is almost certainly the house rather than the whole building, with the garages sitting outside it. Confirm the overall footprint before you commit to a lot, because it matters for setbacks. Metal shell, concrete slab, 6:12 roof. From $1,499.99.
BCO-40176 Spencer
1,800 sq ft heated · 4,117 sq ft under roof · 1,400 sq ft garage · 584 sq ft porch · 3 bed · 2 bath · 86′ x 68′ · 1.5 stories
The Spencer is the most conventional household on this page — three bedrooms, two full baths, 1,800 heated square feet — attached to a 1,400 square foot garage that is nearly as large as the house. Of the 4,117 square feet under roof, fewer than half are heated. For a three-bedroom family that also needs real covered workspace, that balance is hard to find in a rectangular plan without either shrinking the house or building something enormous.
It is also the only stick-framed plan in this lineup rather than a metal shell, and the only one with a steep roof at 10:12 — which is where the half story comes from. Nine-foot ceilings on the first floor, a 584 square foot wraparound porch, and a loft above. The outline is 86 by 68 feet; a full rectangle at those dimensions would cover 5,848 square feet against the 4,117 actually under roof, so the L is buying you a shorter building on both axes than the heated space alone would suggest. From $849.99.
CDD-4104 Beechwood
1,500 sq ft heated · 2,400 sq ft under roof · 600 sq ft garage · 2 bed · 2 bath · 60′ x 30′ · 1 story
The Beechwood is the smallest and the cheapest to build here, and the only one that would sit comfortably on an ordinary residential lot rather than acreage. Two bedrooms, two full baths, 1,500 heated square feet, a 600 square foot garage, nine-foot ceilings and a 6:12 roof on a concrete slab. Total under roof is 2,400 square feet, so the proportions are closer to a conventional house than anything else on this page — the garage is a garage, not a shop.
Check the dimensions against the areas before you plan a site. The published outline is 60 feet by 30 feet, which encloses 1,800 square feet, and the plan lists 2,400 square feet under roof. The garage cannot be inside that outline, so the 60 by 30 describes part of the building rather than all of it. Ask the designer for the overall dimensions before you buy, particularly if you are fitting this to a narrow lot. From $849.99.
Why Build An L-Shaped Barndominium
A rectangular barndominium is cheaper per square foot and simpler to frame. The L costs more to build, so it has to earn that back somewhere. It usually earns it in four places.
The Working Space Stops Sharing A Wall With The Bedrooms
In a straight barndominium the shop and the living space sit end to end along one axis, which means noise, dust and vehicle exhaust travel down the length of the building. Turning the shop into its own wing puts a corner between it and the bedrooms. It is the same reason a dogtrot works, achieved without giving up the connection between the two.
The Building Gets Shorter
Length is what makes barndominiums hard to site. A plan carrying 4,000 square feet of house and shop in one line can run 150 feet or more, which needs frontage most lots do not have. Fold it into an L and the same area fits inside a much squarer outline — the Spencer carries 4,117 square feet under roof inside an 86 by 68 foot envelope.
The Inside Corner Becomes A Courtyard
This is the reason most people end up choosing the shape, and it is the one a floor plan drawing understates. The angle creates a courtyard sheltered on two sides. It blocks wind from two directions, it sits out of sight of the road, and it is the natural place for a patio, an outdoor kitchen, a fire pit or a pool. A rectangular building cannot produce this space at all — every side faces out, so any outdoor area you create is exposed on three sides.
It also changes how the house is entered. With the front door set into the inside corner rather than along a flat elevation, arrivals happen in a protected space rather than on an open wall, which is why this layout is often called a courtyard entry. If the outdoor room matters more to you than the shop does, that is the detail to look at first on each floor plan: whether the corner is left open to be lived in, or already filled by the porch.
Two Wings Can Be Built In Two Stages
The joint between the wings is a natural place to stop. Some owners build the shop wing first, work out of it while the house wing goes up, and finish in two phases. Discuss it with your builder before you start, because the foundation and the roof connection have to be designed for it from the beginning.
L-Shaped Ranch House Plans
Most L-shaped barndominiums are ranch homes in the literal sense: everything on one level, spread horizontally rather than stacked. Three of the four plans here put all of their heated space on the first floor, and two of them — the Jefferson and the Beechwood — are single story throughout.
That combination is worth understanding as a choice rather than a coincidence. A single-story L trades vertical efficiency for horizontal reach: you pay for more foundation and more roof than a two-story house of the same area, and in return you get no stairs, a shorter run from the primary suite to the kitchen, and the ability to put windows on both sides of every room. On a rural lot where land is the cheap input and a second story is the expensive one, that trade usually favors the ranch form. On a tight lot it does not.
The Spencer and the Wickard both add a loft rather than a full second story, which keeps the single-level living pattern while using the roof volume the shape already creates.
The Disadvantages Of An L-Shaped Barndominium
Most pages selling L-shaped plans do not mention what the shape costs. It costs real money, every month, for as long as you own the building.
More exterior wall per square foot. A square encloses more area per foot of wall than any other rectangle, and every step away from square adds wall. An L is two rectangles with a shared corner, so it carries noticeably more exterior wall than a straight building of the same area — more framing, more insulation, more siding, and more surface losing heat in January and gaining it in July. This is the disadvantage that never goes away.
Longer mechanical runs. Plumbing and ductwork have to travel around the corner rather than straight down the building. Expect longer runs, more of them, and a heating and cooling system working across two directions instead of one. Ask your HVAC contractor to look at the plan before you finalize it — a single system sized for a rectangle can struggle in an L.
It needs a wider lot than the square footage suggests. An L occupies ground in two directions at once. The Jefferson’s 120 by 90 foot outline is a bigger site requirement than its 5,583 heated square feet implies, and setbacks apply to the outline, not to the heated area.
Framing is more complex. Simple rectangular metal buildings are the cheapest thing to put up, and much of the barndominium cost advantage comes from that simplicity. Two wings, a valley and a corner give back part of it. Budget for a higher shell cost per square foot than a straight building of the same size.
What Does It Cost To Build An L-Shaped Barndominium?
A finished barndominium generally runs $65 to $160 per square foot. On the plans here that puts the Beechwood’s 1,500 heated square feet at roughly $98,000 to $240,000 and the Jefferson’s 5,583 at roughly $363,000 to $893,000, before land, site preparation, well, septic and utility connections.
Two adjustments matter more on an L than on a rectangle.
Heated square footage understates the job on these plans. Every plan here carries substantial unheated space — 2,317 square feet on the Spencer, 5,022 on the Wickard. Garage and porch cost far less per square foot than finished living space, because there is no insulation, drywall, HVAC or interior finish. But they still need slab, framing, roof structure and roofing. Price the shell against everything under roof and the interior finish against the heated area only.
The shape adds to the shell. Kit shells run about $20 to $35 per square foot with another $10 to $15 per square foot to assemble, and those figures assume a simple rectangular building. Two wings, a roof valley and a corner sit at the upper end of that band rather than the lower.
Get county-level bids before you set a budget. Labor rates and permit requirements move these numbers more than the plan does.
Which L-Shaped Plan Fits Your Build?
If the shop is the point, the Wickard is the only plan here where the working space genuinely competes with the house — 3,522 square feet across four bays, one with its own half bath. The Spencer’s 1,400 square feet is a generous garage rather than a shop. If the shop matters more than the shape does, compare these against the barndominium plans with a shop, where the workspace leads the plan rather than the layout.
If the lot is the constraint, start with the Beechwood. It is the only plan here that does not assume acreage. The Jefferson needs a site well over 120 feet across before setbacks, and the Wickard’s real outline is larger than its published dimensions.
If you want an L-shaped house plan with 3 bedrooms, that is the Spencer or the Wickard. The Jefferson puts 5,583 square feet behind two bedrooms and the Beechwood has two.
If you want the wings fully separated rather than joined at a corner, the L is not the strongest shape for it. An H-shaped barndominium gives you two wings linked by a central section, and a barndominium with a breezeway separates them completely with an open pass-through between.
If none of these four is quite right, most people find a stock plan within one modification of what they want. Changes past that point are worth pricing against a custom barndominium plan before you commit either way.
Frequently Asked Questions About L-Shape Homes
What Is An L-Shaped Barndominium?
An L-shaped barndominium is a metal or post-frame home built as two wings meeting at a right angle rather than as a single rectangle. One wing usually holds the living space and the other holds the garage or shop, and the inside corner forms a sheltered outdoor area. The shape is chosen for three reasons: it separates working space from sleeping space, it fits a shorter and squarer lot than a straight building of the same size, and it creates protected outdoor space a rectangle cannot.
What Are The Disadvantages Of An L-Shaped Barndominium?
Four, and they are worth knowing before you buy. The shape carries more exterior wall per square foot than a rectangle, which means higher framing and insulation costs and permanently higher heating and cooling bills. The inside corner creates a roof valley, which is the most common place for a metal roof to leak. Plumbing and ductwork runs are longer because they travel around a corner. And the building occupies ground in two directions, so it needs a wider site than its square footage suggests.
Does An L-Shaped Barndominium Cost More To Build Than A Rectangular One?
Yes, per square foot. A simple rectangular metal building is the cheapest shell to put up, and much of the barndominium cost advantage comes from that simplicity. Two wings, a roof valley and a corner give part of it back — expect to sit at the upper end of the $20 to $35 per square foot kit range rather than the lower. Finished, both shapes fall in the same $65 to $160 per square foot band, but an L will land higher in it than a rectangle of the same size.
How Much Land Does An L-Shaped Barndominium Need?
More than the heated square footage implies, because setbacks apply to the outline rather than to the living space. The plans here range from a 60 by 30 foot outline on the Beechwood to 120 by 90 feet on the Jefferson. Check the overall dimensions against your lot and your local setbacks before you buy any plan, and confirm the figures with the designer where a plan’s published dimensions do not enclose its full area under roof.
Can The Garage Wing Be Used As A Shop?
On most of these plans, yes — that is what the second wing is for. The Wickard carries 3,522 square feet across four separate garages, one with its own half bath, which is shop space rather than parking. The Spencer’s 1,400 square feet works as a generous workshop. The Beechwood’s 600 square feet is a garage. If you need commercial-grade ceiling height or overhead door widths, confirm those with the designer, since they are not always listed.
Can These Plans Be Modified?
Yes. Minor modifications typically cover up to three changes that do not alter the building’s overall dimensions or room sizes, and major modifications cover up to five changes or anything that does change room sizes or the footprint. You can also flip the plan, change the foundation type, add radiant floor heat or add a materials list. Pricing varies by plan series and is shown alongside each option on the plan’s own page.
