60x100 Barndominium

This page is ordered around height and clearance, because at 60x100 the 18-foot eave limits a barndominium sooner than the plan does.

The footprint holds 12 bands — 3 across by 4 deep — and leaves 16 feet of depth for a middle band holding utility, storage and circulation, which is what keeps the living and working sides from touching.

What distinguishes 60x100 is depth behaviour: 4 rows along 100 feet after 12 feet of circulation, with 16 feet unaccounted for at the end of the run. What the building holds in its busiest week is the honest brief; the rest of the year is slack.

A 60 by 100 footprint is a clearly directional plan: 6,000 sq ft enclosed by 320 ft of wall, at a 1.7:1 length-to-width proportion. Along its 100 ft dimension it takes 5 runs of bands at 18 ft, leaving 10 ft over — the 10 ft is where the argument about this size actually happens. Taken purely as arithmetic, 60 by 100 gives 3 bands across the 60 ft dimension once 12 ft is reserved for movement, and 5 deep along the 100 ft dimension. Run as a a wide plan where separation is achieved by a buffer zone rather than a single wall, 0 ft across is below the 12 ft this use needs to be worth planning, so there is no middle band, so living and working spaces share a wall and every noise and temperature difference sits on it Noise transfer, not floor area, is the usual complaint in a combined building.

At 60x100 the operating question is a specific one: is the space between the two sides doing useful work, or is it just a wall? That is a different question from the one a barndominium of another shape has to answer, and it is why this footprint is planned as a wide plan where separation is achieved by a buffer zone rather than a single wall rather than as generic covered area.

Across a 60-foot span the 3:12 pitch adds 7.5 feet between eave and ridge. The centreline measures 25.5 feet; anything parked or stacked near a wall lives with the 18-foot eave. Long spans buy flexibility that is only worth paying for if the operation actually changes shape.

Height on a 60 ft span is a separate decision from the 100 ft length, and it is the span that sets the frame's behavior. Raising the eave over 6,000 sq ft affects every bay along the 100 ft dimension, so the test is whether wide barndominium plan genuinely needs the extra clear height or only the floor area.

Ventilation across 6,000 square feet at this height: the working half generates air the living half should never receive, so the boundary handles air as well as sound.

The 60-ft span holds 3 bands plus 12 ft — most of another position. With 4 ranks behind each other the width sets retrieval order: what goes in first comes out last.

Nothing lands in the middle of a 60-ft clear width. The 4 ranks along the 100-ft length are the only fixed geometry the plan has; every other division is furniture.

100 ft divides exactly into 10 bays at 10 ft. Over 6,000 sq ft a single 10-ft grid is the difference between a plan and an accumulation.

100 ft is deep enough for 4 ranks and a zone behind them. 6,000 sq ft needs a stated route through it; without one the middle silts up.

The 12 ft left across the width is most of another band without being one. Given a purpose it becomes a middle band holding utility, storage and circulation, which is what keeps the living and working sides from touching; left undefined it becomes the strip everything ends up in.

18 ft carries a genuine second level: 18 ft deep across the 60-ft width is 1,080 sq ft more floor. The stair comes out of the 12 ft of spare width rather than out of the working floor.

The living-and-working balance this footprint could equally be planned around is a dwelling with a working bay attached rather than a shop with rooms in it: there is no buffer between the working bay and the living rooms, so the shop door opens straight into occupied space. Three bands across or along the plan: occupied, buffer, working. The buffer earns its area by carrying everything neither side wants to house.

Depth arithmetic leaves a working end zone here. 960 square feet sits past the last row, which is why 60x100 tends to be planned with a middle band holding utility, storage and circulation, which is what keeps the living and working sides from touching designed in rather than added later. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.

Spare width is the more valuable of the two leftovers here: a continuous 12-foot strip beats the same area stranded at the end of the run, because it touches every position along the way. Interior divisions are the last decision that should be fixed, because they are the first one that usually changes.

Spent as a square 77 by 77 instead, the same 6,000 sq ft would stand 4 bands across rather than 3, and would trade this plan's length for parallel access. That is the width-against-depth decision this footprint has already made. Compared with a 60 by 80 of the same width, the extra depth here adds run rather than reach: it buys about 5 bands in line, and every position past the second is retrieved by moving what stands in front of it. At this size the building becomes a shared resource, and shared resources need a written rule for who parks where and which door is kept clear. The two routines never share a route. The buffer takes the crossings, which is why the laundry, the boot room and the plant tend to end up there. Noise transfer, not floor area, is the usual complaint in a combined building. That movement pattern, not the 6,000-square-foot total, is what decides whether the leftover 16 feet is useful here.

The 60-foot gable can carry 3 openings, one per band, with 12 feet of wall left for piers between and beside them — the arrangement that keeps each position independently reachable. Depth is bought cheaply and width expensively, which is why this proportion tends to be argued about before anything else.

The 60 ft ends and the 100 ft sides offer very different opening budgets: 60 ft of end wall has room for one wide opening or two modest ones, while 100 ft of side wall can carry several without the openings competing. On this plan the deciding factor is whether wide barndominium plan or buffer band between living and shop should be the first thing reached from the door.

At 25-foot nominal bays the structure works with the layout instead of against it: one band per bay line, walls free of awkward half-positions. Utilities entering on the wrong elevation quietly rewrite the interior layout.

With 4 rows deep, the rear row is behind the front one. Without a route past it, those bands become storage positions rather than working ones — the real cost of depth at this width. Insulating later is possible; framing for insulation later is much harder.

Both outer bands can grow independently once the buffer exists, which is what makes this the most tolerant of the barndominium arrangements.

Configured as a wide plan where separation is achieved by a buffer zone rather than a single wall, 60x100 is judged on whether the 12 bands it holds match the operation, and on whether the 12 feet of spare width leaves the route this mode depends on.

• Does the work need four lanes across, or two lanes flanking an interior work hall, or does it need a second lane that this 60-foot span cannot give?
• Is the 100-foot length being bought for depth, or for the repeated bays — eight to ten repeated bays, which makes the layout a scheduling problem as much as a spatial one?
• Where does the dividing wall sit, and what does the working half lose when it moves?
• Is there a loft, and has the frame been planned for it rather than around it?

• 30x80 moves the count from 12 to 6 bands (2 across by 3 deep), which is the reason to choose between them.
• 40x60 moves the count from 12 to 6 bands (3 across by 2 deep), which is the reason to choose between them.
• 50x50 moves the count from 12 to 6 bands (3 across by 2 deep), which is the reason to choose between them.

Because this footprint is planned as a wide plan where separation is achieved by a buffer zone rather than a single wall, the useful next reads are different from the ones a differently shaped barndominium suggests: wide barndominium plan, buffer band between living and shop, three-band layout.

No price appears on this page. The quantities that scale an estimate at 60x100 are 6,000 square feet of slab, 111.1 cubic yards of nominal concrete, 5,760 square feet of wall cladding and 6,185 square feet of roof cladding. Height is the dimension people regret; it cannot be added later without rebuilding the frame line.

The buffer band is floor area that is not living space and not shop, so the honest question is whether the plan is large enough to afford it. Below a certain width it is not.

• the envelope and separation detail between the two halves
