Doors & Access Considerations
Opening width
Across a 24 ft gable end, the practical opening width is limited by the frame and confirmed with the supplier.
Opening height
A 12 ft eave sets the ceiling on door height before any frame change.
Drive-through
Matching openings at both ends avoid reversing, at the cost of usable wall.
Use
How a 24×36 Detached Metal Garage May Be Used
Vehicle parking
Bay width and door placement determine how many vehicles park comfortably and how they circulate.
Workbench and tools
A wall of bench space is commonly kept clear of door swings and vehicle doors.
Household storage
Shelving depth along a side wall reduces the usable parking width, so it is planned early.
Hobby projects
Owners often reserve one bay for a project vehicle or equipment rather than daily parking.
Planning
Footprint & Space Planning
Footprint
Width and length are chosen together: width is usually fixed by what has to fit side by side, length by how many bays are needed.
Height
Eave height affects door options, storage height and how open the interior feels.
Access
Where vehicles and people enter changes the whole interior layout, so access is settled before anything else.
Doors and openings
Opening width, height and position are specified with the supplier; they affect the frame and the wall bracing.
Site
Slope, drainage, access for delivery and erection, and the foundation are confirmed for the actual property.
Expansion
Extending along the length is usually simpler than changing the width later, which is worth deciding up front.

Overview
A 24x36 detached metal garage planned as parking that shares the slab with a dedicated hobby or craft corner
This page is ordered around corner, because that is the decision this footprint settles first and every later choice follows from it.
The footprint holds 2 hobby stations — 2 across by 1 deep — and leaves 10 feet of depth for a fixed table or counter in the corner farthest from the vehicle path, left set up between sessions rather than cleared away.
Efficiency is the useful number here: 432 square feet of enclosed floor per hobby station, against a 242-square-foot module. That is generous — the footprint is doing more than hold modules. The corner nobody plans for is the one that fills first, which is an argument for planning it.
A 24 by 36 footprint is a clearly directional plan: 864 sq ft enclosed by 120 ft of wall, at a 1.5:1 length-to-width proportion. Along its 36 ft dimension it takes 1 run of hobby stations at 22 ft, leaving 14 ft over — the 14 ft is where the argument about this size actually happens. Taken purely as arithmetic, 24 by 36 gives 1 hobby stations across the 24 ft dimension once 4 ft is reserved for movement, and 1 deep along the 36 ft dimension. Run as a parking that shares the slab with a dedicated hobby or craft corner, 9 ft across is enough to be worth planning: a fixed table or counter in the corner farthest from the vehicle path, left set up between sessions rather than cleared away Whether a residential garage is attached or detached, and what separation from the dwelling that requires, is determined by the authority having jurisdiction for the specific lot.
This footprint is planned as parking that shares the slab with a dedicated hobby or craft corner. Spent as a square 29 by 29 instead, the same 864 sq ft would stand 2 hobby stations across rather than 1, 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 24 by 30 of the same width, the extra depth here adds run rather than reach: it buys about 1 hobby stations in line, and every position past the second is retrieved by moving what stands in front of it. At this scale the building is usually operated by one or two people who know where everything is, so the plan can be loose and the doors matter more than the divisions. Two different rhythms share the slab: parking daily, the hobby in short unpredictable bursts. The hobby loses that contest unless its footprint is protected from being treated as leftover space. Fueled equipment and paper, fabric or cardboard storage are best kept in separate zones within the same building.
Areas, perimeter, roof area, ridge height, slab volume and the hobby station counts on this page are computed from the stored 24x36 record and this platform's planning module for the detached metal garage category.
Configurations
Configuring 2 hobby stations at 24x36
Nominal bay division computes to 2 bays at about 18 feet, wider than the 11-foot module — so a position can sit inside a bay without a frame line splitting it. Interior divisions are the last decision that should be fixed, because they are the first one that usually changes.
One row deep keeps the layout honest — no aisle to protect, no rear zone to serve, and the full 36-foot length available along the wall. Utilities entering on the wrong elevation quietly rewrite the interior layout.
Extension is cheapest along the 36 ft dimension, where each added bay repeats work already framed; widening past 24 ft is a different frame rather than a longer one. Growing to 24 by 58 adds a 2th run of hobby stations — useful if the constraint is hobby stations rather than the 14 ft already spare at the far end.
Configured as parking that shares the slab with a dedicated hobby or craft corner, 24x36 is judged on whether the 2 hobby stations it holds match the operation, and on whether the 2 feet of spare width leaves the route this mode depends on.
- Does the work need one generous vehicle lane plus a walking route that does not brush the sidewall, or does it need a second lane that this 24-foot span cannot give?
- Is the 36-foot length being bought for depth, or for the repeated bays — two or three divisions, enough grain to place a partition but not to dedicate a bay?
- Where does the walk door face, and does that match the path from the house?
- Is a storage loft wanted, and has the frame been planned for it?
Bay division shown here is a planning module computed from the stored length. Actual bay spacing is set by the manufacturer's frame design for the building.
Openings
Openings for 2 hobby stations across
Openings are the pinch point here. With 2 feet of spare width the gable cannot host 2 separate doors, so access is either shared or moved to the 36-foot sidewall. Long spans buy flexibility that is only worth paying for if the operation actually changes shape.
The 24 ft ends and the 36 ft sides offer very different opening budgets: 24 ft of end wall has room for one wide opening or two modest ones, while 36 ft of side wall can carry several without the openings competing. On this plan the deciding factor is whether garage hobby corner or craft space with parking should be the first thing reached from the door.
Framed-opening sizes, headers and the structure around them are engineered for the specific building. Confirm every opening with the door supplier and the building manufacturer before ordering.

Height
Interior height for a 24x36 detached metal garage
Span drives headroom at 24x36: 24 feet of width on a 4:12 pitch puts 16 feet over the middle and 12 feet at the walls, so where a tall item stands matters as much as how tall it is. Insulating later is possible; framing for insulation later is much harder.
Pegboard and shallow shelving above the hobby table extend its usable surface without touching the floor the vehicle needs.
A detached building is heated only when used, so insulation is judged against how long a visit lasts.
Clear height below purlins, bracing and lighting is lower than the eave height. The usable figure comes from the manufacturer's framing for the selected building.
Allocation
Dividing the floor for parking that shares the slab with a dedicated hobby or craft corner
The role this building could equally play beside the house is a fixed workshop bay standing beside — not instead of — the parking: the bench has no permanent footprint, so it is folded away or covered every time the bay is needed for the vehicle. The vehicle claims a defined lane, and the hobby corner claims a fixed footprint diagonal from the door swing, so neither has to be renegotiated when the other is in use.
Because 10 feet clears the 6 feet this platform treats as usable, the end of the run is a room rather than a gap: 240 square feet for a fixed table or counter in the corner farthest from the vehicle path, left set up between sessions rather than cleared away. What the building holds in its busiest week is the honest brief; the rest of the year is slack.
Width is fully committed at 24x36. With 2 feet spare, wall storage and passing room compete with the hobby stations directly. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.
Spent as a square 29 by 29 instead, the same 864 sq ft would stand 2 hobby stations across rather than 1, 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 24 by 30 of the same width, the extra depth here adds run rather than reach: it buys about 1 hobby stations in line, and every position past the second is retrieved by moving what stands in front of it. At this scale the building is usually operated by one or two people who know where everything is, so the plan can be loose and the doors matter more than the divisions. Two different rhythms share the slab: parking daily, the hobby in short unpredictable bursts. The hobby loses that contest unless its footprint is protected from being treated as leftover space. Fueled equipment and paper, fabric or cardboard storage are best kept in separate zones within the same building. That movement pattern, not the 864-square-foot total, is what decides whether the leftover 10 feet is useful here.

FAQ
Questions about 24x36 detached metal garage projects
A 4-inch slab across 864 square feet computes to 10.7 cubic yards before thickened edges, piers or waste. The final design comes from the foundation engineer.
Reserving 4 ft across the 24 ft dimension for movement leaves 20 ft of working width, which takes 1 hobby stations at 11 ft. Along 36 ft it takes 1 runs at 22 ft. That is 1 positions out of 864 sq ft, and the remainder is circulation, walls and the margin every plan needs. Whether that count is enough depends on does the hobby corner survive the vehicle being parked, or is it packed up and reassembled every time someone wants to use it. These are planning figures computed from the footprint, not a quoted layout.
1,440 square feet of wall and 911 square feet of roof at a 4:12 pitch — the roof exceeding the floor by 5%.
A dedicated circuit is worth planning for tools, lighting or a kiln-type appliance, since sharing a circuit with the vehicle door opener invites tripped breakers at the worst moment.
The width leaves 2 feet spare after 2 hobby stations. That margin absorbs wall storage and passing room. Width is the dimension that cannot be extended later.

Cost drivers
Quantities that move the estimate at 24x36
The estimate at 24x36 moves with four computed quantities: 864 square feet of floor, 120 feet of perimeter, 1,440 square feet of wall and 911 square feet of roof. Everything else is site and specification. Depth is bought cheaply and width expensively, which is why this proportion tends to be argued about before anything else.
A dedicated circuit and adequate lighting at the hobby station are the items worth budgeting deliberately; without them the corner is used less than its footprint would suggest.
- the driveway extension and apron to a separate structure
- running services to a detached building
- matching the house elevation and roofline
- a storage loft over the parking area
