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.
Use
How a 100×100 Indoor Sports Facility May Be Used
Courts
Clear-span width determines how the main space can be arranged and seated.
Training
Ancillary rooms are commonly placed along one side or at one end.
Recreation
Entrance and exit placement follows the occupancy requirements for the use.

Doors & Access Considerations
Opening width
Across a 100 ft gable end, the practical opening width is limited by the frame and confirmed with the supplier.
Opening height
A 22 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.

Overview
A 100x100 indoor sports facility planned as a floor planned to divide between simultaneous groups
This page is ordered around programming, because at this footprint the question is not how much floor there is but how many groups it can hold at once and how each of them reaches its zone.
The footprint holds 2 divided zones — 2 across by 1 deep — and leaves 26 feet of depth for a cross-circulation strip so each divided zone is reached without crossing the others.
What distinguishes 100x100 is depth behaviour: 1 row along 100 feet after 14 feet of circulation, with 26 feet unaccounted for at the end of the run. The plan is only as good as the route into it, which is a site question rather than a building one.
A 100 by 100 footprint is a near-square plan: 10,000 sq ft enclosed by 400 ft of wall, at a 1:1 length-to-width proportion. Along its 100 ft dimension it takes 1 run of divided zones at 60 ft, leaving 40 ft over — the 40 ft is where the argument about this size actually happens. Division is what turns a floor into a schedule. The planning question is not whether the area can be split but whether each split zone can be entered, supervised and used without affecting the others — and that is a circulation problem rather than an area one. Parking and drop-off govern peak arrival more than the entrance does, and they are settled at site stage.
This footprint is planned as a floor planned to divide between simultaneous groups. At 1:1 the plan is close enough to square that neither width nor depth is doing the arguing; what decides the layout here is where the openings go, because no proportion is forcing a direction on the floor. Spent as a square 100 by 100 instead, the same 10,000 sq ft would stand 1 divided zones 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. A building of this size behaves like a small yard under a roof: zones need to be defined, signed and left alone, or they migrate. The longest internal travel on a 100 by 100 plan is about 141 ft corner to corner, and the shortest useful one is the 100 ft cross-run. For a a floor planned to divide between simultaneous groups that matters where divided activity zones sits, because shortening the 100 ft run to serve it lengthens every trip along the 100 ft dimension. Supervision sightlines from a single position are worth more to daily operation than most interior finishes.
Areas, perimeter, roof area, ridge height, slab volume and the divided zone counts on this page are computed from the stored 100x100 record and this platform's planning module for the indoor sports facility category.
Configurations
Configuring 2 divided zones at 100x100
The columns win at this footprint: 25-foot nominal bays against a 45-foot module means every layout decision starts from where the frames fall. Security and after-hours access are easier to design in the door layout than to bolt on later.
One row deep keeps the layout honest — no aisle to protect, no rear zone to serve, and the full 100-foot length available along the wall. The span is the commitment; everything inside it is rearrangeable later, and the 100-foot dimension is not.
Extension is cheapest along the 100 ft dimension, where each added bay repeats work already framed; widening past 100 ft is a different frame rather than a longer one. Growing to 100 by 160 adds a 2th run of divided zones — useful if the constraint is divided zones rather than the 40 ft already spare at the far end.
Configured as a floor planned to divide between simultaneous groups, 100x100 is judged on whether the 2 divided zones it holds match the operation, and on whether the 10 feet of spare width leaves the route this mode depends on.
- Does the work need an interior street with independent zones on both sides and turning room at each end, or does it need a second lane that this 100-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?
- Which sport sets the clear height, and does every zone meet it?
- How does the floor subdivide, and does the structure allow the dividing lines you want?
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.
Allocation
Dividing the floor for a floor planned to divide between simultaneous groups
The programming pattern this floor could equally be scheduled as is a single activity floor scheduled for one group at a time: the margin is minimal, so equipment and waiting participants stand at the edge of the active surface. Divide across the short dimension so each zone keeps a usable proportion, and reserve a circulation strip along one side that reaches every zone. Dividing along the long dimension produces zones nobody can enter without walking through activity.
Because 26 feet clears the 12 feet this platform treats as usable, the end of the run is a room rather than a gap: 2,600 square feet for a cross-circulation strip so each divided zone is reached without crossing the others. Whoever operates the building daily should read the plan before it is frozen, because they know where the pinch points are.
The 10 feet of spare width runs the whole 100-foot length — 1,000 square feet of wall strip. It earns its keep as shelving, staging or a walking route, not as another divided zone. Daylight placement changes how a floor is used far more than its cost suggests.
At 1:1 the plan is close enough to square that neither width nor depth is doing the arguing; what decides the layout here is where the openings go, because no proportion is forcing a direction on the floor. Spent as a square 100 by 100 instead, the same 10,000 sq ft would stand 1 divided zones 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. A building of this size behaves like a small yard under a roof: zones need to be defined, signed and left alone, or they migrate. The longest internal travel on a 100 by 100 plan is about 141 ft corner to corner, and the shortest useful one is the 100 ft cross-run. For a a floor planned to divide between simultaneous groups that matters where divided activity zones sits, because shortening the 100 ft run to serve it lengthens every trip along the 100 ft dimension. Supervision sightlines from a single position are worth more to daily operation than most interior finishes. That movement pattern, not the 10,000-square-foot total, is what decides whether the leftover 26 feet is useful here.

Openings
Openings for 2 divided zones across
One opening per position works on this gable: 2 across 100 feet, with 10 feet of wall to distribute as piers. Splitting that margin evenly is what keeps the elevation buildable. The building is fixed for decades while the operation inside it changes every few years, and the plan has to survive that.
The 100 ft ends and the 100 ft sides offer very different opening budgets: 100 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 divided activity zones or simultaneous programming 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 100x100 indoor sports facility
The stored configuration carries a 22-foot eave and computes to 38.7 feet at the ridge on a 4:12 pitch — a 16.7-foot rise across 100 feet. Height is therefore not uniform, and the sidewall is the constraint. Doors and their approaches decide more about daily use here than the enclosed area does.
Height applies across the whole floor even where only one zone needs it, which is one of the costs of a divided plan. Any dividing curtains or systems are specified for the specific building.
Ventilation across 10,000 square feet at this height: sustained high activity across a large volume, so air handling is sized for the busiest scheduled period.
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.

Areas are arithmetic on two stored size records; divided zone counts use this platform's 45 by 60 foot planning module and are not a capacity statement.
Because this footprint is planned as a floor planned to divide between simultaneous groups, the useful next reads are different from the ones a differently shaped indoor sports facility suggests: divided activity zones, simultaneous programming, independent zone access.

FAQ
Questions about 100x100 indoor sports facility projects
About 2,600 square feet across the width — enough for a cross-circulation strip so each divided zone is reached without crossing the others.
Reserving 14 ft across the 100 ft dimension for movement leaves 86 ft of working width, which takes 1 divided zones at 45 ft. Along 100 ft it takes 1 runs at 60 ft. That is 1 positions out of 10,000 sq ft, and the remainder is circulation, walls and the margin every plan needs. Whether that count is enough depends on can the floor be divided into simultaneous zones that are independently reachable, or only into zones that share an entrance. These are planning figures computed from the footprint, not a quoted layout.
It depends on the highest ball flight or activity envelope of the most demanding sport booked. The stored configuration computes to 38.7 feet at the ridge, but the eave is the number that governs anything standing near a wall.
Independent access to each zone and support capacity sized for simultaneous groups. Without both, division produces zones that can be booked but not used at the same time.
The footprint holds 2 divided zones — 2 across by 1 deep — and leaves 26 feet of depth for a cross-circulation strip so each divided zone is reached without crossing the others. Those counts use a 45 by 60 foot planning module with 14 feet allowed for circulation, so a different module changes the answer.

Cost drivers
Quantities that move the estimate at 100x100
The estimate at 100x100 moves with four computed quantities: 10,000 square feet of floor, 400 feet of perimeter, 8,800 square feet of wall and 10,541 square feet of roof. Everything else is site and specification. The floor treatment is a use decision that outlasts most of the equipment standing on it.
Proportion drives cost here as much as size does: 400 ft of wall around 10,000 sq ft is 0.04 ft of wall per enclosed square foot, and a squarer plan of the same area would carry less. What moves the figure further on a a floor planned to divide between simultaneous groups is the fit-out divided activity zones implies, along with framed openings and the height chosen for the 100 ft span.
- clear height set by the most demanding activity
- the clear span and how the floor subdivides
- zoned lighting and control
- equipment storage rooms opening onto the floor
