100×100 Metal Building
10,000 sq ft 14 to 20 ft eave
A 100×100 metal building delivers 10,000 square feet of clear span, column-free floor space under one roof, making it one of the most popular sizes for warehousing, distribution, light manufacturing and large commercial use. Universal Steel of America engineers and fabricates every 100×100 building as a pre-engineered steel structure, certified to your local snow, wind and seismic code before it ships.
As a US manufacturer founded in 1995, we design the primary frame, fabricate the red-iron steel and ship from the plant closest to your site, serving the US and internationally across the Caribbean, Puerto Rico, South America and Africa. You receive a complete, code-stamped building package. Professional erection is available as an optional service, so you can have a turnkey crew raise it or use your own contractor.

Popular uses for a 100×100 Metal Building
Warehouse and distribution
At 10,000 square feet with a 100 ft clear span, a 100x100 building is a workhorse warehouse or small distribution center. The column-free floor lets you run full racking aisles and stage inbound and outbound freight, while a 16 to 20 ft eave gives forklifts and tall pallet racks room to operate. Add dock-high or grade-level doors to match your loading flow.
Metal warehouse buildingsLight manufacturing and industrial
Manufacturers use the open 100x100 span for production lines, assembly cells and finished-goods storage in one shell. We can engineer the frame for overhead cranes, heavier collateral loads and the door openings that fit your equipment. Taller eaves and reinforced framing are specified to suit your process.
Industrial steel buildingsCold storage facility
The clear span suits insulated cold storage and refrigerated warehousing, where uninterrupted floor space and a continuous insulation envelope matter. We engineer the structure to carry the added loads of an insulated panel system and the door and dock configuration your operation needs. Finishes and R-values are matched to your temperature targets.
Cold storage buildingsIndoor riding arena
A 100 ft width gives horses a genuine working surface, and the column-free interior keeps the riding area clear from wall to wall. The 100x100 size suits a compact covered arena for training, lunging and year-round riding. We can raise the eave and add ventilation and large doors so the space rides comfortably in any season.
Riding arena buildingsGymnasium and indoor sports
Ten thousand square feet is the practical floor a full gymnasium needs, and a 100x100 clear span fits a regulation basketball court with room around the sidelines. The open frame also suits volleyball, pickleball, fitness floors and youth sports. We set the eave height for backboards, scoreboards and clearance over play.
Gymnasium buildingsLarge commercial and retail
For showrooms, trade counters, indoor markets and multi-tenant commercial space, the 100x100 shell gives you a wide, open footprint to fit out as you like. The pre-engineered frame goes up fast, so you reach occupancy sooner than with conventional construction. Storefronts, glazing and interior partitions are added to suit your build.
Commercial steel buildingsWhy 10,000 square feet works so well
The 100×100 footprint hits a sweet spot for commercial and industrial owners. A full 100 ft clear span keeps the interior free of interior columns, so you can lay out racking aisles, production lines, vehicle bays or a regulation court without working around posts. Pair that width with a 14 to 20 ft eave and you have the headroom for forklifts, mezzanines, overhead cranes and tall roll-up doors.
From warehouse to workshop to indoor arena
Because the frame is engineered to order, the same 100×100 shell adapts to very different jobs. Distribution and self-storage operators value the open floor and high eave; manufacturers add cranes and three-phase power; equestrian owners get a 100 ft wide riding surface; sports groups fit a competition gym. We size the frame, bracing and openings around the use you specify, not a one-size catalog kit.
Adding living quarters or a shop house
Some owners split a 100×100 into a workshop plus living quarters, often around 7,000 square feet of shop and 3,000 square feet of finished living space. If a home is part of your plan, that is a barndominium build. We can engineer the shell for it, and you can read more on our barndominiums page before you decide on layout and finishes.
100×100 Metal Building questions
How much does a 100x100x20 metal building cost?
Industry-typical pricing for an engineered 100x100x20 steel building shell runs roughly $8 to $14 per square foot, so about $80,000 to $140,000 for the kit alone. A finished, turnkey building usually lands around $190,000 to $400,000 once you add the concrete foundation, erection, insulation, doors and site work. The exact figure depends on your eave height, snow and wind loads and finish, so request an engineered quote for a firm price.
How big is a 100x100 building?
A 100x100 building is 100 feet wide by 100 feet long, which is exactly 10,000 square feet of floor space. With a clear span frame the entire 10,000 square feet is column-free and usable. That is large enough for a regulation basketball court, a sizable warehouse or a light manufacturing floor with room to spare.
How much does it cost to erect a 100x100 metal building?
Professional erection of a 100x100 metal building typically runs about $3 to $8 per square foot, so roughly $30,000 to $80,000 for a building this size. The cost depends heavily on your region, site access and contractor availability. Erection is an optional service, so you can hire a turnkey crew or have your own qualified contractor raise the building.
Is a steel building cheaper than a pole barn at this size?
At 10,000 square feet a pole barn can look cheaper up front, but a pre-engineered steel building usually wins on lifespan, clear span and code compliance. Steel gives you a true 100 ft column-free interior, non-combustible framing and a 25 to 40 year finish warranty on the panels. For a commercial or industrial 100x100, the engineered steel structure is typically the better long-term value.
What eave height should a 100x100 metal building have?
Most 100x100 buildings use an eave height of 14 to 20 feet. Warehouses, manufacturing and cold storage usually favor the taller end for racking, forklifts, cranes and tall doors, while a gymnasium or arena is set by the clearance needed over the playing or riding surface. We engineer the frame to the exact eave height your use requires.
