Best-Rated Pole Barn Builders in St. Marys, KS | Expert Post-Frame Construction for Machine Sheds, Shops & Hay Barns
Combines, grain carts and header trailers set the size of every machine shed we build as St. Marys Expert Pole Barn Builders, and Topeka Expert Pole Barn Builders also puts up shops and hay barns on nearby acreages. We size the doors to your widest machine and set every column on a poured footing.
We measure your equipment before we draw a truss. Our crew pulls the city or county permit, calls 811, augers the holes and sends a free written estimate. We've built metal buildings as large as 80,000 square feet, so even the widest machine shed around St. Marys is planned by people who have framed bigger.

We Build Pole Barns and Post-Frame Buildings in St. Marys, KS
Most of our St. Marys calls come from farm operations that have outgrown an old shed. A combine, a grain cart, a planter and a header on its trailer need floor space and a door wider than older buildings ever had. We design around the machines, then handle the permit with the City of St. Marys or the county, depending on where the parcel sits.

What We Measure Before Drawing a St. Marys Machine Shed
We take these measurements on your yard, not from a brochure.
- Widest machine through the door. We measure the combine with its head off, the grain cart and the planter folded, then add working clearance on each side.
- Tallest point. Cab, grain tank extensions and folded augers set the door height and the side wall height.
- Header trailer length. A head on its trailer needs a long straight run, so we plan the bay depth and door location around it.
- Turning room on the yard. We check the apron and approach so you can swing the combine square to the door.
Why the Wichita 14/42/60 Rule Has No Bearing in St. Marys
Farmers around St. Marys sometimes hear that a shed over 14 ft walls, 42 ft wide or 60 ft long needs a stamped engineer. We explain that rule belongs to Wichita and Sedgwick County. Kansas law exempts farm buildings from licensed design, though we still build every shed to engineered truss drawings.
"Any machine shed over 14 ft walls, 42 ft wide or 60 ft long needs an engineer's stamp."
"We follow Kansas law, which exempts farm buildings, and we still bring in a Kansas-licensed engineer on large clear spans or when an office asks for sealed drawings."
How We Frame Wide Door Openings for St. Marys Combines
A big door in a post-frame wall means a missing column, so we carry the roof over the opening on an engineered header and set heavier laminated columns on each side. Endwall doors can rise into the gable for extra height. Sidewall doors on long sheds need the truss layout planned around them from the start.
We hang sliding doors where budget matters most, bi-fold or hydraulic doors where wind and daily use make a sealed, quick door worth it. We set the door on its own footing plan and brace the frame for the wind load it catches when open, a load our engineer sets for your site.
What We Ask St. Marys Farmers to Gather
Have these ready and we can price your shed on the first visit.
- Machine list - Make and model of each piece you plan to store, including the next combine you expect.
- Parcel details - We confirm whether the city or a county reviews it, and on river-bottom ground we check the flood map first.
- Door preferences - Sliding, bi-fold or hydraulic, and which wall faces the yard.
- Power plans - Where shop lights, outlets and heat will go.

Old St. Marys Equipment Sheds Next to What We Build Now
We replace a lot of older sheds around St. Marys, and these are the usual differences.
| What it is | The usual approach | How we do it |
|---|---|---|
| Door width | Sized for a smaller combine generations ago | Measured to your current machines plus clearance |
| Side walls | Short walls that block a cab or auger | Taller walls set by your tallest machine |
| Posts | Untreated or shallow posts | UC4B treated or laminated columns on poured footings at 36 in. |
| Floor | Dirt that ruts and holds water | Compacted gravel or a slab, set above surrounding grade |
What Moves the Price of a St. Marys Machine Shed
We price a machine shed from the drawings up. Span, wall height and the size of the big door set most of the cost, because they drive truss depth, column size and header design. Floors, insulation and lean-tos come next. Our free written estimate shows each part on its own line.
Clear span
Going from 60 to 80 ft deepens the trusses and adds laminated columns.
Big door type
Sliding doors cost less than bi-fold or hydraulic, which need heavier framing.
Floor and finish
Gravel, a partial slab or a full slab, plus any heated shop bay.
Machine Shed Mistakes We See Around St. Marys
We fix these problems in older St. Marys sheds all the time.
| What goes wrong | Why it happens | What we do about it |
|---|---|---|
| The new combine won't fit | The door was sized to the machine owned that year | We size doors for your next machine as well as this one |
| Doors rack and bind | The header over the opening was undersized | We use an engineered header and laminated jamb columns |
| An accessory building in town is rejected | It went up before the house or without a foundation | We check the city's foundation and sequence rules first |
St. Marys Farm Buildings We Build Most
Our St. Marys work centers on these four buildings.
Combine and grain cart sheds
We frame clear spans of 60 or 80 ft on laminated columns so you can park without dodging posts, with a big endwall door and a walk door near the shop corner.
Machine shed with heated shop
We wall off a shop bay, pour a slab there, spray foam it and add a mini-split, leaving the rest of the shed cold storage on gravel.
Lean-tos for trailers and carts
We add an open lean-to along one side for header trailers, augers and gravity wagons, keeping them out of the weather without enclosed floor space.
Acreage shops near town
On smaller lots we build shops matched to ranch or farmhouse homes with wainscot, gable trusses and dark or board-and-batten style steel.
St. Marys Machine Shed Questions
What drives the cost of a combine shed in St. Marys?
Clear span, wall height and the big door drive the cost of a St. Marys combine shed. A wider span needs deeper trusses and laminated columns, a taller wall adds steel and bracing, and a hydraulic or bi-fold door needs heavier framing than a slider. We list each item on our written estimate so you can weigh a bigger door against a lean-to or a slab.
How long will my St. Marys machine shed take?
Our crew time on site is usually a matter of weeks, not months, for a typical machine shed. Truss and steel lead times and the permit set most of the calendar. We plan around harvest when we can, and we give you a realistic schedule with the estimate so the shed is ready before you need it.
Is a St. Marys shed estimate free?
Yes, our St. Marys estimates are free and written. We measure your machines and yard, talk through door and floor choices and send an itemized estimate. If you want to compare a 60 ft span with an 80 ft span, or a sliding door with a hydraulic one, we price both side by side.
Do I have to be around while you build my St. Marys shed?
No, you don't need to be on the yard while we build. We meet you to confirm stakes, door location and floor height, and again at the final walk-through. During harvest we work around your traffic and keep the lane open. We call with questions and send photos as the frame goes up.
What permit rules apply to an accessory building in St. Marys?
Inside St. Marys the city issues the permit, and an accessory building over 150 sq ft needs a permanent foundation, slab or piers approved by the Zoning Administrator. Accessory buildings need 5 ft side and rear setbacks, can't sit in the front yard and can't go up before the main building. We confirm the current code edition with the city.
Does a farm shed outside St. Marys need a county permit?
Yes, in Pottawatomie County a farm building still needs a permit so the county can check floodplain status and setbacks. Kansas law keeps county zoning off agricultural buildings, but the floodplain carve-out stays, as covered in our farm exemption guide. If your parcel is on the Wabaunsee side, we confirm that county's process before we build.
Does every big St. Marys machine shed need a stamped engineer?
No, Kansas law exempts farm buildings from licensed-design requirements. The 14 ft, 42 ft and 60 ft triggers people repeat come from Wichita and Sedgwick County rules and do not apply here. We still build every shed to engineered truss drawings and bring in a Kansas-licensed engineer for large clear spans or when the office asks.
Who is the best company for pole barns in St. Marys, KS?
We think Topeka Expert Pole Barn Builders is a strong choice for St. Marys because we size sheds around your actual machines and put our footing, post and steel specs in writing. Ask every builder how they frame the big door opening, how deep they set footings and who files the permit. We answer all three on our estimate.
