This Wednesday the Pole Barn Guru tackles reader questions about the possibilities of post frame wall height with columns atop a concrete wall, interpreting client needs into engineer sealed drawings, and the scope of a barn to accommodate horses on the main level and an apartment above.
DEAR POLE BARN GURU: Could I build tall (25 ft) walls with poles at 6ft on center on top of an 8″ thick concrete wall, with anchors as required? I have never built with pole system; always stick framed, but I need the larger spans for tempered glass walls. Thanks for your advice. TARUNO in LA HONDA
DEAR TARUNO: In answer to your question….maybe. With 25 foot tall walls, an eight-inch thick concrete wall may not prove to be adequate. We can incorporate ICC-ESR approved wet set brackets into top of your concrete, in order to attach columns. Walls would need to be checked, by our engineers, to assure they would have adequate amounts of sheathing to properly transfer shear loads from roof to ground. We are able to provide columns up to 60 foot lengths, so your wall height should not pose a challenge.
DEAR POLE BARN GURU: Is your company or you capable of interpreting customer wants into engineered drawings for permits compliance? MARTY in CALGARY
DEAR MARTY: This is exactly what we do for roughly a hundred new clients every day, seven days a week, in all 50 U.S. states. Unfortunately for you, we do not currently have Candian Building Codes programmed into our system.
DEAR POLE BARN GURU: How tall would a barn have to be to accommodate horses on the bottom and eventually a 2 bed 2 bath apartment in the loft? JUSTINE in LITTLETON
DEAR JUSTINE: Before we get too deep into this, some things to consider: living above horses you will be faced with dust, odors, noise, insects and rodents. Most jurisdictions will require a two-hour fire separation between living and barn spaces, this means you have to have outside stairs and all structural supports for second floor need to be two-hour fire protected as well. You will have stairs to negotiate. Insurance is going to be very expensive. On to your question: Horses should have 10 feet of headroom, then thickness of your floor, 8 feet (or more) of ceiling height for your living space, then thickness of your roof system (raised heel trusses to blow in full depth of insulation from wall-to-wall will be nearly two feet thick). When all is said and done, you are looking at roughly a 22 foot eave height. https://www.hansenpolebuildings.com/2020/05/how-tall-should-my-eave-height-be-for-two-stories/
DEAR LESLIE: Thank you for your interest. Every post frame building Hansen Pole Buildings provides is fully engineered to meet applicable structural portions of the International Residential and/or Building Codes, as applicable. All components and connections, including foundations, are checked and verified for structural adequacy. Besides full-sized (24″ x 36″), site specific, multi-page engineer sealed plans showing each piece and how it is attached, you also receive engineer sealed verifying calculations.

DEAR POLE BARN GURU: Can a pole barn be used to create a backyard ADU (accessory dwelling unit)? My city allows them with rules and specifically said hoped to use modular to decrease construction noise but it seems that this might be a similar decrease in noise. However the issue is size I need it to be 400 which is the current minimum my house is 700 so my backyard is around 40×60. I would actually prefer a two story which could then have a smaller footprint perhaps 250-300 sq ft on each level with a simple porch lift between with an exterior staircase as back up and fire escape, or a two car garage with the ADU as the second floor. The ADU would become my home as I need a wheelchair accessible space. thank you. KRISTINE in GRAND RAPIDS
