Costs to Finish Kit, Rebuild or New Build, and Size Recommendation

This week’s ask the Guru answers reader questions about the costs accrued to finish a home after investing in a kit, performing an extensive remodel on an existing barn or tear down and build a new structure, and a building size recommendation for a grow facility.

DEAR POLE BARN GURU: After purchasing large kit for residential home what cost can I expect to finish the house? I know a lot depends on finishes and stuff but I want to know if this is a realistic option. We will be purchasing land and we will be installing well and septic but I am just trying to figure building and finishing of house. LAURA in PEARLAND

DEAR LAURA: Assuming you are doing as much DIY as possible, your barndominium building kit is usually about 1/3rd of your overall investment (not including land, site prep, utilities and permits).

 

DEAR POLE BARN GURU: We’re looking at purchasing a property that has a large barn. Would it be better to use the existing structure and add what’s needed to make it a combination barn and residence, or should we tear it down to the frame and start from there? And if we do use this existing barn, would your company be able to modify a set of plans for our design? JEFF in OAK HARBOR

DEAR JEFF: Oftentimes it becomes far more practical to tear down and start from a clean slate. Structural upgrades need to be accounted for in making a barn capable of withstanding higher loads and deflection criteria for a residential structure. Should you decide to utilize this existing barn, you should engage a Registered Professional Engineer to physically evaluate this structure and do an analysis of needed upgrades. Combining a barn with a residence also results in fire separation issues, in some jurisdictions, this can mean up to two-hour fire walls, eliminating any ability to go directly from residence into barn.

 

DEAR POLE BARN GURU: My license is for between 2,501 square feet to 7,500 square feet of canopy. What size pole building would I need which would leave me room for drying, packaging, etc? DAVID in MAGNOLIA

DEAR DAVID: Most facilities we have provided have ranged between 6,000 and 10,000 square feet. I always encourage clients to erect as large of a facility as they can economically justify and fit on their property. 50-60% of your space should be dedicated to growing. Any less and it can be a struggle to be profitable, any more and ancillary operations become tight. Plan upon enough height to allow for two tiered growing (minimum 16 feet of interior clear height).

Proper Foundation and Slab, Two-Story Buildings, and Door Parts

DEAR POLE BARN GURU: Dear Sir, I read the details of pouring a concrete slab after building the barn. I live in Montana with some pretty cold winters. If I were laying a slab for a conventional stick built structure i would be required to dig footings 48” deep all around the perimeter. What should I do if I am building a pole barn? While I may supply low level background heat I would like a construction that does not require it to resist Montana winters.
Regards, DEREK in KALISPELL

DEAR DEREK: Regardless of the type of construction used, the success or lack thereof for your slab is going to come from what you do underneath it, as well as grading the site properly to keep water from pooling below it.

Follow along first by reading my series of articles devoted to site preparation which begins with: https://www.hansenpolebuildings.com/2011/11/site-preparation/.

You will want to have your building site graded so as there is a 5% slope away from the building, when completed.

Now the fun part – protecting your building itself. I’ve become an advocate for Frost-Protected Shallow Foundations. Here are a couple of articles which should get you heading in the right direction: https://www.hansenpolebuildings.com/2016/11/frost-protected-shallow-foundations/

DEAR POLE BARN GURU: Do you offer 30 x 40 2 story apartment/garages?? ROB in ALPINE

About Hansen BuildingsDEAR ROB: We offer any dimension of footprint you desire, not just 30 foot width by 40 feet long and would encourage you to look at what works best for you in an internal layout, then create the exterior dimensions which best fit your interior needs. Two and even three full or partial stories can easily be done with post frame construction and if your zoning allows the overall height and you are willing to add sprinklers, you could go four stories.

Your mixed use will probably result in having to at least one-hour fire separate the apartment from the garage. This could include having to protect the stairs, if they are interior, as well as to provide clear protection all the way to the outside world. A discussion with your local planning and zoning friends could provide you with added insights.

DEAR POLE BARN GURU: Do you have available, either metal or wood, a barn door and hardware for an opening 8′ high and 5′ wide, to be placed within a screen porch (the entrance to the garage)? TRISH in WIMBERLEY

DEAR TRISH: Thank you for your interest. Due to shipping challenges, we now only provide barn doors along with the investment into a complete post frame building kit. You might try contacting the ProDesk at your local The Home Depot®.
