The quanset hut kit cost us $8500 from steel master. Its 34x30.
The concrete pad is 35x31 for a total of 36 yards. We paid around $110 per yard. Rebar, plastic, form boards (2x12), etc ~ $6000 materials for concrete.
Equipment rental (1 week) - excavator, power screed, power trowel $1000 (we got an employee discount on equipment rental).
We reused the 2x12's to use as headers on the end walls for the doors and eventual porches on both ends.
Windows and Doors - ~ $1000 (we got a deal on the windows. They were custom ordered by someone and returned)
metal siding, screws, lumber, etc. ~ $2000
If I added in the plumbing (drain system to septic tank), running the water hydrant, electric from pole to pad etc that needed to be done prior to pad being poured we are probably right at $20,000.
We are having the entire building spray foamed for $5000.
We have done everything ourselves so no labor charges. We have an old barn that we are going to tear down and the tin and barn wood will be used for the interior. We already have all the appliances. We already have kitchen cabinets. So i think with another 10k we will have the inside complete (excluding the loft areas above bedrooms, bathroom, and utility room).
I'm going to acid stain the floor. So no expensive flooring to buy.
We are going to heat and cool with a minisplit. ~ $2000
I think we will be around 35k when its all said done.
