Draw plans, get a material quote from your lumber yard , get quotes from any sub contractors like electricians and excavator guys etc, add them all up then 10% to this number then double it and you mite have enough. Having been in the building trades for over 40 years I have rarely seen a project come in under budget. There is a tendency for most people to make changes as they go and none of them ever seem to make the job cheaper. I built a garage on a house I was flipping a few years ago and did 90% of the work myself and it still cost 25% more than I had planned on.

 

I built my 1200 sf shop 12 years ago for around $10.00 per sf. I had the 4" slab poured and I did all the rest. The shop is 24'x48'x10'. The roof is metal; 200 amp service,salvaged A/C - heat units; two sliding doors; full insulation; factory trusses. Today, the cost would easily be double. This is in South Mississippi. You started this thread almost 2 years ago and you haven't started it yet? The longer you wait, the more expensive it will be.

 

I spent $1,700 on a concrete slab with a rat wall for the foundation. In my area foundations are at least 36" deep. The apron cost me $1,200 for the concrete alone. So that's $2,900 just for concrete without the labor costs which was another $6,000 because of the earth work required. For you a 12×20 slab would cost about $330 for the concrete without the foundation included. Depending on were you foundations maybe required. I have close to $22,000 in my 30×33 detached garage.

 

U revived a thread that has been dead for 5 years…... at this point I hope he already has his building finished. Lol

 

too bad. Wanted to see how it ended.
Read through some of Woodmaster1's blog and forum and projects… no mention of getting around to building that shop. Last update was around 2014.

 

$1000 will cover the permits here.

 

Charles, I feel your pain! I used to love doing those building projects. now-a-days it's torture.

Woot… I wish I could build one for 2000. I got a 12×16 I started last Fall and still haven't finished, got all of 3600 in now with at a minimum of 2000 left to go… All that with a wood floor. If asked to build it for someone, I'd have to be in the 12.5 to 14k range

Knowing CJ I am not sure, the post was from 2013, he'd been talking about a flood proof shed for almost 10 years prior to that. His parents back yard evidently becomes a drainage ditch with heavy rains.
