this is what im talking about btw.

http://www.tuffshed.com/help_architect.cfm

tuff shed is kinda a famous manufacturer in houston... they make all these commercials wherein a motor cycle or some shit rides over a series of their sheds to prove how strong they are.

there's probably a dozen companies like them that offer similar services though.

as long as your shed is small enough to not be designated as a detached garage or what ever your issue is, im betting the companies engineer will cover you.

Tuff Shed offers the following services to Architects and Engineers:

  • Structure use - Exploratory Design and Material Specification
  • Budgetary Project Pricing
  • Written Product Specifications
  • Written Scope of Work Statements
  • Building Design
  • Foundation Design
  • Full Stamped Drawings and Calculations*
  • Elevation and Plan View Drawings**
  • CAD Drawings*

yes im sure you have built plenty of shit boxes. building things properly after all is the exception rather than the rule since home owners don't care in most cases. lowest bidder will always win the job.

site prep is very important for a slab on grade. its funny that you can spec a slab without even knowing what the site conditions are.

Funny how quickly you turn insulting.

Sheds & out buildings are not now nor have they ever generally been built to the same standards as housing, or even a detached garage. Building codes simply do not demand it & nobody wants to pay for it. Sheds are generally considered to be temporary structures.


even assuming he has very stable earth, and a well draining area. you at a minimum have to excavate all of the organic material and top soil, 6 inches in some cases, excavate more to allow for the compact able fill, compact aggressively, and then throw down steel.
If 1% of the sheds in this country are built that way, I'll fly to the moon on a pogo stick.


And yes depending on his climate, you absolutely should insulate the slab.

unless you live in the hottest of climates, you should at least insulate the perimeter. why? because it costs nothing. 1" foam costs something like 30-50 cents a square. thats 30-50 cents per lineal foot for a 1' deep footing.
Insulate the perimeter? Oh, OK, no big deal. That's not what you offered earlier, at all.

yes i agree an agressivly insulated slab is hard to justify in zone one 2 3 maby 4, but perimeter insulation, perhaps but for zone 1 should always be included in new construction.

when i was learning load calcs, i did the manual j for my moms old place, and found something like 800btuh heat loss estimated from the uninsulated perimeter. 800 btuh was nothing, around 1% of the heat loss, but when to take into account time scales, it does not make sense to omit such a simple thing, when it is so fucking easy to include in the form work.
You forget the purpose of the structure & what needs to be done with the heat generated therein. That heat needs to be removed, or even better, passively dissipated, like into the earth through a concrete slab. Heat flows the other way when the lights are out & interior temps drop. In very cold climates with deep frost lines you wouldn't use a slab at all. You'd use an insulated floor given the low load factor.

The prep I offered for option #2 is more than Tuffshed or most of their competitors would do. They build a solid product, btw. If they'll put one on your site, it meets all applicable codes.

yea i agree, however we are not discussing a simple shed. we are discussing re purposing or building something that what would ostensibly be considered a shed.

considering that the author has already stated that he is interested in 12"double stud walls, i think its clear that such outdated, and poor construction techniques are not appropriate.

the mention of insulating the slab aggressively was in the above context.

the mention of perimiter insulation was in the context of my lamenting how generally all slabs are terribly built, and of cheap offensive quality.

i thought that was clear, in hindsight however, maby it was not.

do 1% of the sheds in this country have plants growing within them?

concrete will not dissipate any appreciably quantity of heat. heat removal will be removed by means of ventilation or hvac equipment. no slab in the world would change that what so ever.

I see what both of u are getting at my terrain is flat And I have loamy soil. I have never insulated a slab here it gets hot as fuck in the summer and into 30's in the winter. I will do 2 x6 construction insulate the walls. I am shying away from the extra 6 in in insulation because I would lose that space on the inner diameter. But I think I can accomplish what I want with the space. I like the drain idea a poor mans septic essentially. Where I am putting this shed is essentially non-usable space it's narrow especially with the set back from the fence. So if it works well I can build another one...

Just build it In your attic. My friend lives in a small town In the country with no neighbors and his grow shed has been broken into atleast twice. Second time people his I. The field and scoped the place out for a bit. Attic is way safer. Sheds that vibrate, smell like skunk, and glow bright yellow when you open the door are hot spots for thiefs. I know your like wont happen to me but think you have to get rid of your product somehow and scum will eventually figure out where it's coming from. I grow In an attic and it's not hard to keep cool with a well designed insulated room and it's much safer. Plus imagine every time some one comes over you gotta make something up about why you have a new shed that buzzs with an a/c hooked to the side of it. Plus it seems like this shed will cost some coin and remember a lot of new growers become non growers quick when they see what it actually takes. Start out cheap and easy first to see if you have what it takes and enjoy what your doing.

True slot of things to think about

Indeed. I hope you've done this for awhile on a smaller scale. If not, I'd encourage you to do so to find out if it works for you. It's not for everybody, as there are hundreds of ads in Denver's Craigslist trying to sell used equipment, usually at unrealistic prices.

I can build a 10 x 12 ft space with no permits. I am thinking about putting two side by side.

County can demand that the sheds have a ten foot space between them.

A second shed would allow you to devote the first to flowering and you could have a small veg room in the back of the second with room for storage. But you put an air conditioner on a 10'x12' shed and it's a dead give away. If you do this, plant a shade tree on the southwest side.

10x12 is for exterior dimensions? that blows.

if it were me id build the shed at 2x4 to the proper dimension, then slam on 1 or 2 inches of foam cladding and be all like oh noes good sir, i hadnt realized.

you can get an r21-r30 wall easily this way. Foam boards are expensive though...reletive to cellulose anyway.

id HIGHLY reccomend you get a book on advanced framing techniques while you are at it...

less lumber and more insulation = a better wall.

I'm sure that varies by locality. A person could use the space to their advantage. Line the sheds up with each other. Face the doors & air conditioners towards each other, between the sheds. Set the air conditioners lower than usual w fasteners on the inside of the sheds. Build a 6' solid fence w/ gate between the sheds on both sides of the opening. Put a nice bright motion detector porch light on one of the sheds.

wait, so is there a limit to floor space? or a height limit?
because you could build something with 10' studs, and an aggressively pitched roof... like 45 degrees.

even better you could build a dual pitched roof, and build a mezzanine under the steep portion.... it might not be tall enough to stand comfortably, but you could perhaps use it for storage or some such thing.


yea the building would look absolutely absurd, but so what... if as you say, nobody is seeing this structure regularly it should matter little.

Take it from me attics suck!!! I spend twice as much on electric then i should space heaters in winter AC 24-7 in summer and still gets up to 90f

Get code guy out there to inspect, then, after approval, add your AC, and anything else that might cause "problems." Good luck. -granger

Yea I am thinking about all these options I was actually thinking about the sheds side by side like jhhn said tell me more about your thoughts on that subject.

I'd be sure to obtain a clear understanding about requirements for multiple sheds from local authorities, just for starters.
ask them about using a concrete pad as a base, too. Find out if a single bigger shed would have to be constructed to higher standards.

It'll cost more because you'll be paying for an extra door, 2 walls that a single structure wouldn't have, plus fencing & gate hardware. There will also be proportionately more load on the A/C systems in hot weather. You'll also double the number of water spigots & drains, probably want a fairly large buried pvc pipe electrical chase between the sheds to run lights on a flip flop if you want.

OTOH, you may be able to avoid inspection entirely. You could spread the cost over time by starting with 1 shed, adding the other later.

Whatever you decide, it's of the utmost importance to have your MMJ paperwork & compliance ducks in tight formation at all times. Otherwise, you're a trapeze artist w/o a net.

Yea I hear what u are saying. I think I will start with the one and add another down the road perhaps. Thanks for the tip. I will definitely make an entrance that u won't see the light when u open the door king of a double entrance

I had a grow buddy come over to my house and asked him what he thought. He said hands down he would want to do the attic. So now I have to really think about what I am going to do

Give serious consideration of at least a 10' usable ceiling height. Youll be able to run newer fixtures like epap or gavita. Even if you want to grow vert. At some point you may wish to grow trees like some sativas. You wont be able to in a short space. In my room i could grow a 7 foot monster if i ever choose. Any way you decide to grow is accomodated in a tall room. just my unsolicited .02. Take your time and consider all the ways and types of plants u may wish to grow. See my build thread and what i opted to do.
