I’ve got a job to bid–rebuild shop on existing slab foundation (slab is level and in good shape)
Client wants it bid two ways, one with simple trusses and no storage, one also with a bonus room with dormers–which I’d also get a truss built for.
Building is to be 32×16, with 9′ ceiling below.
Height restriction is 20′ from grade to middle of gable end from top plates to ridge.
My question is, what’s an optimal roof pitch to create a usable space with a couple dormers?
The shop and the bonus room above are not to be ‘living space’ so I’m not concerned about insulating, egress etc…
This is my first opportunity to cut my teeth with my new copy of autocad… been teaching myself to use it.
Any general guidance welcome, thank you.

If it is to be a BONUS room then there won't be any extra charge for it. Otherwise it would not be a BONUS.
JUst ignore my personal pet pevee.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
huh?
If the client has to pay more for the room then it can hardly be called a BONUS..

Ok, I think our wires are crossed as to what I mean by 'bonus' room. I guess in new constr it's sold as a 'bonus' but I'm speaking in terms of, "I can build it this way or that way and here's the difference in cost."
My question was really only of what I would have to do to the roof to get a usable space up there with only a 16' wide building.
Client's wife wants a sewing room, and I'd give access by simple pull down attic stairs inside, or exterior staircase and door. Dunno yet.
You're talking about trying to get living space above a sixteen foot span? First thing I'd do is to cantilever the trusses about four feet over each side wall. Then a 12/12 roof will give you about a ten-twelve foot width of headroom upstairs.
You could put the stairs in the back of the shop and use a corner landing to gain the needed height.
you fogot his heught restriction. i think a 10/12 would work

You're right, with the cantilever it's twelve feet plus nine, isn't it? He could do 10/12 or use 12/12 and limit the cantilever to three feet or...he could also limit the garage/shop level to an eight foot height.

Trying not to high jack your thread but trying to help out.
My parents did a room over shop.
So here are some pics.
Think separate access to the up stairs to keep out dust etc....
These two shots are from the outside of the shop/craftroom.
Ey!
Very helpful. Thanks for the photos.
I know if I show client's wife your mom's craftroom, it'll be a hitch!
The roof--it's stick framed? How big is the beam above and what's the span?
Rafters are?
Thanks again,
Pat
The beam is a doubled 2X14 LAM
the roof is stick framed.
Span is 16 feet.
This was a rebuild inside an old frame to be able to get around the city bylaws as to the number of units on one property.

I'm fine too as long as the building is not habitable (ie doesn't have eating, sleeping and bathing facilities together--laundry ok alone, bath ok alone that sort of thing), I follow the height restriction and don't cover more than 50% of the lot.
I'm really hoping to have a truss built so I can just get the walls up, and bang the roof is done.
I saw a similar place in town and the trusses had a 2x12 floor joist, a 2' or so vertical member at the heel and then 12/12 pitch with a collar tie like ceiling member to form the 'bonus' room (sorry billH)
I think I'll just head over to the truss guys and get their suggestions.
I really just need to know what to start drawing to get plans done and trusses built.
THanks,
Pat
Inside the wood shop and the dust collection I rigged up with an old furnace fan
That's a really nice space - must be a pleasure to work in.

Mom's craft room from the inside
Here's an approach I've used, when I wanted to get attic room and keep under a certain height and still look good - Basically increase the roof pitch, and have an "invisible" flat roof section in the middle hidden from the ground -

Just for grins, here's a copy of the AutoCAD R14 working drawing I actually built the addition from - a real mess, with changes and details, 'cuz permit drawings came offa' this, too -
Forrest
Thanks for the drawing. Useful to look at your settings and stuff. (I've really just started teaching myself how to use the program.) I have the program, and David Frey's "Autocad 2002 'No Experience Required'" Seems to be a good book for figuring out how to draw simple buildings... He takes you thru a 'cabin' project...
How do you separate the layers--your framing plans are smack on top of other parts of the drawing>?
Do you do siteplans separately?
Wait - there's more!
Found this of the interior of the loft during construction. The little wall with two openings leads to the shed dormer area -

Oh, yeah. It's "bated" breath. As in "abated". I've often said "I'm waiting with worms on my tongue, but nobody ever laughs"
;-)
Forrest - just trying to get my post count up!
“Every eye fixed itself upon him; with parted lips and bated breath the audience hung upon his words, taking no note of time, rapt in the ghastly fascinations of the tale”.
Yeah, I ought to have known that. English Ed degree. I naturally assumed that the etymology of "baited breath" had something to do with luring your conversation's quarry by way of exhaling some supposed attractant....................
What I like lately is the explosion of 's. Everything gets apostrophe "s" now.
For example: "puppie's for sale" or "free bag's of nail's"
I think it bled over from acronyms getting apostrophe-s for plural, like "SUV's"
Night,

We love this book - http://www.amazon.com/Eats-Shoots-Leaves-Tolerance-Punctuation/dp/1592400876.
I just turn various layers on and off - the reason everthing is stacked up is so I could turn on appropriate layers as needed for the various permit drawings. Sometimes I'll draw a second floor directly over the first floor to see where walls line up, particularly on old vernacular houses with additions, where nothing really makes sense.
Forrest
Oh yeah, and one more thing?
uhhhh

I, uh, still have to be your secret Santa. In the mail tomorrow, I promise!

The art of re-gifting, eh Santa? Let's see here, what did I get that I don't need and won't be missed if it disappears? Ah yes! That Ryobi 3/8" drill. Hey, maybe I can wrap it with that Rush Limbaugh necktie I got from my BIL.
AHA!
bad santa.
(I sent mine out two days ago!)
Thanks for the input, though.

Look into raised heel trusses.
I was throwing some ideas around here and Bosshog turned me onto the idea. I was planning on cantaleivering the trusses. Using the side wall of the truss as the bearing point on the exterior wall.
Woods favorite carpenter
exactly, I resp to another poster that i'd seen that on another job around town. Matter of fact, I think my pella window guy might have those plans i could sneak a look at.
I think I saw the trusses up when i drove by one day and it looked like they had 2x12 joists for the 2nd floor and a vertical member for the heel--a collar tie-like ceiling.
thx

I was going to say what Piffin said--gambrel roof. I'd think it'd be easier to frame, plus it allows for a less cut up space inside and less messing with all the cutting and fitting when drywalling.
