Greetings!

Sorry for the long post. I just started writing and it all flowed.....

I may be way over my head on this idea, but here goes:

I am interested in expanding my (attached) existing 16' x 16' garage to the *open* side, where the property will accomodate another 10 feet of space. My rough idea is to keep the current exterior wall, creat a single doorway through it, and have another "shop room" along the side of the exisiting garage. Space-wise, lot-wise, set-backs, etc, such an idea would be in compliance with local codes.

The roof would be the biggest challenge. The existing roof is a "hip" type of roof, and I would want to carry (extend) the existing look over any new addition I might be able to build.

Called (5) architects; only (1) was even willing to come out to my house and observe a small project such as the one I am proposing. Architech wants $1800 + $200 printing costs for a set of plans. That price seems steep to me, but that is not what has me frozen in my tracks. Architech says that he is not sure about extending that hip roof -- might have to open up the roof and extend a beam all the way down the ridge of the garage into the house portion (seems extreme) and that a structural engineer would have to be involved to perform load calculations. So.......as I understand it......first I hire an architech to conjur up a set of plans to the tune of about $2K, THEN I get an engineer involved (another $? cost), and THEN I determine IF this thing can reasonably be built? No way am I going to blow 2K plus just to ask a question.

I would like to try my hand at creating my own set of plans, and subject these plans to the review process. I might learn a lot along the way, and it has to be cheaper. I am envisioning a computer software program which will allow me to work on the design on my computer, then put the print-out on to a thumb-drive which can be brought to Kinko's, etc for printing on big paper.

Any ideas on the software? I want to be budget-sensitive here as well...?

I use the free sketch up for anything from bench design to building layout. Love it.

To echo the others, SketchUp is a great tool for your project. I drew in our existing house (using photographs with YouTube guidance) and then played with several designs for our garage. It worked great and this is what I submitted to the city for the building permit.

A picture or sketch would help too - from the description, it doesn't sound like that big a deal overall.

I found a free tool on bighammer dot com that was awesome, and easy to use. (i dont know if i can post the link, I have no affiliation with the site, but it made the plans for my detached garage in about 5 min that i got my planning approval with.)

Hope it helps.. sketchup was too much work to learn just to do what i needed

CadStandard is a relatively cheap ($37.50) CAD software that will enable you to draw any plans you might want to. You can convert your plans to PDF or numerous other formats that can be printed or edited by more sophisticated CAD programs. There is a bit of a learning curve, but if you have any CAD background you should be able to jump right in. And you will want some kind of drafting and architectural drawing knowledge before you design an addition anyway.

It seems like you should be able to design the addition as a freestanding structure that is attached to your existing garage, meaning it is structurally independent from your existing garage and house. If you did that and the load from the new roof trusses or rafters was transitioned down the new walls to a new foundation, I don't see why you would have to tie into any beam in the existing garage.

I have played with SketchUp and could do the basics. There are a lot of "tols" available. on the net.

The one thing I could not figure out how to do easily was put a gabled dormer on a roof and have it show up correctly from the inside.

Sketch up is about the best free one available. I'm an architecture student right now and we use it pretty often. Also use Auto Cad and Revit. They are big really expensive. Each has their positives and negatives.
