Home Addition's Foundation Question?

Hi,

I have a question on Home Addition Foundation. Currently I have a deck 12' X 44'. The deck is about 8' 6" from the concrete floor.

I would like to tear down the deck and build 22' X 28' Master Bedroom Suite with W/C and Bathroom. And the rest of the area will be a deck with 22' X 16' dimension. so that would be 10' X 44' addition to the existing plan. I hope you guy get the picture.

The area underneath the new master suite and deck will be some concrete floor and the rest is the grass ground. The concrete area will be the existing concrete area. I don't want to conver all the ground area with concrete.

What type of foundation do I need for this addition project?
Should I build the long square TEE (Spread) foundation? or can I just use the 6' x 6' post(column) with slab pad? Or is there any other way.

Thanks
Chai

I had 3 contractors giving me estimates and they all gave me different ways to complete this project.
Therefore I start to research and try to pick one contractor. I just want to get some idea and see which contractor is the most reliable.
BTW, the property is in Duluth, GA. Do you have any suggestion?

If you're looking to compare apples to apples for an addition like that, you should get a set of plans drawn up. That really is the only way to know for sure each guy's scope matches the other, so you can judge properly. If they are providing numbers and you have no idea what the details are on what they are installing, that's design-build, and you're basically a slave to the guy with the best pitch, and they can name what ever price they want because they control the scope.

I'd recommend you get a set of plans drawn up by a professional, and have them give you hard numbers.
