Plans for a 15' x 33' garage & 12' x 33' lean-to carport

Hi Nur Hatice Kübra, I am looking to have a single car garage (15' wide x 33' deep) with a single car port lean-to (12' wide x 33' deep) attached.

I'd like to have the drawing created in a CAD type format.

1.) Please see idea sketch below (concept look only – this sketch is for a totally different size & type of garage)
2.) Overall dimensions (garage & carport) are 27' wide x 33' deep
3.) Dimensions - garage 15' x 33', + lean-to car port 12' x 33'
4.) Roof slope on garage is ~ 5/12 (not like sketch below)
5.) Roof slope on lean-to is ~ 3/12
6.) Garage door is on front (15' dimension side of garage) & is 10' x 8' tall
7.) Left side has 3 windows at 2'-4" x 4'6" - equally spaced along the 33' wall dimension
8.) Wall height of garage is 9'
9.) Wall height of lean-to can be less if it makes the roof slope (3/12) work better
10.) Man door to garage will be on right side & be 3' x 6'-8" & start 20' down from the front (not like sketch)
11.) 6" x 6" pressure treated columns for lean-to roof support
12.) Cedar shingles for siding
13.) 12" cornice overhang (not sure if that is different than what is shown)
14.) Structure will be on a slab foundation (footings, walls, slab)
a.) Footings will be continuous at garage perimeter (15’ x 33’) & be 2’ wide x 10” deep with 2-#4 rebar
b.) Perimeter block walls off of the footing will be 8” wide & be 40” tall (5 courses of 8” block)
c.) Top block will be type to accept a 4” slab

d.) Slab will be 4” with light welded wire fabric reinforcing


Please let me know;
1.) Time needed for modification (work days)
2.) Cost to generate plans



Thanks
