Frame in carport section

Hi, first time homeowner here. I have a detached laundry room/storage room under my carport and want to attach it to the house. There is a door on the side of the house for access. The footprint would not interfere with the existing iron columns. I basically just need to match (raise) the floor elevations and add 2 stud walls.

So, in the picture shown, I would tear down the visible white wall and a short wall to the left of that. Then add a new wall from the brick veneer to the iron column line and frame in that portion (including that little area where the pallets are).

Is this not going to be as simple as it looks? Is there an easy way to match the floor elevations? Would i need to fortify the foundation under the new stud walls? I wouldn't be adding any load to them. And the new slab area would be seeing foot load as opposed to car load. Please let me know your thoughts and potential concerns!

 

First, examine the existing structure to see if any part of the storage room is load bearing. I assume that at least the back right corner will be.

Then look at the ceiling heights inside the house and under the carport. Are they the same? They usually are but check just to be certain.

Then it's a question of are you going to get permits for this work? If yes then you need to follow their guidance. If only dealing with non-load bearing walls they might even say you don't need a permit though one would probably be needed for the plumbing and electrical work.

As for being easy it mostly is. The back corner that I suspect is load bearing will be the first gotcha but it should already have a footer in that location.

How high will your new floor be off the concrete slab? The current minimum for a crawl space is 18" free height (from concrete slab to the bottom of your joists) which I suspect will be too much. So, then what do you do with the space underneath??? It really shouldn't just be closed in because of moisture problems so ventilation might be needed at the minimum. If you get freezing temperatures this won't work for a laundry room as the pipes may freeze.

 

Thanks so much for the advice, Ceiling heights are the same. I will get permits. The back and right walls of the current shed will remain, so no messing with that load bearing corner. I only need about 6-8 inches of raising the floor, so i guess i will just form and pour some concrete and WWF over the existing area. And no freezing (Louisiana). The plumbing and electricity are already located in the existing shed, but i may add a half bath. Should be a fun project that will add 150 SF to the house.

 

You will have to research where your drain lines are located and how large the pipe. A toilet will require 3" minimum and will have to have proper fall/slope so unless you are lucky and your main drain line runs underneath the laundry area it might not be an option without adding a sump and pump.
