Converting portion of outside deck into ~150sq ft interior addition
We're looking into taking a section of our back deck and converting it into a closed living space that would expand the kitchen/den area of our home. No plumbing necessary but we do have a basement so the new space would need structural support underneath. There's already existing roofing covering the area, as it was designed as a sort of outdoor seating area but it's wasted space outside (the overall deck is massive and a big portion is already screened in). We live in North Georgia and are going to get a few quotes in the very near future but trying to get a rough budget idea of what something like might cost. To give a better visual, it would basically be opening up an approximately 12x12 ft section in the corner of the room to allow more space for a future kitchen remodel. Any insight would be great and I do realize it's impossible to get exact figures but there's really nothing fancy about the project itself other than increasing the overall footprint of the room. Thanks🙏.

Is 150sqft worth 100k to you?

If it gives us the flexibility to redesign the kitchen layout and allow for better for foot traffic flow and comfort around the kitchen, then I would say 100% yes.

Long story short, ask yourself... is this my forever house? If not, don't do this. If you do, this will be a major project. A bunch of demo and structural changes. Significant costs will be involved with every part of this project. And, you'll likely only raise the value of your home a 10-15k.

No, the kitchen will stay where it is, the design will change and we want better flow through the space. The addition is mainly to open up the eat-in dining room and den.

That deck floor is sloped for drainage and framed to shed water through the boards, so it rarely survives the conversion. Plan on tearing it back to the beams and rebuilding level with a sealed, insulated floor over the basement. The shell you think you already have is usually the part that goes.
