1.) It’s desirable to keep all the natural light, but seems somewhat unrealistic to me - currently, there are 3 4x3 and 4 6x3 single-pane sliding windows back there, leaking out all my heat in the winter. I don’t think I can afford to replace that kind of footage with double-pane, so I’m weighing the possibility of removing about half of the windows back there and just keeping one end of the room nice and sunny.

2.) My house has no central HVAC. There’s a through-wall unit back there now, which I replaced about 5 years ago. It’s sufficient to cool the majority of my entire house on its own, though it leaves something to be desired as a heater. Installing a complete central HVAC system is presently out of scope, so I’ll have to stick with the through-wall unit for now.

Started the process of exposing the interior wall - this would have been the original exterior wall of the house, before the patio was closed in.

This all looks relatively healthy to me so far, though this is only one four foot section. I’ll proceed towards the corner, once I find a home for the stuff I have stored back there.

I think this is a good idea but I don’t think it’ll be workable for my space unless the entire structure comes down.

How do you mean, raise the floor? I believe the concrete patio floor was poured as part of the foundation of the house.

Most of the circuits were wired with 12/3 already but with the ground wire not hooked up to anything. The electrician replaced the service panel, hooked up the grounds and installed new three-prong outlets. The circuits that were wired with 12/2 got GFCI outlets.

Had an electrician go through the entire place when we first bought the house so we could get safe three-prong outlets in place of the two-prong ungrounded outlets that were originally there. Didn’t do a full rewire because there’s no ceiling access - originally, the only heatsource for the house was electric radiant ceilings, though a couple baseboards were installed at some point after initial construction. The wiring for the sunroom’s A/C is run through a conduit on the outside of the house. I replaced the original through-wall unit shortly after we moved in, and I’ve seen that whole circuit.

What about the interior wall, against what used to be the exterior of the house?

Yeah, when we first moved in the plan was to put in an alternative heat source so we could use it as combination exercise / office space. I’d really like to be able to set it up that way - I like the view the sunroom gives but I really need more year-round floor space so I’d be willing to lose the sunroom functionality completely if I had to

Had to hit pause on it this week, but recently I have been working through Final Fantasy IX, the PC remaster on Steam w/ Moguri Mod. Started my playthrough in early September, and I just got the boat and entered the grindy minigame hell portion of the game.

My old house from the early sixties has electric radiant heat in the ceilings as the sole heating source, a large sun room running the length of the house, and almost no insulation to speak of. I’m in Ohio.

Incidentally, when we moved in, the inside doors of the cabinetry were all wallpapered in newspaper clippings about the 1970s energy crisis. I can’t imagine why!
