It's pretty easy to determine if an enclosed sunroom was once an open porch. Look the the wall of the room against the interior of the house. If it has been enclosed at a later date, you will find it was once an exterior wall. That can be determined by finding windows inside the sunroom to the interior. The thickness of the interior wall. A slope to the room floor, indicating it was built to let water drain. A difference in the floor's level compared to the next room, and yes, the ceiling being finished off differently than the rest of the house. I also see exposed brick under the corner posts. My guess is yes, this was an exterior porch and enclosed.

Thanks for the replies. I went back to look at the house and there were roofers there - guess the bank realized how bad the roof was and decided to fix it even though listing was AS IS. Decided agains this house - put a bid on another - needs help but definitely in better shape!! Thanks again!

I don't understand the island, dining room table and bar - are any of these built in? If the entertainment center is built in where you show it- you will need chairs to face it. You can have some conversation chairs facing the couch but day to day it will need to be where you have it.

If teal isn’t doing it for you that blue color is really pretty too and still would look gray with brass and the grey floor tile! I found a few good options on amazon for the hardware by searching brass square pulls and also these on way fair: https://www.wayfair.com/Hamilton-Bowes--Ventoux-5-Center-Bar-Pull-24128SB-24128SCOP-L1123-K~HMBW1035.html?refid=GX293766718941-HMBW1035_40348394&device=m&ptid=762818256643&network=g&targetid=pla-762818256643&channel=GooglePLA&ireid=83020192&fdid=1817&PiID[]=40348394&gclid=EAIaIQobChMIsbjP3fmW5AIVgrfsCh1oWwbcEAQYDSABEgIS_PD_BwE Here is a link to a similar light fixture! https://www.bellacor.com/productdetail/elegant-lighting-ld6042br-eclipse-brass-and-frosted-white-12-inch-one-light-pendant-2116486.htm?partid=googlePLA-DataFeed-Pendants-2116486&kpid=2116486&utm_source=google&utm_medium=cpc&utm_campaign=Shopping_-All_Products(NEW)&utm_term=&utm_content=multi-converters_(2-5)&gclsrc=aw.ds&&gclid=EAIaIQobChMIv_64qPqW5AIVFKrsCh0HGQGgEAQYCCABEgJyK_D_BwE I think the subway tile will look classic and gives you more leeway to get a countertop that can be the star! If you picked the geometric backsplash I would say go for simple very toned down counters.
