We love the Rec Room open concept with the Kitchen sink, full-size refrigerator, pantry (with microwave), table for 6. We now have a coffee pot and a toaster down there for guests or for us. When our oldest comes home from the Air Force, he often brings the air fryer down there for snacks. Husband is refinishing a 100 year old pool table that is parallel to the kitchen table.
Husband did all the framing, wiring, plumbing, insulation, cabinet installation, lighting, and tiled the shower in the bathroom and the backsplash in the craft room. He installed the butcher block countertops in the kitchen area and in my craft room. We subbed out the HVAC, floors, drywall, paint, and trim.
The guest bedroom is huge and we now have a daybed and treadmill in there. I can even set up a full-size folding table for Christmas wrapping or other projects. It's perfect for a family with small children and our oldest loves the privacy when he comes home.
