I too was able to build my bar before the kids came. I am not a carpenter, but I am very patient and love to work with my hands.
This bar/room took me 9 months of evenings and weekends and I did it completely alone except for hanging the flat screen (the gold frame is a tv) and plumbing the bar sink, so i take a lot I pride in it.
The walls added a nice touch as they are mud plaster and give that German inn feel. Glad I got it done before the two kids came as I can barely squeeze out a brew day anymore let alone tackle this.
