Bagged is when you create large swirls that are textured over the walls. It is generally considered to be a cheaper looking finish than rendered. Although there was a member here who had a great bagged finish on her outside. But then I say it was great because it looked like render. Personally I wouldn't do it- it can look very rough if it is not done properly and it is a more dated look. So it could lower the value of your property. Even though you are just building and not thinking of selling I always keep resale value in mind

With our house the laws would now require you to have eaves or verandahs around that meals area. And they are right- we had to install a roll out awning over the doors in the meals area. The east sun was too much. Plus my only concern with the family room is your ability to see the kids all the time.
