Now that my HT is nearing completion (carpet guys come Monday!), I'm looking for my next project. We have a rather large deck on the back of our house and we live on the edge of some woods and it's bug central out there in the summertime. I was thinking of enclosing a portion of the deck to make a 3-season type screen porch out there. The construction seems like it would be pretty straight forward, however, I don't know what kind of footings are required for a room like this. I would like it to have a gable roof attached to the house, so I don't think the existing deck footings would be enough. Anyone here know anything about building a screen porch/3 season room like this?
