One more wall to enclose, but that is going to include a door. A bit more tricky to do.
Next step is super easy....exterior siding. Cut, nail, and caulk. Zip...done. Trick -- design the wall so that there is nothing but straight cuts. Avoid complicated bits and angles. In this wall, the trim will handle any gaps in the siding.
The game plan :
...install electrical outlets
...apply cedar T&G on the interior walls
...trim out the room, inside and out
...sand and paint the ceiling rafters
...remove the two sliding glass doors between the livingroom and this newly enclosed porch
...install the flooring in the livingroom and enclosed porch
I still need to sit down and decide about the flooring. Got the livingroom decided-- 6"x24" tiles that look like wood. But no decision yet for the enclosed porch. We're leaning towards sheet goods of some sort.
