The felt is on...

...the roof. They'll put the shingles up next. Then they still have to cut out some window openings, most of them are already framed internally, so they can put the windows in and get it sealed up and start heating it and working on the interior.

In the photos, you'll notice the three south facing window openings on the main level are in. The entry door to the outside will be between those windows and the patio door in the existing house. They expect the addition to be sealed up by the end of Tuesday.

One day I'll figure out how to get my glove out of the view.
