Concrete!

We have a few "hard" changes to make. We are adding two bedrooms and a bathroom above the existing garage. Unfortunately the bedrooms would be 10x12 if we used the existing garage footprint. So we are extending the garage by 5 feet and cantilevering the addition over the backyard 3 feet to provide the kids roomier bedrooms and a full bathroom. Also, as we change the interior we are moving toilets, sinks, and the kitchen - all of which requires jackhammering the slab, moving the copper water lines, and re-pouring concrete.
We did encounter 1 unplanned surprise - the existing garage was sloped. Since we plan to eventually turn this space into a living room and add a 3 car garage, we need to level out the floor. Here's the garage prepped for the pour:

And with the new floor:

The backyard sidewalk was a foot away from the house, with dirt and shrubs between the sidewalk and house.  We decided to pour the sidewalk all the way to the house to help with water penetration issues.  The new sidewalk is great - 6 inches below the interior floor, and sloping down and away from the house.  We demo'd out the existing, here's the sidewalk pre and post pour.

And finally, here are a few before and after shots of the reworked interior plumbing.  These first photos are for the kitchen island which will have our sink and dishwasher.



And since we have opened up the kitchen/dining room/living room into a large connected space, the old wall has been removed and we are putting in a step that runs the length of the new combined area.  Here's the mold before pouring the step.  The lower kitchen/dining area will be chipped, unfilled travertine in a versailles pattern and the living room will be Lauzon engineered hardwood in aged brownie maple finish.
