Time to revitalize this thread. The house is coming along nicely. The exterior is almost completed, and they just finished hanging the drywall inside. It's cool walking through and seeing rooms instead of being able to view across the whole interior.
I don't have any drywalled tank room pics yet, but I do have some updates since the last photo.
Here are some more framing shots. This first pic shows the family room, looking toward the fireplace. On the left are 3 arches, and the new tank is going to sit beneath the farthest arch to the right.
This next shot is looking at the tank room from the corner where the tank will sit.
You'll notice that the column that completes this arch is gone. It was cut away (since it's not a structural column) in preparation for the tank installation. Once the tank is in place, the column will be rebuilt, and the wall and cabinetry will be installed around the tank. I hope they don't scratch or otherwise damage the tank!! The vertical pipe in the center of the room is where the floor drain will be located.
This next image shows the curved wall that covers the back side of the tank room.
Here the tank room has been insulated and is ready for drywall. You can appreciate how the tank room is sunken below the rest of the 1st floor slab in the event of a catastrophy. You can also see several of the outlet locations, including the ones I put in the ceiling for the lights. Each of those ceiling outlets are on a separate circuit, so no two MH bulbs will share a circuit.
And just one more shot of the tank room, inulated and with the ceiling drywall in place outside the tank room. This photo also shows the dual ventilation ducts that are in the tank room. These will vent to the outside and both will have fans controlled with temperature and humidity sensors. You can also see quite nicely how that 2nd column was cut away.
