With the tusses up, the roof goes on, the urgent goal to keep the weather out.. I did have some minor water damage to the floor plywood, but easily repaired.
The new structure will have a two-story foyer, with a stairway to the second floor, and a balcony around the perimeter of the foyer. My master bedroom will have french doors opening onto the balcony, overlooking the stairs and foyer. The old kitchen overlooked the back yard and pond, with only one window, the old family/TV room overlooked the driveway.. These have been reversed in the new structure, the family room will open onto a 32'x20' deck overlooking the back yard. The new kitchen will be in the 12'x21' 'pop-out' adjacent to the driveway.
The whole new structure is built on virtually the same footprint of the old house. The added living space is mostly the upstairs which will be a library and a 2nd story laundry.
The new structure will have R27 walls and R50+ ceilings. The heat will be hot water heated floors, the main floor a 1.5" 'suspended slab' with Pex tubing on 6" spacing. The second floor will have sub floor pex tubing on 12" centers, I am not expecting to need much added heat upstairs. The flooring on the main level will be 75% natural slate, and the remainder 1/2" engineered, prefinished wood. Both of these flooring products will be installed on the concrete suspended slab.
I have been working [flying] a lot, so I've had to just rig up an extension cord to run the circulator, and a thermostat to trigger the primary pump to keep the water up to temp. So far I'm keeping the main level at 55*, the heated floor seems to be at about 60-65* to accomplish this, depending on outside temps and winds.. the building only has 1" of foam on the walls, only R7 insulation for now. There are no ceilings, the rooms are open to the ridge peaks, and the eaves and peaks are vented, so the house is not 'air tight' yet.. But it is amazing that the main floor is comfortable with the floor at ~60*.
I can't wait till I have the time to wire the ceiling lighting, and get drywall on the ceilings.. then the house will warm up considerably.
More to come.
