sweet baby jesus. That is one solid abode.

What temperature does your family like to keep the thermostat at? Just curious.

So much to like, it's all very impressive. What is the ceiling going to be over those cross beams in the hallway? What will they put over the OSB on the fireplace? How tall is it to the peak in the great room?

Lol - Thanks Deezler. We are usually set at about 73 winter and 75 summer typically but that may change when we get our bills. I'm hoping I don't get too much of a shock. The entire house is getting spray foamed with closed cell foam. Roughly R38 ceiling and R24 walls. Window are all Low E with smart sun on the west facing windows. Heating and cooling is going to be geothermal. I think the load estimate called for 6 tons. We are splitting two units, one on each end of the house to prevent loss from long duct runs. It will have a total of 6 zones with one of those being the basement.

Just FYI if anyone is considering geothermal there are some great rebates available through most utilities along with tax credits. Our system cost before rebates and credits is $39,600. Our utility offers $750 per ton rebate and there is a 30% tax credit from the govt. Total cost after rebates $39,600 - $4,500 - $11,880 = $23,220.

Thanks Eddie - I am probably going to carry the tongue & groove over the timbers. Fireplace will be covered in the same stone that we are using on the outside of the house. Floors will be hickory with mostly heart wood. Floor to peak of the great room is 26-1/2'.



Edit: Hvac is 7 tons total not 6.

What is the sq footage of the house? Just curious. We too are using geothermal and our contractor did the calcs and all I think he is putting in 6 tons.

 

[EddieWalker]

What are you putting over the OSB to attach the stone? My only experience with real stone is that you stack it like bricks and use brick ties to hold it to the wall. This is real stone, isn't it?

Total sq/ft is 3700. We also have a total of 32 windows with most being pretty good size. Sq footage, type of insulation, windows, location etc will all factor in.

It is real stone but its sliced into thin cut veneer.. It will get a metal lathe and scratch coat plus mortar similar to the man made stuff.

That is pretty close to our square footage. We are using sips and we also have quite a few large windows. I did ask our hvac contractor to be aggressive with his calculations. I didn't want him to oversize the units too much. Exciting to see your progress. You are moving along nicely.

Are you putting the lathe over the OSB or will you be putting up 3/4 plywood first? My concern is with flex over time and the cracking of the scratch coat if there is any flex, which will lead to the rock loosening or coming off.

The current plan is to use lathe over the OSB. The chase wall is tied to the timbers all the way up seems pretty stout. The starter row of stone will sit on top of the timbers in each section helping with some of the load. The inside of the chase will get spray foamed with closed cell which will add some rigidity to the structure as well. Another layer of plywood may bring the stone out a little further than I wanted but I'll take a look at it today as an option for cheap insurance. Thanks Eddy.

Can you replace the OSB with 3/4 plywood? I like OSB for a lot of things, but it isn't very rigid. I'm sure you'll be fine with it in the end, but if you can do anything to make it stronger, now would be the time. What about additional framing behind it?
