Grama's House | Passive Solar





 

We are actually in the process of building this one! It started out as a barn to house our RV and has gone through so many revisions! For a while there I was tweaking it 2 or 3 times a week. Had the friends who are helping us build this heads spinning!

This is a passive solar pole barn home. The deck across the front is actually a greenhouse. The whole house has a concrete floor with in-floor hot water heat. 



The kitchen is huge! We plan to have bench seating along the L shaped island with storage underneath. There will be plenty of room to store homeschooling supplies and teach a bunch of grandkids. :)

There is also a loft above the hall/closet/bath and laundry room area that will be accessible by a steep ladder/staircase. It is 4ft. high at the center and goes down to 2ft. on the north side. It sticks out over the garage a bit. Lots of room for the grandkids to hang and sleep!



There is a tiny second bedroom on the northwest corner. At first, it will probably be used as a bedroom for my grandkid who wets the bed so Grama doesn't have to navigate those loft stairs with wet sheets every day, but later on, we will probably use it for storage. 

The smaller bath is a shower room with a toilet in it which will double as a storm shelter. 

If I wasn't so adamant about my hubby having a mancave to retreat to, I'd build another bedroom or two in the garage area and leave the entire south side as one big room, but he really needs a place to escape from the grandkids! He recently decided to put in a glass patio door instead of a garage door just because it will be warmer, but we went ahead and put in a frame for a garage door in case we ever decide we want one there. The patio door will be big enough to get the tractor into on really cold snowy nights and that is really all we need right now. He is putting in a hoist, a floor drain, a stainless steel sink, and a stainless steel table so he can butcher there. He also wants to use it as a summer kitchen for canning with the doors open when it is hot.

All doors are 36 inches wide so the main floor will be fully handicap accessible. We also have double doors between the great room and the mancave so we can open it up to have more space to entertain. 

The greenhouse will have a black block wall along the house side with insulation between the blocks and the house proper and a 2-foot deep gravel/sand/patio block floor for heat sinks. 

Under the roof, we put a layer of reflective foil insulation, then 1 1/2 inch foam board insulation and we are still going to add 16-inch thick roll insulation. That will give us a 48.5 R-value in the ceiling. The walls will be the same, except without the reflective foil. 

We plan to have a mini-split system for air conditioning. But we are also putting in a whole house fan. We think if we open the windows at night and use the fan to pull the cool night air in and close the windows during the day, we shouldn't have to use the air very much.  

Here's a picture of the house today. Stop back by! I will be updating this as we go along.



Here's the east wall with the patio doors to Grampa Tom's workshop.

OH MY! It looks like I haven't updated this in quite a while! We have been living in our house since September 1st. We didn't get the boiler installed and working until just a few days ago so we have been heating water on the stove and running space heaters. Today, we are redoing the roof insulation. A few days ago, we discovered that the pink board above the bat insulation was wet with condensation. In researching how to fix it, we found that we absolutely had to have spray foam insulation on it. So we are pulling down all the batt insulation and foaming it. We will put the batt insulation back up after it is dried. By the time we get all this done, our roof will have an R50 insulation value! 

Here are some pictures from the week before we moved in.  Apparently, my old film-oriented mind shut down on taking pictures once we moved in. When I can get back in there, I will try to remember to do a walkthrough for you!
