Thank you for feedback! If it's ok with you, I'll answer most of this in msg, since what is posted here on permies is basically JUST a quick sketch of the basics, to show what I'm doing. It was already too long of a post, I heard a LOT of tl,dr.
Most of what you mentioned IS addressed in the actual design.
A couple of quick points:
After watching the house exterior wall video I finally noticed all those wonderful trees. They are going to affect the heat portion of the sun's rays striking the house walls
That is not my house, or my property. I have no trees close to the site.
And going back over the drawings there seems to be an absence of a spot or place within the home with a large window - possibly two - to sit and watch the world on days when walking through it isn't motivating enough.
That one is priority! The basic windows are 3 foot wide by 5 foot tall, and there are 5 on the south side, 2 on the north side, a 6 foot wide by 3 foot high window above the sinks on the north side, and a 4 foot by... I don't recall right now, big enough for emergency egress, on the west side of the north bedroom, door on the west side on the south bedroom. The clerestory has 7 4 foot wide by 2 foot high windows (some of which open) and there are high windows in the wall between the bedrooms to bounce the light (but not the heat) into the north bedroom. The basement has more of those 3 foot by 5 foot tall windows. This house bounces a LOT of light around!!
Your seven foot ceilings may provide minimal benefit but in actuality will impede air movement and, in the event of a fire, reduce breathable air due to the forced fire gas cloud expansion and reduce time available to evacuate.
The 7 foot high ceilings are only the pink rectangle on the floor plan, the bathrooms 10 foot of hallway, and the utility room. All the other ceilings are cathedral.
You have mentioned the first physical structure burned for unknown reasons. The second structure, a single wide model home, due to electrical issues. Both structures burned "into the basement". This tells me a number of things. Firstly the house was occupied by a financially and time limited person or persons. The house probably burned due to faulty fireplace, wood stove or chimney issues. The electrical issues were probably related to overloaded circuits - possibly in the winter time when we all consume more energy.
I have learned since I wrote that there WAS no first house, it was never built. The double wide modular was faked onto the foundations that were built but never used. It burned in summer, due to a faulty water heater, and took out just the bathroom and utility room. The modular was a rental, and it decided to move the tenants into another owned by the same landlord, and scrap that one, and sell the land.
Anyways. I would LOVE to have your advice and oversight on my plans, I'd LOVE it if you have time to talk to me about this, and look over my plans etc. Like I said, this was just the parts I thought permies might find interesting. I REALLY appreciate you taking time to write what you did!! :D
I curtsy nicely at you again!! :D
