This started off as just a reply to Tyler on my previous post, but since it was getting long and because he raised some very important points, I’m going to make another post as a reply.
Don’t worry, I haven’t kid myself into thinking it’s all a simple endeavor when it comes to design. ;)
My primary reason for getting this book was for ideas on the overall interior and exterior arrangements and of course I’m going to be as practical as possible when it goes into practice.
All the exterior walls are going to be 2 x 6 and the only interior walls will be around the bathroom which will be 2 x 4. I want to create “rooms” and provide privacy by using long curtains hanging from the ceiling rather than interior walls. Although there would still need to be at least a 6 x 6 beam in the center of the structure going all the way to the floor to support the roof in the middle.
I’m thinking of going with 2 inches of closed cell spray foam to prevent air movement plus Roxul bats for sound proofing and the windows are going to be triple glazed like you suggest. Yes it’s pricey, but because the overall structure is small, it’s still less than it would be for the average sized building.
There will definitely be rigid foam over the Tyvek wrap and, yes, I’m thinking of going with recycled cedar or a cement board product for the exterior just like the last pic (will have to figure that out exactly). The headers will be two 2 x 6 pieces each with insulation sandwiched in between and I was also thinking of going with a metal roof. Yeah I didn’t choose that pic by accident ;).
I think the most expensive part of the whole thing would be the windows and doors. I definitely don’t want to feel like I’m in a cave so the windows are a must.
I also want to use the landscape to my advantage.
I’m thinking of planting perennials on the South side so they will lose the leaves in the Winter allowing the Sun to hit the structure directly to warm it up, but will provide natural shade in the Spring/Summer by blocking the sun after the leaves grow back. This will allow me to have at least a couple of windows on the South, while the majority of them will be on the North side. These will have to be short trees so they don’t block the solar panels I’m also thinking of installing.
