This thread rocks.
Would love to own a small patch of land and build my own mega efficient, self sufficient place. This thread is very inspirational.

Just bought 20 gallons of good quality exterior paint for $150 on CL. I'm trying to project out about a year toward what I will be needing to buy and trying to get it beforehand at a lower price. Things like paint can really add up if you buy them at retail prices.
Other stuff like drywall I'm buying new just because it's heavy and I need it to look nice. I'd prefer to just schlep it once and not have to move it around too much.
I could have cut the roof cost if I cobbled it together w/ mis-match metal pieces but $1,000 + later the roof will look good and I can absorb the hit.

I should change the title to the $40,000 house but the basic idea of buying things about a year in advance of when you'll need it has certainly kept the materials list cheaper. The latest goodies were a used Porter Cable Pneumatic flooring nailer for $175--I figure I can do the job with it and then sell it for a bit of a loss so the next person in line can keep it going.
After reading alot of books I concluded that basic wood frame construction made for a good solid home. It was within my skill set, I could make it warm and snug. And the materials were available. Not as sexy as the TImber frame stuff or the Straw bale but I was able to put the roof up myself.
Not too much going on right now--The snow has been pretty good down south so I have not been north working on the warming house.

R values
Recent studies show R26 thermal mass buildings out preforming standard built homes with R56 insulation.
So if tests on straw bail homes with thermal mass interiors were ran I would expect similar results with other thermal mass systems using foam.
As for flooding what other energy efficient system can preform like a concrete and foam monolithic SCIP home?

dave- you don't want load bearing straw, i have built 3 straw/cordwood structures and the infill is the way to go.
Depending on where you build, 25K for a septic seems really high.
pm me if you want

I'm bumping this thread.
My wife and I have been looking for a house but are having a hard time finding something in our area that we can afford. The thought just occurred to us that maybe we should use what we have for a down payment and try and find a lot and build a straw bale home. We don't really need anything large we're thinking around 1500sq'ft.
Doing some research today we found that its going to be around 17,500 to 25,000 for the septic, couldn't get hold of the well guy. The septic guy said all earth work, grading, septic, building pads and digging footings as a base price he threw out 50G's. I'm hearing the well could cost around 25g's (but dont know cause like I said up there).
Dave,
I am currently building. 17500-25,000 for a septic is out to lunch, unless it is a very special system that is engineered and in some restrictive type of soil layer. My simple gravity system for a 4 bedroom home is about $6k. My well at 240 ft depth with the pump was $15k.
I dont know where you are building but those dollars you were quoted are crazy and totally unrealistic around these parts.

R values

Rich,
I don't doubt that thermal mass within a structure will help the home stay warm longer than without but I believe you are mixing intrinsic characterisitcs.
The R value is defined as 1/ (the overall heat transfer coefficient). All other factors the same a higher R value means less heat transfer.
Of course if you throw more HEAT into the building then that is a factor but bifferent than comparison of heat transfer values.

The foam block system salesmen have tried for years to conjure really high "R" values but so they can bash frame walls. This has some validity but high mass walls have much more of an effect if there is a dominant cooling load vs heating. If not, the thermal mass salespitch is just that...

My bro outfitted a 53' cargo container.
Pimp and it was around $16,000 total.

Perhaps I did not explain.
The performance argument between "thermal load" and R values can be explained this way:
You have two climbers, dressed the same, same height, build and fitness level. One is starved. One is well fed with all the calories (heat) you can get.
It is obvious which one performs better. But this is not about the the R value. It is not about the down coats they have on.
If what some people are trying to say is that there is an R-Value of diminishing returns, then yes there is.
Overall building performance involves two simple concepts. How efficient is the heating and cooling system and how well is it insulated? Thermal mass is a way to hold and release the heat during times where it may not be gained (sunlight) which fits into the efficiency arena and has nothing to do with the intrinsic value of thermal heat transfer coefficient which dictates how fast that heat is lost to the outside environment.

Hey check out 'loyds blog'- he has alot of good ideas there and just came out with a book all about tiny houses and sustainability. If you really want bugs in the hair check out sustainable building in coquille oregon. I believe they have workshops on building with mud and straw etc. :) Cool Project!

The $20,000 dollar house has a roof on it now and we are almost finished with the siding. I'll probably try and put the wood burner in in October. It's a little harder to get it going after teaching all week but my wife and IU made a pretty good jump on everything this summer. I'll try and remember to bring a camera.
It's not really fancy but it is coming along OK, The wallls are 2X6 with 1" pink styrofoam added to achieve an R value of around 25 total. I think ?I'm going to blow in cellulose for the ceiling insulation. All the doors and wiondows went in well.
To keep the cost down I was going to use used siding but I did not store it correctly and it started to rot. This was actually fine as we ended up buying new siding and it looks fabulous.

I only got as far as the first line I'm afraid ... a small (1000 square foot) home for USD 20,000 ...
Just been looking at some small (250 square foot) homes for USD 500,000. Need a little renovation mind you you, but still an opportunity ...

In my neighborhood in San Diego, it might cost $20000 for just the aesthetic/environmental review, even for a remodel. This is a pre-permit approval. Then you pay all the other $$$$$ permit fees, then the construction costs.
