Tedd. Excellent articles, a starter 'kit' that could be weathered quickly would be a beginning. Here in the UK despite recent lessons you can feel the pressure building to jump back onto the rollercoaster. Peter.
Tedd,
Been loving this series, especially since I'm going through the exact same efforts and calculations myself right now (with the same family of four to accommodate and a business to run...). I ran your numbers through an inflation calculator out of curiosity. For reference: $36,000 in 1979 is the same as $105,000 in 2009 dollars. It still doesn't sound out of line for what you built. And your monthly payment of $600 would be $1,757 today.
Jesse,
Thanks for checking the inflation calculator. I should have done that. At 105,000 in today's dollars, I enclosed 2500 s.f., but finished only a little over 1000 s.f. The total floor area cost about $42 p.s.f., which is a very, very good deal and the finished s.f. would be about $100 p.s.f., which is still good, considering how energy efficient the building is. Before I'm done with the series, I'm going to find out what it would cost our company to produce a building with similar R-values, volume and square feet. I don't know the answer, so I'll be as curious as anyone to find out how we do. Stay tuned. TB
Tedd,
Just finished reading the series of blogs ("How To Build...), and found it right up my alley - comforting to read, actually. This is much like my sort of evangelism - you can have anything you want, though it be only the one thing. As an added blessing, doing the work yourself has a reward that only people that have done so understand. I'm about your vintage, but I'm still excited about the possibilities. It helps that I have a full-sized bandmill in the backyard. I've just bought "The Timber-Framed Home" and look forward to working with your organization in the future. As you well know, you could not have done this without a terrifically supportive wife. Thanks for the blog...
I've watched the Weston house episodes of TOH at least 3-4 times now, and when I say watched, I mean watch, pause, rewind, and at times watch again in slow motion. I put together a 2-page description of Open-Built to show around my office, and with some University colleagues. I find this absolutely fascinating.
My knowledge of home design is limited to 15 years of watching TOH, but I do have expertise in the area of Digital Manufacturing; helping companies in Aero, Ship and Auto develop their manufacturing, procurement, and execution systems using 3D product designs. Creating 3D designs and sending the data to CNC machines? We do that in Auto. Flipping the assembly upside-down to make assembly easier? We do that in Ship (in Bath, ME for example). Build major subassemblies in one location then final assemble them in another? We do that in Aero. (Of course we do all of these things in each of these industries.) I have a thousand random thoughts, but I should probably keep this short in a blog response. Here’s a few: - Could you use this method to build 1500 homes per month? I know that’s a huge number, but over 200,000 homes were lost to Katrina. 1500/mo. means 18,000/year or about 1 decade to replace all of them. OK – so maybe there’s a housing glut and they shouldn’t all be replaced. What would it take to do 150/month? - What if the method was applied to HfH or the Fuller Center? (My Aunt does some counseling for a Fuller Center group that responds to disasters.) I read an article in our local paper about an HfH effort in Bay Saint Louis, MS. Habitat members (and anyone else) who wanted to be involved needed to provide their own transportation to the site, then someone would organize them once they got there. It was a one-week minimum assignment, and the cost/time of transportation was borne by the volunteer. This requires a good deal of effort by the volunteer that doesn’t actually build a home. But what if the designs were developed in 3D, the 3D data then distributed around the country, and volunteers could spend a weekend building major subassemblies within 30 miles of their own homes (thus reducing the strain on the limited facilities in a recent disaster area). The assemblies would be shipped and assembled onsite. (Of course workers would still be needed onsite, but I think we could get more volunteer hours spent working directly on the building homes.) - And I don’t think these should all be identical row houses; with 3D designs and what Industrial Engineers call ‘mass customization’ (an alternative to ‘pre-fab’) there can be many, many styles of homes. (Believe it or not, no two cars are identical; there are enough body styles, colors, and options that the number of possibilities exceeds the number of models manufactured in a year; and each airplane and large ship are individually designed. It gets into a topic called 'Configuration Management'.) - But I also wonder if pre-building assemblies leads to paradigm shifts in the area of home inspection? My understanding (again, I’m not a homebuilding guy) is that inspections tend to be local. TOH showed the electrical being done in Walpole NH, for a project in Weston, MA. Did the Weston inspectors commute? Or – could it be more like Aero, where the assembly planner defines the processes where inspections need to be made, and an inspector signs off on the inspections and records the information to a database, forever to live in this case with the house? (Anecdote: every hour of assembly on a Boeing 747 requires 4 hours of planning and 4 hours of inspection, and THE PAPERWORK WEIGHS MORE THAN THE PLANE!) - In fact, this leads to another value that I don’t recall being mentioned on TOH. The owners have a 3D model of their house. I didn’t say that right - THE OWNERS HAVE A 3D MODEL OF THEIR HOUSE! I realize that your wall panel design limits the need to know the location of the studs, but wouldn’t it be great to know of that your new Queen size mattress will fit up the stairs? Well, this has gone far beyond a short blog response. I’d be curious to Tedd’s or anyone’s thoughts. FWIW - I have a Bio on LinkedIn: http://www.linkedin.com/pub/patrick-hillberg/a/839/141
Pat,
Our system can be scaled, though I don't know if those kinds of numbers would be desirable. It would probably be better to distribute the production to additional operations. GM is not a good model for what we're trying to achieve; a better model is Home Depot or Lowe's where additional stores are added as needed. On the subject of inspection, we haven't had difficulty working with local inspectors because our Open Built systems make the plumbing and electrical installations open for inspection which is the primary issue. So, by using licensed professionals and giving the inspectors the ability to do their inspections, we don't have a problem. The 3D model is indeed a very useful, near term and long term. We are looking at ways to give our clients reader access to their model for future reference. Obviously, it would have to be easier to use than our professional software. We're working on that.
Wow, great post! It is a good example of why you should build incrementally now. There are great deals to be had. If I had more time I would share a few examples.
Did it cost quite a bit to turn the butternut trees into cabinets? That is a really neat idea.
The cost of the butternut boards was minimal. I traded a few other logs for having the butternut logs sawed into boards. I air-dried them before milling into cabinet doors, drawers and fronts.
