Build Your Own House

Obviously a mistake.

Man, you have way to much time on your hands!

Very nice job.

I know we have been here before, but I can't help myself - do you really think you need the containers? Looking at the finished product the original containers are almost invisible, I can't help wondering what advantage it has over framed construction...

I like the style though. You might consider folding the insulated envelope around the water tank, since you are almost there anyway. I like the idea of using water for thermal mass, especially on a lightweight structure like this.

What's the bet it all changes when you have an actual site to consider?

Very cool modelling Terry. As Bruce suggests, since you have removed so much of the containers from the structure of the building, perhaps you can move away from them altogether.

I can see the engineering of such a building being a nightmare. You may even preclude yourself from secondhand containers as weathering and age will affect structural strength and slicing them apart as your design looks to do would destroy structural integrity.

.

Hey Terry, don't take the questioning as my asking if you know what you're doing or proposing. It's good to get outside feedback that asks questions and poses problems you may not have yet thought about or found a solution to.

I think the idea of recycling and reusing is a noble goal, and we are doing that with our own build. There is also a massive surplus of containers world wide at the minute as you say.

I work for a company that imports/exports and I've seen these containers suffer structural failure when incorrectly loaded for lifting and stacking purposes. That second container with both long sides removed in your exploded view is likely to need some serious reinforcing work across the width of all three containers to stop your roof from bowing inwards.

Bruce's idea about using prefab steel (or wood) frames with suspended floor might be worth a further look just to compare costs of having a team on site for a 1-2 days to erect it versus the shipping containers and engineering costs. Since you are going to skin both sides (and floor/roof?) of the shipping containers anyway, you'd be comparing apples with apples in terms of the finished product.

.

Just to continue advocating for the devil...

Building structurally sound steel or timber stud frames does not need sophisticated skills. For steel you would need basic welding skills, a one-day workshop or a few hours with an experienced welder would be more than ample. For timber the ability to point a nail gun is about it. In either case the most important thing is careful measurement.

My dad built all his steel frames himself on site without assistance. He had done a few small welding projects (shelving mostly) but that was about it. He was in his 70's. Dad, my brother-in-law and myself raised all the frames in about 3hrs. With care you could probably raise the frames on your own - just make sure that you keep frame modules to a modest size. Once you get one corner right you are set.



I am sure you have put a lot of research into this, but have you put as much research into conventional framing? And the most important piece of research - what does your engineer say?

Look closely at this photo:


And you will see that all the interior walls are steel stud frame anyway. The exterior walls are steel stud too - add a few noggins and some diagonal straps and the containers become redundant. What the containers are actually contributing to this building is floor and roof framing (but you still need to install flooring and roofing).



The containers in your example do not make any significant reduction to the use of new steel in the building. The issue of stockpiled shipping containers is interesting, but only if you live somewhere where this is the case (in which case you will presumably be able to get the containers for free). Using shipping containers in an area where there is a demand for shipping containers for conventional use is not really recycling - it just means more new containers will be built.



This is a good point. Much will depend on your site, but there are several alternatives to building on a concrete slab, framed construction being the obvious candidate. Your containers will save you in bearers and joists, but you will still need footings.

Having said all that, if you want to build your house out of shipping containers more strength to your arm! My comments are not so much addressed to you as to other readers who may be tossing up various construction approaches.

Please accept my apologies Terry, the mistake was mine. I knew that you were not interested in dissenting views but I pressed on anyway.

I really like your design, I think you did a great job of modelling it and I am impressed with the amount of research you have put into it. Really, I only disagreed with one small aspect of your proposed construction (keeping in mind that once you have your house to lockup - walls, roof, floor, windows, door - you are less than halfway there). I didn't disagree because it was unconventional, I disagreed because I thought it was expensive, restrictive, slow and possibly not as environmentally sound as it first appears. I could be wrong, and I am open to that, but if everyone treats their preferred construction technology as a religion then it is hard for any of us to change and really hard for new members to make any sort of objective assessment.
