Tiny House Construction Waste

In an effort to tell the whole story about tiny houses I felt it necessary to show the not so pretty side of tiny houses.  Namely, how much waste a tiny house generates in its construction.  The reality of how much waste I have created in building my home really shocked me when I saw all the scraps loaded up onto a single trailer, ready to be hauled away to the dump.

This was a real reality check that even tiny houses have an impact, which of course I knew, but knowing something  and facing the reality in the face are two different things.

A parallel for me personally – which may seem odd and obviously a much greater moral implication – was the first time I personally participated in “processing” a chicken.  To be standing there, a knife in my hand with a live chicken before me, there was real coming to terms with what I was about to do.  As a meat eater, it was the first time I personally had to grapple with the reality of eating meat.

I had a very similar experience when I stood in front of that trailer and was processing the fact this trailer was going to be taken to a dump and I was the cause of it.  That I was creating a large amount of trash that later generations would have to contend with.  Do I have that right?  Am I okay with that?

So the above shot is pretty much all of the waste that my tiny house created.  In this trash there is all the scraps from the framing, sheathing, roofing, siding, etc.  Also here you’ll see the packaging that comes with some building products, along with some plastic sheeting that I used to cover materials that has since been torn or degraded to a point that I can’t use it any more.  In total it’s about 400 lbs, it looks like a lot more, but it isn’t stacked very efficiently.

I also wanted to provide another side of this story by comparing how much waste I created to that of a traditional home.  The typical home in America is about 2,600 square feet and in its construction generates about 2.5 tons  (5,000 lbs) of garbage.  It’s important to note that this is the onsite trash only, components like trusses and roof farmings are built elsewhere, but not accounted for.   You can read about these statistics in this study (link no longer works).

Now I think its also important to talk about how I could have done better, while I need to come to terms with this amount of waste, hopefully I can help others reduce their waste.

First off it is important to note that it honestly is impossible to not have waste.  We can also use reclaimed materials, which can help us reduce our waste and even offset the waste we create; the ultimate would be to have a net negative impact, but I think that would be tough.  There is also a strong argument for inhabiting houses that are already built or could be rehabbed with less impact.

Our writer here on The Tiny Life, Andrea, told me once that she thought it would be impossible to have a house built of more than 95% reclaimed materials.  Her house was about 80-90% reclaimed, but she had one huge advantage: She built her tiny house in a warehouse that was a building materials reclaiming company!  That’s all they did, was reclaim materials and even with that, she was not able to achieve more than 80%.

Other things that might help you reduce your impact is being more efficient with materials.  I think it would be tough to improve upon how I utilized my materials, but I figure I could have been better at it with enough practice.  I also think that if I had a good storage space, I could better save and organize the scraps so I can keep the quality up and utilize them better.  There were some pieces of wood that got damaged by rain after a tarp blew off in a storm, leaving the wood exposed to the elements and water pooling on it.

Finally, if I had chosen all my materials to be chemical free (no glues, resins, treatments) I could at the very least used the scraps to burn for heating or campfires.  But in some cases I opted for treated lumber (which I still feel like was the right choice), but it meant that I shouldn’t burn it.

Building Philosophy

I saw this video originally on Tiny House Design’s page, but thought it was so excellent that I needed to share it here.  This video talks about how using natural wood that he milled himself and integrating a hand made aesthetic really impacts you deeply.  There are a lot of really great gems in this one, so be sure to check it out.

Cracking The Code – Updated!

Cracking The Code - A guide to building codes and zoning for Tiny Houses_Page_001Many of you have checked out our ebook Cracking The Code – A guide to building codes and zoning for tiny houses; well today I have some good news!  We have updated the ebook and added 14 more pages of core content to the ebook with our Toolkit!

Here’s the kicker!  If you bought the old version, I just sent you the updated version for FREE!  So those of you who supported The Tiny Life, thanks so much, we hope you’ll enjoy the free update.

The Toolkit comes out of some great feedback we got from the first version, where I presented what I came up with as the single best approach to tiny houses and building codes.  What we have learned since then is that people were able to take what we taught them and then started coming up with some creative ways to make tiny houses legal in their own towns.  So I took those approaches and created this Toolkit which teaches you 10 additional ways to make a tiny house legal!

Boxman Tour

So I recently had the fortune of getting to tour what might be one of the biggest shipping container building companies in the US.  Which happens to be right here in Charlotte.  While they happened to be local, they have been developing container buildings all over the place.   A lot of what they do is pop up trade show booths, but I was clued into some neat full building projects on the horizon.  Here are some photos from my tour, check them out here

RTM_7848Below is a few sections of an office that is being built.  You can see how they reinforce the insides so that they can stack them.  This is just part of the office.

Tiny House Sheathing

Playing catch up with the posts about building the house.   I went and ordered my sheathing for the walls and roof.  There is a newish product that I am using called the Zip system.  (zipsystem.com)  Basically it is wall and roof sheathing with the house wrap/roof felt already on it, which is pretty fancy.

It also has these little nubs on the edges so you don’t have to worry about expansion gaps like you would with traditional sheathing.  Along with the spacers, the board is printed with markers so if you do your walls correctly, you can just follow the guide on the boards and you hit a stud every time while securing it from the outside where you can’t see where the studs are.  The kicker is that not only does it have some major time and labor saving factors, it costs a lot less!  You have to use their special tape, but its about 1/2 the price of tyvek tape, so that isn’t a big deal.

Sheathing your tiny home

I priced it out and its much cheaper and then you don’t have to spend all that time house wrapping.  The vapor barrier on the zip panels does the exact same thing as tyvek, but its more durable and isn’t prone to being pulled off by inclement weather.    It also apparently makes a much better air seal and is LEED Credit Certified.

 

Traditional sheathing: 18 sheets @$28
Tyvek Wrap: 1 roll $150
Tyvek tape: $100
Roof Felt: $19
Capped Nails: $7

So when it comes to sheathing (which is what the plywood on the outside of the house are called) the trick with it all isn’t the actual plywood, but that you did your framing correctly.  If you have done your framing correctly, then the seams of each of your pieces of plywood will land right on the stud.  This is important because you need to be able to nail the edge of the sheathing to that stud.  There will be some cases where a panel lands on a window, so you will need to place an extra 2×4 piece to have something to nail into, you can see below an example of this.

installing sheathing

This photo also shows how in tiny houses we screw and glue our sheathing.  Here I used liquid nail on the studs.  A piece of advice for anyone who is doing this, help yourself and spring for a air powered caulk gun.  I tried to do this for one day and by the end of it I swore I gave myself arthritis because how hard you have to squeeze this stuff.  They have a lot of better powered caulk guns for $150-$350, but this gun is $35 and well worth it.  To give you an idea of how much you’ll be doing this, I went through about 40 tubes of this stuff while building my tiny house.  As far as fastening the sheathing, I used 2.5″ exterior grade screws, every 6 inches on the edges and 12″ in the center (field).

In the video and some of the photos you can see that the sheathing is actually larger than the wall frame.  I had the sheathing extend below the wall framing to hide the trailer so that you’d really only see the tongue and fenders, the rest of the trailer is hidden behind, once finished, nice looking cedar siding.  I also had it extend above the framing because I could wanted the sheathing to tie into the loft beams, flooring of the lofts, and the silplate.  So I carefully calculated the height of all the components listed and a few others, so that when I installed the silplate (that the roof rafters sit on) it was perfectly flush.  This

The other key thing to know about the overhang and extension was that this then tied all three systems together to be a very strong unit.  Effectively the floor framing, the wall framing and the roof became a unified piece because they all were brought together by the sheathing.
