Pop-Up House: The affordable passive house

I've said this on previous threads, the problem isn't the availability of cheap building material or designs, it's the availability of cheap land. There's no pop-up property unfortunately.

Did they leave the foam exposed when they were done? That&#x27;s not really a good plan.<p>They don&#x27;t prepare the ground first? Isn&#x27;t the house going to sink during the first heavy rain?

Suspiciously absent from photos: plumbing and electrical.<p>What good is &#x27;outstanding insulation&#x27; with no heating&#x2F;cooling?

LVL on grade? How is that not going to rot?<p>You could probably get around that by pouring a slab with small stem walls and building inside that, but that&#x27;s not what they&#x27;re doing here...

This concept would be awesome as a tiny house.<p>My 7-year-old daughter just asked me the other day, &quot;We can build a tiny house when I&#x27;m 11, right?&quot; So I have another four years before I need to do something like this in tiny house form.

&quot; It must:<p><pre><code> – Have strong thermal insulation without thermal bridges, – Be perfectly airtight, – Capture maximum solar energy.</code></pre> &quot;<p>Perfectly airtight? With wood and insulation?

&gt; For the structure and insulation of a PopUp-House building (floor, walls and ceiling) it costs about 200 €&#x2F;m² including labour. To this cost must be added all the finishes: waterproofing, exterior finishes, interior finishes, electricity, plumbing, heating, etc.<p>What would be the total total cost then?

I like the design, and like the speed. I even like the music in the video.<p>But I cannot avoid thinking of the wolf, huffing and puffing and .. blowing that thing away. How stable is that thing?

Unless that PSE allows water vapor, this house can&#x27;t breathe. Even in a dry climate, it will eventually get mold and mildew building up inside.

It absolutely amazes me how all houses in US seem to be build with 100% wood, especially in areas with termites, dryness or possibilities of hurricanes!<p>It is not that much more expensive to build a solid concrete block home, insulate and airtight it well<p>I realise wood is more plentiful in US than here in Europe, but imho i wouldnt feel safe living in a wooden home.

For lots of stuff along these lines, Kirsten Dirksen has alot of interesting videos on youtube where she explores cool houses: <a href="https://www.youtube.com/channel/UCDsElQQt_gCZ9LgnW-7v-cQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;channel&#x2F;UCDsElQQt_gCZ9LgnW-7v-cQ</a>

These alternative house construction strategies always get my attention. But the real tough part is finding affordable and desirable land upon which to build one.

Are there more environmentally-friendly alternatives than polyurethane foam insulation? The insulation in my home include recycled jeans material.

I have a suspicion that once they encounter and solve all of the challenges associated with building houses (mold, cost, weather, a second floor) they will end up approaching a pretty normal modern residential construction.

I wonder what the earthquake&#x2F;hurricane&#x2F;storm strength of this stuff is.

Where is the bathroom?

No thermal mass makes for a horrible passive house.
