Hobbit houses and hempcrete
 
Yes, both are something I'm interested in professionally for the future, but right now it's strictly personal.

I want to build a 'hobbit house' (scaled for size of course) in a rural area and wish to use hempcrete as I learn more about that.

Does anyone have any experience with either?

I honestly can't help with it but I came across this video, it may give you some ideas. Not sure if this is what you meant or not but thought I would share anyways:

Not that experienced with concrete, but have done my share.
Same with Hemp.

Never done them together though. That's be a waste of Hemp, I'm thinking.

This little gem is just outside of the DC line....

I doubt it is built with Hemp, but who knows.. could be.

A little bland, but I still like it.

I imagine that one would sit on the market awhile waiting for the right buyer to come along.:laughing:

I'd imagine you'd have to wrestle with county coding issues. And even if they let you you do it you'd probably have to fork over some serious cash to an engineer who would go to bat for you. Heck I think strawbale building, earthships and cordwood homes are still frown upon by the county gods.

Does it have to be hempcrete? This article says it's not for structure "http://www.americanlimetechnology.com/what-is-hempcrete/" rather for "insulating infill." What about doing cellular concrete instead? You can make it dirt cheap, it's both for structure and insulation, and lasts forever.

Strawbale is incorporated into the building code out here in Cali, but it's infill only, no piece of cake. An interesting side note is it was hoped that rice straw bale housing was going to take off in Cali because as it is the way the rice straw is disposed of is by burning as it has so much silica it doesn't decompose very well out here.

It doesn't have to be hemp, you can use just about anything you want - moss, old cloth, ...

I don't think you can get it delivered in a concrete truck though.

Hempcrete!
 
Hempcrete is a wonderful building resource!

You may find that it would work good for your hobbit house considering its composition and how it takes form.

Some things to consider...

- Hempcrete is not structural so you would still need some bones in the walls. However it will replace your paint, caulk, sheetrock, insulation & exterior siding.

- Building a dome or round shape house could be time consuming because of the special shaped forms you would need. (However I have heard of it being sprayed with the proper equipment ... but dont know enough about it to comment on it. )

- Hemp and lime can be expensive considering its import costs. Most of the lime comes from France or parts of Europe. The hemp can be imported from Canada, Netherlands and China ... gross. HOWEVER! That is starting to change considering the new legality with industrial hemp in the US. We will see those costs go down as Hempcrete building becomes more popular.

Some GREAT benefits of hemp include:
- A bio-monolithic, living, breathable wall system
- Regulates moisture and temperature
- Creates a healthy breathing atmosphere
- Decreases heating & cooling needs
- Mold, insect and fire resistant
- A renewable resource that grows almost anywhere in the world
- Insulation properties up to R-30 in normal sized walls
- Carbon zero footprint
- Low maintenance, long lasting buildings
- Replaces chemical emitting & harmful building materials

There are hempcrete buildings being built all over the world from the size of your hobbit house to giant warehouses. I am thankful the technology and resources are finally making it to the US. Building a house like you are considering is a great way to promote and help spread the word on this amazing building technology.

There is a lot of good literature out there on the hempcrete mixing and casting technique. The Hempcrete Book: Designing and Building with Hemp-Lime Book by Alex Sparrow and William Stanwix was definitely one of my favorites.

Best to you and your project! :thumbsup:

These houses exist ready-made. You only need to assemble them.
