Green Home Building and Sustainable Architecture

Sustainable architecture is an exciting and important field, with many people reviving traditional methods of building and others creating innovations to established practices. Kelly Hart, webmaster of the popular website, posts text and photos featuring what he discovers from around the world.

Kelly Hart has been involved with green building concepts for much of his life. He has also worked in various fields of communication media, including still photography, cinematography, animation, video production and now website development. Kelly has lived in an earthbag/papercrete home that he built (but is now mostly living in Mexico) and consults about sustainable building design.

I have gotten the following information from a Canadian inventor who claims some pretty amazing attributes for a product that he calls "New-crete." While it is not yet available, it has the potential to become one an amazing manufactured technology that addresses many issues related to sustainability. See what you think:

I have a patented product of lightweight cement called new-crete. New-crete is designed to form millions of air bubbles when cured. This makes new-crete 50% lighter and stronger than regular cement and 35% lighter and stronger than lightweight cement. It is also 30%-40% cheaper than regular cement. It has an R-20 insulation value with a 9-inch thick wall. It is nontoxic and not corrosive and it floats.
  • Price: regular cement , $125 per cubic yard; new-crete, $75 per cubic yard
  • It has the ability to shed water with a .5 mm saturation point. this will prevent water seeping into it and freezing causing cracking.
  • The ingredients to make New-Crete are readily found around the world and are in no danger of being depleted.
  • New-crete can be formed into any object. We have the designs for walls, drywall, floors, shingles, stairs, window frames, cupboards, bricks, doors ect....we can make a whole house from the bottom up using only New-Crete
  • It can be painted, or laminated with wood panels, ect.
  • It can be nailed into and not crack.
It is designed to be processed in a controlled environment so it can not be poured. That is why we need a $2 million processing plant to start manufacturing pre-fab homes then ship them by train or boat anywhere in the world. Before that, we need about $150 000 to build a prototype home so we can get it approved by CSA (Canadian Standards Association).

Once this is up and running we can start supplying the world with better, cheaper homes. The plans for the prototype home is for a regular box style home. The next step will be to make in-ground and underground domes that are storm proof. They will also be cheaper and strong than regular homes with revolutionary designs...100% self sustainable.

The Canadian north (native reserves) are in much need for about 35 000 new homes as the old ones are in 3rd world condition.

So I know this will be better for everyone, especially the trees. This will change the world. All I need to do is find $150 000 to get it started. I see many people with lots of money (US government spending trillions on war) and the Canadian government also spending money on war ect...the will to change the world is the first key; money will then come naturally.

I believe we must start using other building materials instead of trees before they are all gone. If interested you can contact Matthew Smyth at or visit his website:

New Website:!

I am very pleased to announce the launch of my new website, Actually this is a cooperative project between myself and Dr. Owen Geiger of the Geiger Research Institute of Sustainable Building ( Owen and I have known each other for several years and have much respect for each other's work and for the potential of building sustainably with earthbags. To find out more About Us, see this page.

As the banner proclaims, our main attitude is that of sharing information and promoting earthbag building. We expect this to become the premeir site for learning about how to build with earthbags. While the site will be expanding over time, it already has a wealth of information.

Under the heading of Projects and Pictures we have already featured 17 earthbag projects from around the world, and we have plans to show many more. These pages are quite rich with photos and text that explain the nature of the projects, which range from residences to studios to walls to public buildings.

We have already posted 11 Articles about earthbag building, some we have written and some by other authorities on the topic. I have written a short History of earthbag building as well. So far we have 3 articles about Testing earthbag technology.

We have posted 4 pages devoted to the use of earthbags for Emergency Dwellings, and feature several other Plans that are available for more lasting structures.

There is a lengthy section with FAQs gleaned from my years of answering questions from the public at

Our page of Resources features links to other related sites, books and DVDs that might be purchased, and where to buy supplies for building with earthbags. If you are looking for ways to get involved through Workshops, this page might help you find one.

If you are seeking specific information about this technology, we have provided a couple of Search engines to fascilitate this. One of these is set to search a selection of content-rich resources.

And finally, we are launching a Blog that is specifically about building with earthbags, where both Owen and I will be posting more information and provide a way for you to share information with us through your comments.

I hope you enjoy browsing and benefit from this new resource!
