Building houses out of recycled plastic

Posted by Louisa McKerrow (Admin) Oct 13, 2016 Posted in Blogs

An interesting idea worth talking about…

Craig Allan, from the Dollhouse Construction Company, is exploring partnership opportunities within New Zealand in the form of developing and or manufacturing components essential to the construction of the building houses out of recycled plastic.

The Dollhouse Construction Company’s Plastixhomes entry is not eligible for the WWF-New Zealand Conservation Innovation Awards, as an ideas submitter must be a resident or citizen of New Zealand or that group or entity must be either registered in New Zealand or carrying out business in New Zealand.

However, the Conservation Innovation Hub is all about inspiring, generating, and developing new ideas, so please read on to learn more about Craig’s idea…

“Hi my name is Craig Allan, from the Dollhouse Construction Company. I am a 53-year-old man from South Africa, currently living in Waihi, New Zealand. For a long period of time, I’ve had this idea which I believe will rid most of the world of the excess plastic by building houses out of recycled plastic. I went onto this WWF site with my idea, because I studied wildlife conservation and game ranging in South Africa. My passion is wildlife and the conservation of it.

I am looking for a partner from New Zealand who wants to do something about the excess waste plastic problem which affects oceans and wildlife.

Plastic waste could be sourced from community-based collection stations and sea waste. This idea is new and unique – it has not been done before. This idea could benefit world wide communities by means of waste collection and eliminating housing problems.

I have this idea of building houses out of recycled plastic. All the framework and trusses can be constructed out of plastic. A fire retardant is added to the plastic to make the building more fire resistant. In the case of a fire, the plastic will slowly melt and parts that have melted can be replaced as they are needed. Wood – on the other hand – can rot and decay.

In my design, all the framing is extruded in waste plastic to the standard sizes of building. Standard 3x2,4x2,6x2 beams are extruded for lintels. The good thing is that plastic doesn’t expand and contract as much as wood. Plastic can be cut and fitted together like wood.

Two litre soda bottles - that are a total menace to the environment - are filled with excess plastic wrappers and bags, and fitted to the inside panels of the walls for insulation purposes. These are also sprayed with fire retardant material so it will not burn. Once the frames and panels are in place, the walls can be jib borded as per usual. Another option is to jib the interior and extrude weather board for the outside.

If you are interested in hearing more and seeing the drawings, please contact me.  I am looking for a partner who is from New Zealand who want to do something about the excess waste plastic problem to clean up our oceans through building houses with extruded recycled plastic. This project needs investment for development, awareness, and start up capital for machinery and collection.
