Let me introduce you to Rob Greenfield.  He’s an interesting man for a number of reasons but it’s actually his home that interests me right now.

Why do we spend 25 – 40 years of our life energy putting a roof over our heads when we could have a mortgage-free tiny house?

I’m sure that there are people out there who feel that they couldn’t live in anything less than four bedrooms, two bathrooms and a 3 car garage but, to me, this is what liberation architecture is all about.

iAVs/DWC Comparison

This project was the big winner this week.

I straightened up the leaning pier on the iAVs bed…


…and drilled the holes for the flange fittings…before lining the beds with the local equivalent of Duraskrim.


The flange fittings were bolted into place.


The DWC tank drain was straightforward enough…that’s a simple standpipe arrangement.  The iAVs drain was rather more complicated – in this particular application.  It features a section of slotted agriculture drain pipe covered in a fine mesh sock to provide for effective drainage while ensuring that the sand stays in place.

And then I waved my magic wand and 1.5 metric tons of sand moved itself into the iAVs bed.  I secured the liner edges with some pine battens to finish off the sand biofilter and DWC grow tank.


The sand that I obtained for this project is not ‘sand’ as we’d normally think of it…it’s glass sand.

I used it because it satisfied the criteria for iAVs sand…it’s inert, free of silt and clay and it’s particle size range is such that it will drain very well.  It was given to me so the only cost was for the transport from the mainland to our island…a mere $80.00.  That it’s made from recycled bottles is a nice little sustainability bonus.

That’s it for next week so, until next week, keep growing – and take it easy.
