Looking back at that what did you use as your slab in the end?


We're not using a slab as such. The walls are supported by a composite plinth wall (outerleaf stone and inner leaf Foamglas block) infilled with pea gravel to ground level and then Technopor above that to floor plate. This sits on 200mm deep compacted single grade stone.

The floor is 250mm Technopor on compacted sub-soile followed by 65mm limecrete.



Glossary: Foamglas is aerated closed cell recycled glass available in sheets or blocks. It is an excellent insulator, waterproof, light weight, and has good strength characteristics.

Technopor: Same material as Foamglas but granulated.

Limecrete: Lime mixed with light weight aggregate generally used for flooring.

What`s the current situation regarding mortgages on straw build house`s already been constructed?

My thought`s being are they similar to that of timber framed of several years ago,that one could not get a mortgage on one that had been constructed previously if it was nearing its 25yr anniversary,

Or have the regulations changed.


That will be down to the mortgage lender and how they assess the risk.

Straw bale build is well understood and easily exceeds (often out preforming traditional brick & block) all building requirements.

Waiting for building regs to be approved so we can start digging. CSH is well underway though.

Top soil varies from nothing to a foot or more. Sub soil is clay and fragmented rock. The clay portion is not overly high and the fragmented rock allows for free draining but with good compaction.

No rock here, just different types of clay

We're after some clay for internal rendering. Essex is a bit far though.

We've disposed of most of our physical servers and host everything bar Anglesey County Council and JNCC on Microsoft Azure.

One dept. or person getting the credit for all the scientific work that's preceded his report. I guess that's the way of the world.

You know very well that until a man in a white coat with impresive equipment says it works it doesn't.
Tis the way of the world.

Vegplot,
You are the most clued up on here with the straw build construction due to your own project,

But are not these houses that are protrayed in this Bristol scenario,merely straw insulated,not straw built as in the sense of the word,as the steel construction seems to be the load bearer of the roof ,unlike your more traditional method?
