We had good weather to work on our house building project today after I got back from getting some building supplies.
The first floor joists were put in this afternoon and it is really satisfying to see them sitting on the beams that span the “stilt” style foundations. We have a very sloping site and so the southern face of the house will be close to six foot off the ground on sturdy stilts which are on concrete pads. The concrete pads are set about three foot into the very solid clay subsoil.
We really would have liked to avoid using concrete however we really could not afford the alternative of cut stone and there is no stone naturally occurring on our site. There are some compromises which we find we are making, mainly due to budget constraints – our budget actually being almost non-existent!
Our floor design will be a little unconventional – quelle surprise! We are fixing galvanised chicken wire between the tops of the sturdy beams and on top of this we will spread a breathable fabric which will in turn be fastened to the tops of the beams. The floor joists will then sit on top of this fabric, nailed to the top of the beams and the spaces created will in time be filled with insulation and the floor boards screwed down to the joists.
We will not be adding the insulation just yet for two very good reasons – firstly we need to get the roof on in order to keep the insulation dry and secondly at the moment we do not know what sort of insulation we will use.
The second consideration will depend on budget – if we win the national lottery – highly unlikely but not impossible – if only we remembered to buy tickets!! I digress – if our budget changes we would love to use sheep’s wool or something similar.
What is more likely is that we will source some local timber and use our free electricity and an electric planer to create wood chips which we could mix with lime and maybe some hemp hurds and a little water to create a sort of woodchip insulation.
Any suggestions about alternative, easily sourced, environmental insulation will be most welcome 🙂
