Plumbing and wiring

Before the hempcrete (the insulation) is sprayed on to the walls (week of 9th November) all the things that need to be hidden in the walls need putting in. Or as close to all of them as we can manage, it will be possible to channel out where we need things that we forgot or could not practically do in advance (for example pipes to take water in to the rest of the house).

The electrician has been and started the electrics. It is done a bit different to if we were using plasterboard as the plugs need fixing to the wall behind and to bring them to level with where the hempcrete and lime plaster will end up, they are screwed to bits of wood attached to the stone. This is because the hempcrete isn't strong enough just to set them in that.

The ventilation for the plumbing in this room is done (it vents out to the roof - this is so that airlocks don't form in the outflows and it vents to the roof so any smell goes outside). The pipes on the wall here will do the shower and sink as well as the temporary toilet which will be in the corner while we live in this room as we do the rest of the house. Pink lines on the floor show where there are pipes underneath.

 This is where the shower tray will go, with the outflow in the centre of the picture. The floor of the shower and the rest of the floor are going to be flush.
The pipe in the top right of the photo is for the grey (ie not toilet) water coming from the bathroom above. It will flow through a heat recover pipe, so that any heat from the water running away will be transferred in to incoming cold water to save energy.

The shower tray. It is pretty darn huge at 120 x 120 which doesn't really show here. This is with the intention that in the future it is for hosing down dirty things like the dog and a bit of space will be nice then as well as in the short term while it is our actual shower too.
