How we made our Cob Floor

We have just about finished our cob floor and it looks and feels beautiful. As such I thought it necessary to start the blog post about how we did it. It was a lot of work but the techniques weren’t all that difficult. Here we go First up level the places in your home that…

Hang pictures on a cob/stone wall

Hanging things on walls built with natural materials generally requires different techniques from a modern build, and sometimes a bit of pre-planning. We are at the stage of our build where we are rendering the walls with cob and we know the layout of the rooms. As such, we are comfortable to start deciding where…

If possible I would recommend building your window and door frames before starting your walls, that way you can build up to and around them and keep everything nice and flush.

Can you fit vents to a cob wall

Yes. And actually, if you have them ready whilst you are doing you final render you can push them in to the wall a bit to make them absolutely flush. Also make sure to tilt the vent forward a bit to make sure that any water landing on top will fall away from the wall…
