A layer of building wrap is added over the cob-covered straw bales and then geogrid (plastic mesh) over that. The lime render will bind to the geogrid when applied.

Cob ready for the straw walls.

Internal walls are combination of curved & straight gib board along with the straw bales.

The exterior walls are covered with tarpaulin to protect the lime render while it sets. The foreground shows the basecoat.

The secondhand billboard tarpaulins provide some welcomed colour.

Gale force winds whipped off the tarpaulin and blew it onto the freshly applied lime render. The day was spent re-trowelling and sponging the plaster to make it smooth again.

Ceder shingles are added to the gables.
