It would have been better to fix building paper to the frames before they were planked, but I didn’t remember to ask Woodulike to do that so I spent a fair bit of time wrapping it round the frames and stapling it in place. Then filling the spaces between the frames with glassfibre insulation and adding another layer of building paper. The idea is the paper keeps out drafts that would otherwise blow in between the planks, but allows air to permeate preventing condensation building up in the cavities.
The fireplace is built out of old bricks dug out of our ‘brick mine’ and sawn in half using a tile cutter so they take up less room. The stove is, naturally second-hand and had two missing legs. That worked out well though since without the rear legs it can fit tighter into the corner resting on a steel beam cemented into the brick wall.
The tiles came from the same place as the bricks. The chimney goes straight up, using twin wall stainless steel pipe for the section that passes through the roof. There’s lead flashing under the shingles rolled up around the flue pipe sealed with ‘Flashband’. The chimney cowl is a cheap stainless steel dogfood bowl!
The interior walls are finished with 15mm plasterboard. Heavier than most people would use but the frames are quite widely spaced and I want them to be rigid. Heavier board also adds to the thermal mass retaining some heat and keep the noise down too. I’m useless at plastering so I just filled the gaps and painted the boards.
By this time the temporary chipboard floor was totally ruined and quite mouldy from the soaking it got months before, so I threw it away. I put 50mm rigid foam from Seconds & Co on the slab and topped it with 12mm ply and cheap carpet.
The furniture is all old stuff from the house we’ve been hoarding for years in case it came in useful.
*Brick mine. This area of our ‘garden‘ was the site of six tiny cottages that were rendered uninhabitable around 1960. We’ve cleared some of it for parking and are gradually mining the rest for building stone, bricks and tiles.
